If a text section starts out with a data blob before the first
function start label, disassembly parsing doing in recordmcount.pl
gets confused on powerpc, leading to creation of corrupted module
objects.
This was not a problem so far since the compiler would never create
such text sections. However, this has changed with a recent change
in GCC 6 to support distances of > 2GB between a function and its
assoicated TOC in the ELFv2 ABI, exposing this problem.
There is already code in recordmcount.pl to handle such data blobs
on the sparc64 platform. This patch uses the same method to handle
those on powerpc as well.

Introduction of __smp barriers cleans up a bunch of duplicate code, but
it gives people an additional handle onto a "new" set of barriers - just
because they're prefixed with __* unfortunately doesn't stop anyone from
using it (as happened with other arch stuff before.)
Add a checkpatch test so it will trigger a warning.

Unsigned expressions cannot be lesser than zero. Presence of comparisons
'unsigned (<|<=|>|>=) 0' often indicates a bug, usually wrong type of variable.
The patch beside finding such comparisons tries to eliminate false positives,
mainly by bypassing range checks.
gcc can detect such comparisons also using -Wtype-limits switch, but it warns
also in correct cases, making too much noise.

Ideally, a kernel compile with W=1 enabled should complete cleanly;
however, when we run one currently we are presented with ~25k warnings.
'sign-compare' accounts for ~22k of those ~25k.
In this patch we're demoting 'sign-compare' warnings to W=2, with a view
to fixing the remaining 3k W=1 warnings required for a clean build.
Arnd adds:
"As per our discussion, I'd add that this was inadvertedly introduced
by Behan when he moved the clang specific warnings into an ifdef block
and did not notice that -Wsign-compare was interpreted by both gcc
and clang.
Earlier, it was introduced in just the same way by Jan-Simon as part
of 3d3d6b847420 ("kbuild: LLVMLinux: Adapt warnings for compilation
with clang")."

On Fedora 23, ld --version outputs:

But ld-version.sh fails to parse this, so e.g. mips build fails to

The emacs rules were constantly lagging behind the exuberant ones. Use a
single set of rules for both, to make the script easier to maintain.
The language understood by both tools is basic regular expression with
some limitations, which are documented in a comment. To be able to store
the rules in an array and easily iterate over it, the script requires
bash now. In the exuberant case, the change fixes some false matches in
<linux/page-flags.h> and also some too greedy matches in the arguments
of the DECLARE_*/DEFINE_* macros. In the emacs case, several previously
not working rules are matching now. Tested with these versions of the
tools:

Apparently, ctags applies the rules before deleting comments:
ctags: Warning: include/linux/completion.h:22: null expansion of name pattern "\2"

This allows to apply the same patters to both source and header files.
The effect is mostly visible in the case of DECLARE_BITMAP, but there
are small gains all over the place. There is also lots of random changes
in the diff, I believe this is simply because there are still lots of
unexpanded macros in the code and the C and C++ parsers fail and recover
at different points. Also, qconf.h is parsed as C, but that's a
negligible regression.

The ld-version.sh script doesn't handle versions with large (>= 10) 3rd
version components, because the 2nd component is only multiplied by 10
times that of the 3rd component.
For example the following version string:
GNU ld (Codescape GNU Tools 2015.06-05 for MIPS MTI Linux) 2.24.90
gives a bogus version number:
20000000
+ 2400000
+ 900000 = 23300000
Breakage, confusion and mole-whacking ensues.
Increase the multipliers of the first two version components by a factor
of 10 to give space for a 3rd components of up to 99, and update the
sole user of ld-ifversion (MIPS VDSO) accordingly.

Russell King found that he had weird side effects when compiling the kernel
with hard linked ccache. The reason was that recordmcount modified the
kernel in place via mmap, and when a file gets modified twice by
recordmcount, it will complain about it. To fix this issue, Russell wrote a
patch that checked if the file was hard linked more than once and would
unlink it if it was.
Linus Torvalds was not happy with the fact that recordmcount does this in
place modification. Instead of doing the unlink only if the file has two or
more hard links, it does the unlink all the time. In otherwords, it always
does a copy if it changed something. That is, it does the write out if a
change was made.

Add support to find string-similar symbols. When option --sim SYM is

Similar symbols: $COMMA_SEPARATED_LIST_OF_SYMBOLS
Note, if no similar symbols are found it is indicated as follows:
Similar symbols: no similar symbols found
Since the implemented functionality is also useful when searching the
entire source or when diffing two commits, a list of similar symbols is
printed unconditionally with the other data. In order to make the
output more readable, the format now looks as follows:
$UNDEFINED_SYMBOL

