Create a new N: entry type in MAINTAINERS which performs a regex match
against filenames; either those extracted from patch +++ or --- lines,
or those specified on the command-line using the -f option.
This provides the same benefits as using a K: regex option to match a
set of filenames (see commit eb90d0855b "get_maintainer: allow
keywords to match filenames"), but without the disadvantage that
"random" file content, such as comments, will ever match the regex.
Hence, revert most of that commit.

It can accidentally happen that the faulting insn (the exact instruction
bytes) is repeated a little further on in the trace. This causes that
same instruction to be tagged twice, see example below.
What we want to do, however, is to track back from the end of the whole
disassembly so many lines as the slice which starts with the faulting
instruction is long. This leads us to the actual faulting instruction
and *then* we tag it.
While we're at it, we can drop the sed "g" flag because we address only
this one line.
Also, if we point to an instruction which changes decoding depending on
the slice being objdumped, like a Jcc insn, for example, we do not even
tag it as a faulting instruction because the instruction decode changes
in the second slice but we use that second format as a regex on the
fsrst disassembled buffer and more often than not that instruction
doesn't match.
Again, simply tag the line which is deduced from the original "<>"
marking we've received from the kernel.
This also solves the pathologic issue of multiple tagging like this:
29:* 0f 0b ud2 <-- trapping instruction
2b:* 0f 0b ud2 <-- trapping instruction
2d:* 0f 0b ud2 <-- trapping instruction
Double tagging example:

A bug was reported that caused localmodconfig to not keep all the
dependencies of ATH9K. This was caused by the kconfig file:
In drivers/net/wireless/ath/Kconfig:
---
if ATH_CARDS
config ATH_DEBUG
bool "Atheros wireless debugging"
---help---
Say Y, if you want to debug atheros wireless drivers.
Right now only ath9k makes use of this.
source "drivers/net/wireless/ath/ath5k/Kconfig"
source "drivers/net/wireless/ath/ath9k/Kconfig"
source "drivers/net/wireless/ath/carl9170/Kconfig"
source "drivers/net/wireless/ath/ath6kl/Kconfig"
source "drivers/net/wireless/ath/ar5523/Kconfig"
source "drivers/net/wireless/ath/wil6210/Kconfig"
endif
---
The current way kconfig works, it processes new source files after the
first file is completed. It creates an array of new source config files
and when the one file is finished, it continues with the next file.
Unfortunately, this means that it loses the fact that the source file is
within an "if" statement, and this means that each of these source file's
configs will not have the proper dependencies set.
As ATH9K requires ATH_CARDS set, the localmodconfig did not see that
dependency, and did not enable ATH_CARDS. When the oldconfig was run, it
forced ATH9K to be disabled.

Currently, randconfig does randomise choice entries, unless KCONFIG_ALLCONFIG
is specified.
For example, given those two files (Thomas' test-case):
---8<--- Config.test.in
config OPTIONA
bool "Option A"
choice
prompt "This is a choice"
config CHOICE_OPTIONA
bool "Choice Option A"
config CHOICE_OPTIONB
bool "Choice Option B"
endchoice
config OPTIONB
bool "Option B"
---8<--- Config.test.in
---8<--- config.defaults
CONFIG_OPTIONA=y
---8<--- config.defaults
And running:
./scripts/kconfig/conf --randconfig Config.test.in
does properly randomise the two choice symbols (and the two booleans).
However, running:
KCONFIG_ALLCONFIG=config.defaults \
./scripts/kconfig/conf --randconfig Config.test.in
does *not* reandomise the two choice entries, and only CHOICE_OPTIONA
will ever be selected. (OPTIONA will always be set (expected), and
OPTIONB will be be properly randomised (expected).)
This patch defers setting that a choice has a value until a symbol for
that choice is indeed set, so that choices are properly randomised when
KCONFIG_ALLCONFIG is set, but not if a symbol for that choice is set.
Also, as a side-efect, this patch fixes the following case:
---8<---
choice
config OPTION_A
bool "Option A"
config OPTION_B
bool "Option B"
config OPTION_C
bool "Option C"
endchoice
---8<---
which could previously generate such .config files:
---8<--- ---8<---
CONFIG_OPTION_A=y CONFIG_OPTION_A=y
CONFIG_OPTION_B=y # CONFIG_OPTION_B is not set
# CONFIG_OPTION_C is not set CONFIG_OPTION_C=y
---8<--- ---8<---
Ie., the first entry in a choice is always set, plus zero or one of
the other options may be set.
This patch ensures that only one option may be set for a choice.

