Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target

Rather than hardcoding ".config" use conf_get_configname(), which also
respects the environment variable KCONFIG_CONFIG.
This fixes "make silentoldconfig" when KCONFIG_CONFIG is used and also
suggests the given filename for "Load" and "Save as" in qconf.

The Debian packaging scripts created by the deb-pkg target do not pass
on the standard Debian maintainer script parameters to hook scripts,
which means that those scripts cannot tell whether they are being called

As there are several variantions in how hook scripts are called from

That check already ignored sections named ".comment" - but SUSE store

The powerpc kernel always requires an Open Firmware like device tree
to supply device information. On systems without OF, this comes from
a flattened device tree blob. This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel. Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM). To do this it uses the libfdt library.
Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).
However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs. A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.
The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.

When you put
.section ".foo"
in an assembly file instead of
.section "foo", "ax"
, one of the possible symptoms is that modpost will see an
ld-generated section name ".foo.1" in section_rel() or section_rela().
But this heuristic has two problems: it will miss a bad section that
has no relocations, and it will incorrectly flag many gcc-generated
sections as bad when compiling with -ffunction-sections
-fdata-sections.
On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one:
WARNING: crypto/cryptd.o (.text.T.349): unexpected section name.
So instead of checking whether the section name matches a particular

While building the kernel, we end-up calling modpost with -K and -M
options for the same file (Modules.markers). This is resulting in
modpost's main function calling read_markers() and then write_markers() on
the same file.
We then have read_markers() mmap'ing the file, and writer_markers()
opening that same file for writing.
The issue is that read_markers() exits without munmap'ing the file and is
as a matter holding a reference on Modules.markers. When write_markers()
is opening that very same file for writing, we still have a reference on
it and cygwin (Windows?) is then making fopen() fail with EPERM.
Calling release_file() before exiting read_markers() clears that reference
(and memory leak) and fopen() then succeeds.
Tested on both cygwin (1.3.22) and Linux. Also ran modpost within
valgrind on Linux to make sure that the munmap'ed file was not accessed
after read_markers()

Following patch introduce support for setting options
to gcc that has effect for current directory and all
subdirectories.
The typical use case are an architecture or a subsystem that
decide to cover all files with -Werror.
Today alpha, mips and sparc uses -Werror in almost all their
Makefile- with subdir-ccflag-y it is now simpler to do so
as only the top-level directories needs to be covered.
Likewise if we decide to cover a full subsystem such
as net/ with -Werror this is done by adding a single
line to net/Makefile.

When gen_initramfs_list is used to generate make dependencies, it
includes symbolic links, for which make tracks the link target. Any
change to that target will cause an initramfs rebuild, even if the
symlink points to something outside of the initramfs directory.
If the target happens to be /tmp, the rebuild occurs for each kernel
build, since gen_initramfs_list uses mktemp...
Proposed way to fix it is to omit symbolic links from generated
dependencies, but this has a small drawback: changing perm/owner on a
symlink will go unnoticed.

=====
In latest 2.6.29 "make update-po-config" fails at msguniq invocation
with an "invalid control sequence" error.
The offending string is the following, and it's located in
drivers/staging/panel/Kconfig:72:
"'\e[L' which are specific to the LCD, and a few ANSI codes. The"
looks to me like gettext expects strings in printf format, so in
this case it thinks "\e" is a control sequence but doesn't recognise
it as a valid one.
A valid solution would be to tell kxgettext to automatically
escape this kind of strings in the */config.pot he produces, so that
msguniq would not complain.

With CONFIG_MODVERSIONS, we version 'struct module' using a dummy
export, but other things matter too:
1) 'struct modversion_info' determines the layout of the __versions section,
2) 'struct kernel_param' determines the layout of the __params section,
3) 'struct kernel_symbol' determines __ksymtab*.
4) 'struct marker' determines __markers.
5) 'struct tracepoint' determines __tracepoints.
So we rename 'struct_module' to 'module_layout' and include these in
the signature. Now it's general we can add others later on without
confusion.

