Steven Rostedt (Red Hat) a50bd43935 ftrace/scripts: Have recordmcount copy the object file
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.

Russell King dd39a26538 scripts: recordmcount: break hardlinks
recordmcount edits the file in-place, which can cause problems when
using ccache in hardlink mode.  Arrange for recordmcount to break a
hardlinked object.

Valentin Rothberg 1b2c841467 checkkconfigsymbols.py: find similar symbols
Add support to find string-similar symbols.  When option --sim SYM is
specified, checkkconfigsymbols.py will print at most 10 symbols defined
in Kconfig that are string similar to SYM in the following format:
    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
    Referencing files: $COMMA_SEPARATED_LIST_OF_FILES
    Similar symbols: $COMMA_SEPARATED_LIST_OF_SYMBOLS
    [Optional with '--find']
    Commits changing symbol:
        - $COMMIT_1_HASH ("$COMMIT_1_MESSAGE")
        - $COMMIT_2_HASH ("$COMMIT_2_MESSAGE")
            or
        - no commit found

Lorenzo Colitti fb1770aa78 arch: um: fix error when linking vmlinux.

Michal Marek cf4f21938e kbuild: Allow to specify composite modules with modname-m
This allows to write

  drm-$(CONFIG_AGP) += drm_agpsupport.o

without having to handle CONFIG_AGP=y vs. CONFIG_AGP=m. Only support
this syntax for modules, since built-in code depending on something
modular cannot work and init/Makefile actually relies on the current
semantics. There are a few drivers which adapted to the current
semantics out of necessity; these are fixed to also work when the
respective subsystem is modular.

Riku Voipio 4b63f60313 package Makefile: fix perf-tar targets when outdir is set
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.

The regex to strip single line #define's in enumerations depends on the
fact that the defines are still stored on separate lines. But the

example (e.g., --nogit is mentioned as a default option), but they aren't

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'.

Linus Torvalds 22402cd0af 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:
 ----------------------------
 
  o Module globbing. You can now filter function tracing to several
    modules. # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov)
 
  o 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.
 
  o Trace options are now per instance (although some of the tracer specific
    options are global)

Merge tag 'trace-v4.4' of 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"

Linus Torvalds 0280d1a099 sound updates for 4.4-rc1
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 highlight is 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

Li Bin 2ee8a74f2a recordmcount: arm64: Replace the ignored mcount call into nop
By now, the recordmcount only records the function that in
following sections:
.text/.ref.text/.sched.text/.spinlock.text/.irqentry.text/
.kprobes.text/.text.unlikely

For the function that not in these sections, the call mcount
will be in place and not be replaced when kernel boot up. And
it will bring performance overhead, such as do_mem_abort (in
.exception.text section). This patch make the call mcount to
nop for this case in recordmcount.

Thiago Macieira 588446a847 Use pkg-config to find Qt 4 and 5 instead of direct qmake
The Qt Project recommendation is that there should always be a "qmake"
binary and it should never be renamed. If it's necessary to handle
multiple Qt versions, the Qt Project recommends using qtchooser.

Unfortunately, some distros do not follow the recommendation, so we
would need to check qmake-qt4, qmake-qt5, etc. So, instead, let's try
pkg-config.

Ben Hutchings 63a478fbc0 deb-pkg: Add automatic support for armhf architecture
The Debian armhf architecture uses the ARM EABI hard-float variant,
whereas armel uses the soft-float variant.  Although the kernel
doesn't use FP itself, CONFIG_VFP must be enabled to support
hard-float userland and will probably be disabled when supporting a
soft-float userland.  So set the architecture to armhf by default when
CONFIG_AEABI and CONFIG_VFP are both enabled.

This effectively reverts 932058a5d5 ("coccinelle: misc: semantic patch
to delete overly complex return code processing").

There can be both symmetry and readability reasons for not wanting to do
the final function call as part of the return statement and to maintain
a clear separation of success and error paths.

Since this is in no way mandated by the coding standard, let's just
remove this semantic patch to avoid having "clean up" patches being

David Howells 4adc605edc KEYS: Provide a script to extract a module signature
The supplied script takes a signed module file and extracts the tailmost
signature (there could theoretically be more than one) and dumps all or
part of it or the unsigned file to stdout.