- ensure only one symbol is set in a choice
Changes v1 -> v2:
- further postpone setting that a choice has a value until
one is indeed set
- do not print symbols that are part of an invisible choice
For randconfig, if a list of required symbols is specified with
KCONFIG_ALLCONFIG, such symbols do not "have a value" as per
sym_has_value(), but have the "valid" flag set.

Because the modules' symbole (CONFIG_MODULES) may not yet be set when
we check a symbol's tristate capabilty, we'll always find that tristate
symbols are booleans, even if we randomly decided that to enable modules:
sym_get_type(sym) always return boolean for tristates when modules_sym
has not been previously set to 'y' *and* its value calculated *and* its
visibility calculated, both of which only occur after we randomly assign
values to symbols.
Fix that by looking at the raw type of symbols. Tristate set to 'm' will
be promoted to 'y' when their values will be later calculated.

The source tree can contain lots of uninteresting data like tag or

also break the build, if the tree contains an unrelated file named

This is merely inconsistent:
- adding the full path to the directory in the -I directive,
- especially since that path is already a sub-path of the system
include path,
- and then repeating the sub-path in the #include directive.
Rationalise each include directive:
- only use the filename in the #include directive,
- keep the -I directives: they are always searched for before the
system include path; this ensures the correct header is used.
Using the -I directives and the filename-only in #include is more in
line with how pkg-config behaves, eg.:
$ pkg-config --cflags ncursesw
-I/usr/include/ncursesw
This paves the way for using pkg-config for CFLAGS, too, now we use it
to find the libraries.

Viresh noticed when using merge_config.sh that a source softlink
was being created even when he didn't specify the -O option.
The problem arises due to the previous commit 409f117e2d
which added the -O option. Basically if -O is not specified,
we still pass '-O=.' to the make command, which then generates
a source softlink to ./
This patch adds an extra check so if there is no -O specified
to merge_config.sh, we don't pass one on to make.

Replace cmd_dtc with cmd_dtc_cpp, and delete the latter.
Previously, a special file extension (.dtsp) was required to trigger
the C pre-processor to run on device tree files. This was ugly. Now that
previous changes have enhanced cmd_dtc_cpp to collect dependency
information from both gcc -E and dtc, we can transparently run the pre-
processor on all device tree files, irrespective of whether they
use /include/ or #include syntax to include *.dtsi.

Prior to this change, when compiling *.dts to *.dtb, the dependency
output from dtc would be used, and when compiling *.dtsp to *.dtb, the
dependency output from gcc -E alone would be used, despite dtc also
being invoked (on a temporary file that was guaranteed to have no
dependencies).
With this change, when compiling *.dtsp to *.dtb, the dependency files
from both gcc -E and dtc are used. This will allow cmd_dtc_cpp to
replace cmd_dtc in a future change. In turn, that will allow the C pre-
processor to be run transparently on *.dts, without the need to a
separate rule or file extension to trigger it.

The current use-case for fixdep is: a source file is run through a single
processing step, which creates a single dependency file as a side-effect,
which fixdep transforms into the file used by the kernel build process.
In order to transparently run the C pre-processor on device-tree files,
we wish to run both gcc -E and dtc on a source file in a single rule.
This generates two dependency files, which must be transformed together
into the file used by the kernel build process. This change modifies
fixdep so it can process the concatenation of multiple separate input
dependency files, and produce a correct unified output.
The code changes have the slight benefit of transforming the loop in
parse_dep_file() into more of a lexer/tokenizer, with the loop body being
more of a parser. Previously, some of this logic was mixed together
before the loop. I also added some comments, which I hope are useful.
Benchmarking shows that on a cross-compiled ARM tegra_defconfig build,