This patch combines Greg Bank's dprintk() work with the existing dynamic
printk patchset, we are now calling it 'dynamic debug'.
The new feature of this patchset is a richer /debugfs control file interface,
(an example output from my system is at the bottom), which allows fined grained
control over the the debug output. The output can be controlled by function,
file, module, format string, and line number.
for example, enabled all debug messages in module 'nf_conntrack':
echo -n 'module nf_conntrack +p' > /mnt/debugfs/dynamic_debug/control
to disable them:
echo -n 'module nf_conntrack -p' > /mnt/debugfs/dynamic_debug/control
A further explanation can be found in the documentation patch.

Now platform_device is being widely used on SoC processors where the
peripherals are attached to the system bus, which is simple enough.
However, silicon IPs for these SoCs are usually shared heavily across
a family of processors, even products from different companies. This
makes the original simple driver name based matching insufficient, or
simply not straight-forward.
Introduce a module id table for platform devices, and makes it clear
that a platform driver is able to support some shared IP and handle
slight differences across different platforms (by 'driver_data').
Module alias is handled automatically when a MODULE_DEVICE_TABLE()
is defined.
To not disturb the current platform drivers too much, the matched id
entry is recorded and can be retrieved by platform_get_device_id().

'make randconfig' uses glibc's rand function, and the seed of
that PRNG is set via:
srand(time(NULL));
But 'time()' only increases once every second - freezing the
randconfig result within a single second.
My Nehalem testbox does randconfig much faster than 1 second
and i have a few scripts that do 'randconfig until condition X'
loops.
Those scripts currently waste a lot of CPU time due to randconfig
changing its seed only once per second currently.
Change the seed to be micrseconds based. (I checked the statistical
spread of the seed - the now.tv_sec*now.tv_usec multiplication
there further improves it.)

Ingo Molnar reported that 'make randconfig' was not covering
choice blocks properly, resulting in certain config options
being left out of randconfig testing altogether.
With the following patch we:
- properly randomize choice value for normal choice blocks
- properly randomize for multi choice blocks
- added several comments to explain what is going on
The root cause of the bug was that SYMBOL_VALID was set on the
symbol representing the choice block so clearing this did
the trick initially.
But testign revealed a few more issues that is now fixed.

Impact: bugfix, output more reliable symbol lookup result
Debug tools(dump_stack(), ftrace...) are like to print out symbols.
But it is always print out the first aliased symbol.(Aliased symbols
are symbols with the same address), and the first aliased symbol is
sometime not proper.
# echo function_graph > current_tracer
# cat trace
......
1) 1.923 us | select_nohz_load_balancer();
1) + 76.692 us | }
1) | default_idle() {
1) ==========> | __irqentry_text_start() {
1) 0.000 us | native_apic_mem_write();
1) | irq_enter() {
1) 0.000 us | idle_cpu();
1) | tick_check_idle() {
1) 0.000 us | tick_check_oneshot_broadcast();
1) | tick_nohz_stop_idle() {
......
It's very embarrassing, it ouputs "__irqentry_text_start()",
actually, it should output "smp_apic_timer_interrupt()".
(these two symbol are the same address, but "__irqentry_text_start"
is deemed to the first aliased symbol by scripts/kallsyms)
This patch puts symbols like "__irqentry_text_start" to the second
aliased symbols. And a more proper symbol name becomes the first.
Aliased symbols mostly come from linker script. The solution is
guessing "is this symbol defined in linker script", the symbols
defined in linker script will not become the first aliased symbol.
And if symbols are found to be equal in this "linker script provided"
criteria, symbols are sorted by the number of prefix underscores.

Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source
tree under SCM. This is due to KERNELRELEASE being different when the initial make
is run and when make is run from rpmbuild.
mkspec creates kernel.spec using KERNELRELEASE:
<mkspec>
echo "%files"
echo '%defattr (-, root, root)'
echo "%dir /lib/modules"
echo "/lib/modules/$KERNELRELEASE"
echo "/lib/firmware"
echo "/boot/*"
echo ""
</mkspec>
When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any
additional version info from SCM. Next, the srctree is tarred up and SCM
information is excluded.
rpmbuild reruns make and in the process generates a new include/config/kernel.release
and thus a new KERNELRELEASE. However this time the SCM information is gone so
KERNELRELEASE no longer has the additional version information. When "make modules_install"
runs, it uses the new KERNELRELEASE value to determine where to install the modules.
This conflicts with where the spec file assumes they are going because of the
mis-matching KERNELRELEASE versions.
