HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the
default high-pass filter in some "safer" range, which results in the
very soft tone from the built-in speakers in contrast to Windows.
Also, the mute LED control is missing, since 92HD95 codec still has no
HP-specific fixups for GPIO setups.
This patch adds these missing features: the HPF is adjusted by the
vendor-specific verb, and the LED is set up from a DMI string (but
with the default polarity = 0 assumption due to the incomplete BIOS on
the given machine).

race condition that happens between enabling/disabling syscall tracepoints

It also includes a patch to introduce a new macro for the TRACE_EVENT()

any variable into a trace event, but with the addition of setting the
"is signed" attribute, the check causes anything but a primitive variable
to fail to compile. That is, structs and unions can't be used as they
once were. When the "is signed" check was introduce there were only
primitive variables being recorded. But that will change soon and it
was reported that __field() causes build failures.
To solve the __field() issue, __field_struct() is introduced to allow
trace_events to be able to record complex types too.

The commit 71ec7c55ed introduced the magic symbol ".TOC." for ELFv2 ABI.
This symbol is built manually and has no CRC value computed. A zero value
is put in the CRC section to avoid modpost complaining about a missing CRC.
Unfortunately, this breaks the kernel module loading when the kernel is
relocated (kdump case for instance) because of the relocation applied to
the kcrctab values.
This patch compute a CRC value for the TOC symbol which will match the one
compute by the kernel when it is relocated - aka '0 - relocate_start' done in
maybe_relocated called by check_version (module.c).

In commit 27f4488872 "Add OPAL takeover from PowerVM" we added support
for "takeover" on OPAL v1 machines.
This was a mode of operation where we would boot under pHyp, and query
for the presence of OPAL. If detected we would then do a special
sequence to take over the machine, and the kernel would end up running
in hypervisor mode.
OPAL v1 was never a supported product, and was never shipped outside
IBM. As far as we know no one is still using it.
Newer versions of OPAL do not use the takeover mechanism. Although the
query for OPAL should be harmless on machines with newer OPAL, we have
seen a machine where it causes a crash in Open Firmware.
The code in early_init_devtree() to copy boot_command_line into cmd_line
was added in commit 817c21ad9a "Get kernel command line accross OPAL
takeover", and AFAIK is only used by takeover, so should also be

NFS_INO_INVALID_DATA cannot be ignored, even if we have a delegation.
We're still having some problems with data corruption when multiple
clients are appending to a file and those clients are being granted
write delegations on open.
To reproduce:
Client A:
vi /mnt/`hostname -s`
while :; do echo "XXXXXXXXXXXXXXX" >>/mnt/file; sleep $(( $RANDOM % 5 )); done
Client B:
vi /mnt/`hostname -s`
while :; do echo "YYYYYYYYYYYYYYY" >>/mnt/file; sleep $(( $RANDOM % 5 )); done
What's happening is that in nfs_update_inode() we're recognizing that
the file size has changed and we're setting NFS_INO_INVALID_DATA
accordingly, but then we ignore the cache_validity flags in
nfs_write_pageuptodate() because we have a delegation. As a result,
in nfs_updatepage() we're extending the write to cover the full page
even though we've not read in the data to begin with.

vdso2c was checking for various types of relocations to detect when
the vdso had undefined symbols or was otherwise dependent on
relocation at load time. Undefined symbols in the vdso would fail if
accessed at runtime, and certain implementation errors (e.g. branch
profiling or incorrect symbol visibilities) could result in data
access through the GOT that requires relocations. This could be
as simple as:
extern char foo;
return foo;
Without some kind of visibility control, the compiler would assume
that foo could be interposed at load time and would generate a
relocation.
x86-64 and x32 (as opposed to i386) use explicit-addent (RELA) instead
of implicit-addent (REL) relocations for data access, and vdso2c
forgot to detect those.
Whether these bad relocations would actually fail at runtime depends
on what the linker sticks in the unrelocated references. Nonetheless,
these relocations have no business existing in the vDSO and should be
fixed rather than silently ignored.
This error could trigger on some configurations due to branch
profiling. The previous patch fixed that.

DISABLE_BRANCH_PROFILING turns off branch profiling (i.e. a
redefinition of 'if'). Branch profiling depends on a bunch of
kernel-internal symbols and generates extra output sections, none of
which are useful or functional in the vDSO.
It's currently turned off for vclock_gettime.c, but vgetcpu.c also
triggers branch profiling, so just turn it off in the makefile.
This fixes the build on some configurations: the vdso could contain
undefined symbols, and the fake section table overflowed due to
ftrace's added sections.

"of: Ensure unique names without sacrificing determinism"
caused a boot failure regression on the Integrator machines.
The problem is probably caused by fiddling too much with
the device tree population in the OF init function, such
as passing the SoC bus device as parent when populating
the device tree.
This patch fixes the problem by:
- Avoiding to explicitly look up the tree root
- Look up devices needed before device population from
the match only, passing NULL as root
- Passing NULL as root and parent when calling
of_platform_populate()
After this the Integrators boot again. Tested on
Integrator/AP and Integrator/CP.