The original patch which set up the dtc+cpp include path only considered
using those headers from device tree files. However, most are also
useful for kernel code which needs to interpret the device tree.
In both the DT files and the kernel, I'd like to include the DT-related
headers in the same way, for example, <dt-bindings/gpio/tegra-gpio.h>.
That will simplify any text which discusses the DT header locations.
Creating a <dt-bindings/> for kernel source to use is as simple as
placing files into include/dt-bindings/.
However, when compiling DT files, the include path should be restricted
so that only the dt-bindings path is available; arbitrary kernel headers
shouldn't be exposed. For this reason, create a specific include
directory for use by dtc+cpp, and symlink dt-bindings from there to the
actual location of include/dt-bindings/. For want of a better location,
place this "include chroot" into the existing dts/ directory.
arch/*/boot/dts/include/dt-bindings -> ../../../../../include/dt-bindings
Some headers used by device tree files may not be useful to the kernel;
they may be used simply to aid in constructing the DT file (e.g. macros
to create a node), but not define any information that the kernel needs
to share. These may be placed directly into arch/*/boot/dts/ along with
the DT files themselves.

Pass symbol-prefix to genksyms instead of arch, so that the decision
what symbol prefix to use is kept in one place.
Basically genksyms used to take a -a $ARCH argument and it used that to
determine whether to add an underscore symbol prefix. It's now changed
to take a -s $SYMBOL_PREFIX argument so that the caller decides whether
a symbol prefix is required. The build system then uses
CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX to determine whether to pass the
argument.

Fix symbol versioning on architectures with symbol prefixes. Although
the build was free from warnings the actual modules still wouldn't load
as the ____versions table contained unprefixed symbol names, which were
being compared against the prefixed symbol names when checking the
symbol versions.
This is fixed by modifying modpost to add the symbol prefix to the
____versions table it outputs (Modules.symvers still contains unprefixed
symbol names). The check_modstruct_version() function is also fixed as
it checks the version of the unprefixed "module_layout" symbol which
would no longer work.

We have CONFIG_SYMBOL_PREFIX, which three archs define to the string
"_". But Al Viro broke this in "consolidate cond_syscall and
SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to
do so.
Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to
prefix it so something. So various places define helpers which are
defined to nothing if CONFIG_SYMBOL_PREFIX isn't set:
1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX.
2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym)
3) include/linux/export.h defines MODULE_SYMBOL_PREFIX.
4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7)
5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym)
6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX
7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if
CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version
for pasting.
(arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too).
Let's solve this properly:
1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX.
2) Make linux/export.h usable from asm.
3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR().
4) Make everyone use them.

Allow K: entries in MAINTAINERS to match directly against filenames;
either those extracted from patch +++ or --- lines, or those specified

This potentially allows fewer lines in a MAINTAINERS entry, if all the
relevant files are scattered throughout the whole kernel tree, yet
contain some common keyword. An example would be using an ARM SoC name
as the keyword to catch all related drivers.
I don't think setting exact_pattern_match_hash would be appropriate
here; at least for intended Tegra use case, this feature is to ensure
that all Tegra-related driver changes get Cc'd to the Tegra mailing
list. Setting exact_pattern_match_hash would prevent git history
parsing for e.g. S-o-b tags, which still seems like it would be useful.
Hence, this flag isn't set.

Commit ef5da59f12 ("scripts/kernel-doc: handle struct member
__aligned") permits "char something [123] __aligned(8);".
However, by using \d we constraint ourselves with integers. This is not
always the case. In fact, it might be better to do char something[123]
__aligned(sizeof(u16));
For example, With wireless_dev defining:
u8 address[ETH_ALEN] __aligned(sizeof(u16));
With \d, scripts/kernel-doc erroneously says:
Warning(include/net/cfg80211.h:2618): Excess struct/union/enum/typedef member 'address' description in 'wireless_dev'
This is because the regex __aligned\s*\(\d+\) fails match at \d as
sizeof is used.
So replace \d with . to indicate "something" in kernel-doc to ignore
__aligned(SOMETHING) in structs. With this change, we can use integers
OR sizeof() or macros as we please.