building with $srctree != $objtree, perf-tar-* targets fail
to read the MANIFEST file and add the PERF-VERSION-FILE needed
by out-of-tree builds. The build errors and an incorrect tar is created:
$ make O=build-x86 perf-targz-src-pkg
TAR
cat: ../tools/perf/MANIFEST: No such file or directory
tar: perf-4.1.0-rc8/PERF-VERSION-FILE: Cannot stat: No such file or
dir..
tar: Exiting with failure status due to previous errors
Kbuild sets objtree to "." and srctree to ".." The command to output
MANIFEST becomes:
$(cd ..; echo $(cat ../tools/perf/MANIFEST))
Without MANIFEST, the entire kernel source tree is added to the perf
source tarball. The *correct* fix is to keep the cd and remove srctree
from cat command line since MANIFEST has wildcards that fail to expand
working directory isn't srctree.
Second, PERF-VERSION-FILE gets not added, because in-tree build path is
hardcoded to Makefile:
util/PERF-VERSION-GEN ../../$(perf-tar)/ 2>/dev/null)
The PERF-VERSION-GEN needs to be run from tools/perf directory,
and the output directory needs to be changed from relative to
to absolute. This can be achieved using the $(CURDIR) variable.
Also remove the error redirect to /dev/null which hid the error.

Global and static variables don't need to be initialized to 0.
There is already a test for this but the output message doesn't
mention booleans initialized to false.
Improve the output message and the test by adding various forms
with possible specific integer types and possible multiple zeros.
Miscellanea:
o Use a variable to hold the possible 0 test

Including BUG and stack dumps in commit logs makes checkpatch produce some
false positive warning messages.
checkpatch has multiple types of false positives:
o Commit message lines > 75 chars
o Stack dump address are mistaken for git commit IDs
o Link: and Fixes: lines are allowed to be > 75 chars.
o Fixes: style doesn't require ("<commit_description>")
parentheses and double quotes like other uses of
git commit ID and description.
Fix these.
Miscellanea:
o Move the test for checking $commit_log_possible_stack_dump
above the test for a long line commit message
o Add test for hex address surrounded by square or angle brackets

Many flag options are boolean and support both a positive and a negative
invocation from the command line. Some of these are even mentioned by
example (e.g., --nogit is mentioned as a default option), but they aren't
explicitly mentioned in the list of options. It happens that some of
these are pretty important, as they are default-on, and to turn them off,
you have to know about the --no-foo version.
Rather than clutter the whole help text with bracketed '--[no]foo', let's
just mention the general rule, a la 'man gcc'.

I really haven't used this option much myself, so feel free to improve on
the documentation for it. I just noticed it while inspecting this script

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracking updates from Steven Rostedt:
"Most of the changes are clean ups and small fixes. Some of them have
stable tags to them. I searched through my INBOX just as the merge
window opened and found lots of patches to pull. I ran them through
all my tests and they were in linux-next for a few days.
Features added this release:
----------------------------
- Module globbing. You can now filter function tracing to several
modules. # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov)
- Tracer specific options are now visible even when the tracer is not
active. It was rather annoying that you can only see and modify
tracer options after enabling the tracer. Now they are in the
options/ directory even when the tracer is not active. Although
they are still only visible when the tracer is active in the
trace_options file.
- Trace options are now per instance (although some of the tracer
specific options are global)
- New tracefs file: set_event_pid. If any pid is added to this file,
then all events in the instance will filter out events that are not
part of this pid. sched_switch and sched_wakeup events handle next
and the wakee pids"

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"Here is the first batch of updates for sound system on 4.4-rc1.
Again at this time, the update looks fairly calm; no big changes in
either ALSA core or ASoC infrastructures, rather all small cleanups,
in addition to the new stuff as usual.
The biggest changes are about Firewire sound devices. It gained lots
of new device support, and MIDI functionality. Also there are updates
for a few still working-in-progress stuff (topology API and ASoC
skylake), too. But overall, this update should give no big surprise.
Some highlights are below:
Core:
- A few more Kconfig items for tinification; it's marked as EXPERT,
so normal user should't be bothered :)
- Refactoring with a new PCM hw_constraint helper
- Removal of unused transfer_ack_{begin,end} PCM callbacks
Firewire:
- Restructuring of code subtree, lots of refactoring
- Support AMDTP variants
- New driver for Digidesign 002/003 family
- Adds support for TASCAM FireOne to ALSA OXFW driver
- Add MIDI support to TASCAM and Digi00x devices
HD-Audio:
- Automated modalias generation for codec drivers, finally
- Improvement on heuristics for setting mixer name
- A few fixes for longstanding bugs on Creative CA0132 cards
- Addition of audio rate callback with i915 communication
- Fix suspend issue on recent Dell XPS
- Intel Lewisburg controller support
ASoC:
- Updates to the topology userspace interface
- Big updates to the Renesas support (rcar)
- More updates for supporting Intel Sky Lake systems
- New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip
S/PDIF, and Atmel class D amplifier
USB-Audio:
- A fix for newer Roland MIDI devices
- Quirks and workarounds for Zoom R16/24 device
Misc:
- A few fixes for some old Cirrus CS46xx PCI sound boards
- Yet another fixes for some old ESS Maestro3 PCI sound boards"