On architectures which have symbol prefixes, depmod emits lots of
warnings like this:
WARNING: $module.ko needs unknown symbol $symbol
This is because depmod isn't being passed the -P <symbol_prefix>
arguments to specify the symbol prefix to ignore. This option is
included since the 3.13 release of module-init-tools.
Update scripts/depmod.sh to take extra arguments for the symbol prefix
(required but may be empty), and update the main Makefile to always pass
"$(CONFIG_SYMBOL_PREFIX)" to scripts/depmod.sh.
If the provided symbol prefix is non-empty, scripts/depmod.sh checks if
depmod --version reports module-init-tools with a version number < 3.13
otherwise it appends -P $SYMBOL_PREFIX to the depmod command line.

Commit 10b63956fc which plumbed in UAPI
broke the destination-y functionality of scripts/Makefile.headersinst.
The variable destination-y is used in a := assignment and so is expanded at
declaration time, and the include of the Kbuild fragments that set
destination-y to something is after this time, so it now always expands empty.
There are no in-tree users of destination-y, but it allows any
Kbuild-fragment to redirect where headers are installed.
Just move the assignment of the variable that uses it below the include
of the Kbuild fragment.

'make rpm-pkg' and 'make binrpm-pkg' fail when the kernel source is
read-only. Specifically, when the RPM spec generated by
scripts/package/mkspec is run, KBUILD_SRC happens to be set to the
source location and thus the invocation of 'make headers_install'
fails when an internal call to 'filechk' tries to write a file into
the source tree.
The fix is to clear KBUILD_SRC for the 'make headers_install'
invocation in the spec file, as is already done for the 'make

Its possible to superseed the config file with KCONFIG_CONFIG and have
completely no .config in the tree. The current script is sourcing
.config in every case, so the kernel will never build succesfully. This
patch fixes that issue by sourcing KCONFIG_CONFIG instead.

Device tree source files may now include header files. The intent is
that those header files define/name constants used as part of the DT
bindings. Currently this feature is open to abuse, since any kernel
header file at all can be included, This could allow device tree files
to become dependant on kernel headers files, and thus make them no
longer OS-independent. This would also prevent separating the device
tree source files from the kernel repository.
Solve this by limiting the cpp include path for device tree files to
separate directories.

The devm_request_and_ioremap() function is very useful and helps avoid a
whole lot of boilerplate. However, one issue that keeps popping up is
its lack of a specific error code to determine which of the steps that
it performs failed. Furthermore, while the function gives an example and
suggests what error code to return on failure, a wide variety of error
codes are used throughout the tree.
In an attempt to fix these problems, this patch adds a new function that
drivers can transition to. The devm_ioremap_resource() returns a pointer
to the remapped I/O memory on success or an ERR_PTR() encoded error code
on failure. Callers can check for failure using IS_ERR() and determine
its cause by extracting the error code using PTR_ERR().
devm_request_and_ioremap() is implemented as a wrapper around the new
API and return NULL on failure as before. This ensures that backwards
compatibility is maintained until all users have been converted to the
new API, at which point the old devm_request_and_ioremap() function
should be removed.
A semantic patch is included which can be used to convert from the old
devm_request_and_ioremap() API to the new devm_ioremap_resource() API.
Some non-trivial cases may require manual intervention, though.

ARC relocatable object files contain one/more .gnu.linkonce.arcextmap.*
sections (collated by kernel/vmlinux.lds into .arcextmap in final link).
This section is used by debuggers to display the extension instructions
and need-not be loaded by target (hence !SHF_ALLOC)
The final kernel binary only needs .arcextmap entry in modpost's ignore
list (section_white_list[]). However when building modules, modpost scans
each object file individually, hence tripping on non-aggregated
.gnu.linkonce.arcextmap.* entries as well.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the last of the __dev* markings from the kernel from
a variety of different, tiny, places.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This is
going to be a pain for the merge with different subsystem trees, I know,
but all of the patches included here have been ACKed by their various
subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
it's up to you. The merges should all be trivial, and Stephen has been
doing them all in linux-next for a few weeks now quite easily.
Other than the __dev* marking removals, there's nothing major here, some

If a function has a return value, but its kernel-doc comment doesn't contain a
"Return" section, then emit the following warning:
Warning(file.h:129): No description found for return value of 'fct'
Note: This check emits a lot of warnings at the moment, because many functions
don't have a 'Return' doc section. So until the number of warnings goes
sufficiently down, the check is only performed in verbose mode.

All architectures that use cmd_dtc do so in almost the same way. Create
a central build rule to avoid duplication. The one difference is that
most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
than building the .dtb in the same directory as the .dts file. This
difference will be eliminated arch-by-arch in future patches.
MIPS is the exception here; it already uses the exact same rule as the
new common rule, so the duplicate is removed in this patch to avoid any
conflict. arch/mips changes courtesy of Ralf Baechle.
Update Documentation/kbuild to remove the explicit call to cmd_dtc from
the example, now that the rule exists in a centralized location.

The ncurses library allows for extended colors. The support for extended
colors support depends on wide-character support. ncurses headers
enable extended colors (NCURSES_EXT_COLORS) only when wide-character
support is enabled (NCURSES_WIDECHAR).
The "make menuconfig" uses wide-character ncursesw library, which can be
compiled with wide-character support, but does not define NCURSES_WIDECHAR
and it's using headers without wide-character (and extended colors) support.
This fixes problems with colors on systems with enabled extended colors
(like PLD Linux). Without this patch "make menuconfig" is hard to use.

Emit the magic string that indicates a module has a signature after the
signature data instead of before it. This allows module_sig_check() to
be made simpler and faster by the elimination of the search for the
magic string. Instead we just need to do a single memcmp().
This works because at the end of the signature data there is the
fixed-length signature information block. This block then falls
immediately prior to the magic number.
From the contents of the information block, it is trivial to calculate
the size of the signature data and thus the size of the actual module
data.

Rusty had clearly not actually tested his module signing changes that I
(trustingly) applied as commit e2a666d52b ("kbuild: sign the modules
at install time"). That commit had multiple bugs:
- using "${#VARIABLE}" to get the number of characters in a shell
variable may look clever, but it's locale-dependent: it returns the
number of *characters*, not bytes. And we do need bytes.
So don't use "${#..}" expansion, do the stupid "wc -c" thing instead
(where "c" stands for "bytes", not "characters", despite the letter.
- Rusty had confused "siglen" and "signerlen", and his conversion
didn't set "signerlen" at all, and incorrectly set "siglen" to the
size of the signer, not the size of the signature.
End result: the modified sign-file script did create something that
superficially *looked* like a signature, but didn't actually work at
all, and would fail the signature check. Oops.
Tssk, tssk, Rusty.
But Rusty was definitely right that this whole thing should be rewritten
in perl by somebody who has the perl-fu to do so. That is not me,
though - I'm just doing an emergency fix for the shell script.

If CONFIG_MODULE_SIG is set, then this patch will cause all modules files to
to have signatures added. The following steps will occur:
(1) The module will be linked to foo.ko.unsigned instead of foo.ko
(2) The module will be stripped using both "strip -x -g" and "eu-strip" to
ensure minimal size for inclusion in an initramfs.
(3) The signature will be generated on the stripped module.
(4) The signature will be appended to the module, along with some information
about the signature and a magic string that indicates the presence of the
signature.
Step (3) requires private and public keys to be available. By default these
are expected to be found in files:
signing_key.priv
signing_key.x509
in the base directory of the build. The first is the private key in PEM form
and the second is the X.509 certificate in DER form as can be generated from
openssl:
openssl req \
-new -x509 -outform PEM -out signing_key.x509 \
-keyout signing_key.priv -nodes \
-subj "/CN=H2G2/O=Magrathea/CN=Slartibartfast"
If the secret key is not found then signing will be skipped and the unsigned
module from (1) will just be copied to foo.ko.
If signing occurs, lines like the following will be seen:
LD [M] fs/foo/foo.ko.unsigned
STRIP [M] fs/foo/foo.ko.stripped
SIGN [M] fs/foo/foo.ko
will appear in the build log. If the signature step will be skipped and the
following will be seen:
LD [M] fs/foo/foo.ko.unsigned
STRIP [M] fs/foo/foo.ko.stripped
NO SIGN [M] fs/foo/foo.ko
NOTE! After the signature step, the signed module _must_not_ be passed through
strip. The unstripped, unsigned module is still available at the name on the
LD [M] line. This restriction may affect packaging tools (such as rpmbuild)
and initramfs composition tools.

Provide a script to parse an X.509 certificate and certain pieces of
information from it in order to generate a key identifier to be included within
a module signature.
The script takes the Subject Name and extracts (if present) the
organizationName (O), the commonName (CN) and the emailAddress and fabricates
the signer's name from them:
(1) If both O and CN exist, then the name will be "O: CN", unless:
(a) CN is prefixed by O, in which case only CN is used.
(b) CN and O share at least the first 7 characters, in which case only CN
is used.
(2) Otherwise, CN is used if present.
(3) Otherwise, O is used if present.
(4) Otherwise the emailAddress is used, if present.
(5) Otherwise a blank name is used.
The script emits a binary encoded identifier in the following form:
- 2 BE bytes indicating the length of the signer's name.
- 2 BE bytes indicating the length of the subject key identifier.
- The characters of the signer's name.
- The bytes of the subject key identifier.

Add a simple ASN.1 grammar compiler. This produces a bytecode output that can
be fed to a decoder to inform the decoder how to interpret the ASN.1 stream it
is trying to parse.
Action functions can be specified in the grammar by interpolating:
({ foo })
after a type, for example:
SubjectPublicKeyInfo ::= SEQUENCE {
algorithm AlgorithmIdentifier,
subjectPublicKey BIT STRING ({ do_key_data })
}
The decoder is expected to call these after matching this type and parsing the
contents if it is a constructed type.
The grammar compiler does not currently support the SET type (though it does
support SET OF) as I can't see a good way of tracking which members have been
encountered yet without using up extra stack space.
Currently, the grammar compiler will fail if more than 256 bytes of bytecode
would be produced or more than 256 actions have been specified as it uses
8-bit jump values and action indices to keep space usage down.

"Here are two fixes I intended to send after v3.6-rc7, but failed to do
so. So please pull them for v3.7-rc1 and they will be picked up by
stable.
The first one fixes gcc -x <language> syntax in various build-time
tests, which icecream and possible other gcc wrappers did not
understand (and yes, icecream is going to be fixed as well).
The second one fixes make tar-pkg so that unpacking the tarball does

A section with the name "Example" (case-insensitive) has a special meaning
to kernel-doc. These sections are output using mono-type fonts. However,
leading whitespace is stripped, thus robbing a lot of meaning from this,
as indented code examples will be mangled.
This patch preserves the leading whitespace for "Example" sections. More
accurately, it preserves it for all sections, but removes it later if the
section isn't an "Example" section.

Essentially, the script attempts to close a <programlisting> with a

simply not outputting anything extra when we're dumping pre-formatted

This patch fixes the issue by appending all lines ending in a blackslash

The call if_changed mechanism does not work when the command contains
backslashes. This basically is an issue with lzo and bzip2 compressed
kernels. The compressed binaries do not contain the uncompressed image
size, so these use size_append to append the size. This results in
backslashes in the executed command. With this if_changed always
detects a change in the command and rebuilds the compressed image even
if nothing has changed.
Fix this by escaping backslashes in make-cmd

Pull preparatory patches for user API disintegration from David Howells:
"The patches herein prepare for the extraction of the Userspace API
bits from the various header files named in the Kbuild files.
New subdirectories are created under either include/uapi/ or
arch/x/include/uapi/ that correspond to the subdirectory containing
that file under include/ or arch/x/include/.
The new subdirs under the uapi/ directory are populated with Kbuild
files that mostly do nothing at this time. Further patches will
disintegrate the headers in each original directory and fill in the
Kbuild files as they do it.
These patches also:
(1) fix up #inclusions of "foo.h" rather than <foo.h>.
(2) Remove some redundant #includes from the DRM code.
(3) Make the kernel build infrastructure handle Kbuild files both in
the old places and the new UAPI place that both specify headers
to be exported.
(4) Fix some kernel tools that #include kernel headers during their
build.
I have compile tested this with allyesconfig against x86_64,
allmodconfig against i386 and a scattering of additional defconfigs of
other arches. Prepared for main script

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.
This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.
Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

Plumb the UAPI Kbuilds into the user header installation and checking system.
As the headers are split the entries will be transferred across from the old
Kbuild files to the UAPI Kbuild files.
The changes made in this commit are:
(1) Exported generated files (of which there are currently four) are moved to
uapi/ directories under the appropriate generated/ directory, thus we
get:
include/generated/uapi/linux/version.h
arch/x86/include/generated/uapi/asm/unistd_32.h
arch/x86/include/generated/uapi/asm/unistd_64.h
arch/x86/include/generated/uapi/asm/unistd_x32.h
These paths were added to the build as -I flags in a previous patch.
(2) scripts/Makefile.headersinst is now given the UAPI path to install from
rather than the old path.
It then determines the old path from that and includes that Kbuild also
if it exists, thus permitting the headers to exist in either directory
during the changeover.
I also renamed the "install" variable to "installdir" as it refers to a
directory not the install program.
(3) scripts/headers_install.pl is altered to take a list of source file paths
instead of just their names so that the makefile can tell it exactly
where to find each file.
For the moment, files can be obtained from one of four places for each
output directory:
.../include/uapi/foo/
.../include/generated/uapi/foo/
.../include/foo/
.../include/generated/foo/
The non-UAPI paths will be dropped later.

Pull perf update from Ingo Molnar:
"Lots of changes in this cycle as well, with hundreds of commits from
over 30 contributors. Most of the activity was on the tooling side.
Higher level changes:
- New 'perf kvm' analysis tool, from Xiao Guangrong.
- New 'perf trace' system-wide tracing tool
- uprobes fixes + cleanups from Oleg Nesterov.
- Lots of patches to make perf build on Android out of box, from
Irina Tirdea
- Extend ftrace function tracing utility to be more dynamic for its
users. It allows for data passing to the callback functions, as
well as reading regs as if a breakpoint were to trigger at function
entry.
The main goal of this patch series was to allow kprobes to use
ftrace as an optimized probe point when a probe is placed on an
ftrace nop. With lots of help from Masami Hiramatsu, and going
through lots of iterations, we finally came up with a good
solution.
- Add cpumask for uncore pmu, use it in 'stat', from Yan, Zheng.
- Various tracing updates from Steve Rostedt
- Clean up and improve 'perf sched' performance by elliminating lots
of needless calls to libtraceevent.
- Event group parsing support, from Jiri Olsa
- UI/gtk refactorings and improvements from Namhyung Kim
- Add support for non-tracepoint events in perf script python, from
Feng Tang
- Add --symbols to 'script', similar to the one in 'report', from
Feng Tang.
Infrastructure enhancements and fixes:
- Convert the trace builtins to use the growing evsel/evlist
tracepoint infrastructure, removing several open coded constructs
like switch like series of strcmp to dispatch events, etc.
Basically what had already been showcased in 'perf sched'.
- Add evsel constructor for tracepoints, that uses libtraceevent just
to parse the /format events file, use it in a new 'perf test' to
make sure the libtraceevent format parsing regressions can be more
readily caught.
- Some strange errors were happening in some builds, but not on the
next, reported by several people, problem was some parser related
files, generated during the build, didn't had proper make deps, fix
from Eric Sandeen.
- Introduce struct and cache information about the environment where
a perf.data file was captured, from Namhyung Kim.
- Fix handling of unresolved samples when --symbols is used in
'report', from Feng Tang.
- Add union member access support to 'probe', from Hyeoncheol Lee.
- Fixups to die() removal, from Namhyung Kim.
- Render fixes for the TUI, from Namhyung Kim.
- Don't enable annotation in non symbolic view, from Namhyung Kim.
- Fix pipe mode in 'report', from Namhyung Kim.
- Move related stats code from stat to util/, will be used by the
'stat' kvm tool, from Xiao Guangrong.
- Remove die()/exit() calls from several tools.
- Resolve vdso callchains, from Jiri Olsa
- Don't pass const char pointers to basename, so that we can
unconditionally use libgen.h and thus avoid ifdef BIONIC lines,
from David Ahern
- Refactor hist formatting so that it can be reused with the GTK
browser, From Namhyung Kim
- Fix build for another rbtree.c change, from Adrian Hunter.
- Make 'perf diff' command work with evsel hists, from Jiri Olsa.
- Use the only field_sep var that is set up: symbol_conf.field_sep,
fix from Jiri Olsa.
- .gitignore compiled python binaries, from Namhyung Kim.
- Get rid of die() in more libtraceevent places, from Namhyung Kim.
- Rename libtraceevent 'private' struct member to 'priv' so that it
works in C++, from Steven Rostedt
- Remove lots of exit()/die() calls from tools so that the main perf
exit routine can take place, from David Ahern

- {int,str,rb}list fixes from Suzuki K Poulose
- perf.data header fixes from Namhyung Kim
- Allow user to indicate objdump path, needed in cross environments,
from Maciek Borzecki
- Fix hardware cache event name generation, fix from Jiri Olsa
- Add round trip test for sw, hw and cache event names, catching the
problem Jiri fixed, after Jiri's patch, the test passes
successfully.
- Clean target should do clean for lib/traceevent too, fix from David
Ahern
- Check the right variable for allocation failure, fix from Namhyung
Kim
- Set up evsel->tp_format regardless of evsel->name being set
already, fix from Namhyung Kim
- Oprofile fixes from Robert Richter.
- Remove perf_event_attr needless version inflation, from Jiri Olsa
- Introduce libtraceevent strerror like error reporting facility,
from Namhyung Kim
- Add pmu mappings to perf.data header and use event names from cmd
line, from Robert Richter
- Fix include order for bison/flex-generated C files, from Ben
Hutchings
- Build fixes and documentation corrections from David Ahern
- Assorted cleanups from Robert Richter
- Let O= makes handle relative paths, from Steven Rostedt
- perf script python fixes, from Feng Tang.
- Initial bash completion support, from Frederic Weisbecker
- Allow building without libelf, from Namhyung Kim.
- Support DWARF CFI based unwind to have callchains when %bp based
unwinding is not possible, from Jiri Olsa.
- Symbol resolution fixes, while fixing support PPC64 files with an
.opt ELF section was the end goal, several fixes for code that
handles all architectures and cleanups are included, from Cody
Schafer.
- Assorted fixes for Documentation and build in 32 bit, from Robert
Richter
- Cache the libtraceevent event_format associated to each evsel
early, so that we avoid relookups, i.e. calling pevent_find_event
repeatedly when processing tracepoint events.
[ This is to reduce the surface contact with libtraceevents and
make clear what is that the perf tools needs from that lib: so
far parsing the common and per event fields. ]
- Don't stop the build if the audit libraries are not installed, fix
from Namhyung Kim.
- Fix bfd.h/libbfd detection with recent binutils, from Markus
Trippelsdorf.
- Improve warning message when libunwind devel packages not present,
from Jiri Olsa"

Merge tag 'localmodconfig-v3.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-kconfig
Pull localmodconfig fixes from Steven Rostedt:
"Bill Pemberton added some changes to make streamline-config.pl work
again as a stand-alone tool (outside of make localmodconfig).
Also, he added a couple of updates to make the code be more "Perl
proper".
Added last minute fix to localyesconfig, that was the same as
localmodconfig since v3.2, due to a change in the makefiles."
* tag 'localmodconfig-v3.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-kconfig:
localmodconfig: Fix localyesconfig to set to 'y' not 'm'
localmodconfig: Use my variable for loop in streamline_config.pl
localmodconfig: Use 3 parameter open in streamline_config.pl
localmodconfig: Rework find_config in streamline_config.pl
localmodconfig: Set default value for ksource in streamline_config.pl
The kbuild target 'localyesconfig' has been same as 'localmodconfig'
since the commit 50bce3e "kconfig/streamline_config.pl: merge
local{mod,yes}config". The commit expects this script generates
different configure depending on target, but it was not yet implemented.
So I added code that sets to 'yes' when target is 'localyesconfig'.

This updates scripts/dtc to commit 317a5d9 "dtc: zero out new label
objects" from git://git.jdl.com/software/dtc.git.
This adds features such as:
* /bits/ syntax for cell data.
* Math expressions within cell data.
* The ability to delete properties or nodes.
* Support for #line directives in the input file, which allows the use of
cpp on *.dts.
* -i command-line option (/include/ path)
* -W/-E command-line options for error/warning control.
* Removal of spew to STDOUT containing the filename being compiled.
* Many additions to the libfdt API.