Call as:

	scripts/extract-module-sig.pl -[0adnks] module-file >out

where the initial flag indicates which bit of the signed file you want dumping
to stdout:

 (*) "-0".  Dumps the unsigned data with the signature stripped.

 (*) "-a".  Dumps all of the signature data, including the magic number.

 (*) "-d".  Dumps the signature information block as a sequence of decimal
     	    numbers in text form with spaces between (crypto algorithm type,
     	    hash type, identifier type, signer's name length, key identifier
     	    length and signature length).

 (*) "-n".  Dumps the signer's name contents.

 (*) "-k".  Dumps the key identifier contents.

 (*) "-s".  Dumps the cryptographic signature contents.

In the case that the signature is a PKCS#7 (or CMS) message, -n and -k will
print a warning to stderr and dump nothing to stdout, but will otherwise
complete okay; the entire PKCS#7/CMS message will be dumped by "-s"; and "-d"
will show "0 0 2 0 0 <pkcs#7-msg-len>".

The supplied script takes a vmlinux file - and if necessary a System.map

Call as:

    ./scripts/extract-sys-certs vmlinux certs

if vmlinux contains symbols and:

    ./scripts/extract-sys-certs -s System.map vmlinux certs

if it does not.

It prints something like the following to stdout:

	Have 27 sections
	No symbols in vmlinux, trying System.map
	Have 80088 symbols
	Have 1346 bytes of certs at VMA 0xffffffff8201c540
	Certificate list in section .init.data
	Certificate list at file offset 0x141c540

If vmlinux contains symbols then that is used rather than System.map - even
if one is given.

Alexander Kapshuk 1920c298e7 ver_linux: proc/modules, limit text processing to 'sed'
This patch is more of a personal preference, rather than a fix for a problem.

The current implementation used a combination of both 'cat' and 'sed'
to generate an unsorted list of kernel modules separated by while space.

The proposed implementation uses 'sort' and 'sed' to generate a sort
list of kernel modules separated by while space.

Riku Voipio 8d740a37b9 builddeb: remove debian/files before build
Commit 3716001bcb ("deb-pkg: add source package") added the ability to
create a debian changelog file.  This exposed that previously the
builddeb script hasn't cleared debian/files between builds.

As debian/files keeps accumulating entries, the changes file will end up
growing indefinelty.  With outdated entries in debian/files, builddeb
script will exit with failure.  This regression impacts those who use
"make deb-pkg" target to build kernel into a .deb package and never use
"make mrproper" or other means to clean kernel tree from generated
directories.

To fix the regression, remove debian/files before starting build and in
the generated clean rule.

Michael Ellerman bd960f0983 scripts/kconfig/Makefile: Fix KBUILD_DEFCONFIG check when building with O=
My recent commit d2036f30cf ("scripts/kconfig/Makefile: Allow
KBUILD_DEFCONFIG to be a target"), contained a bug in that when it
checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to
the path.

This causes the build to fail when building out of tree (with O=), and
when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will
fail to find the 'defconfig' file, because we look in the build
directory not $(srctree), and so we will call Make again with
'defconfig' as the target. From there we loop infinitely calling 'make
defconfig' again and again.

The fix is simple, we need to look for the file under $(srctree).

All make targets support $KCONFIG_CONFIG because they

Previously this script broke in two different code paths,
one for targets like kvmconfig (which use merge_config.sh -m
then call a target that respects KCONFIG_CONFIG) and one for
direct use of the script without -m, which called make rules
that edit KCONFIG_CONFIG but verified a different file.

Andrey Ryabinin 39d114ddc6 arm64: add KASAN support
This patch adds arch specific code for kernel address sanitizer
(see Documentation/kasan.txt).

1/8 of kernel addresses reserved for shadow memory. There was no
big enough hole for this, so virtual addresses for shadow were
stolen from vmalloc area.

At early boot stage the whole shadow region populated with just
one physical page (kasan_zero_page). Later, this page reused
as readonly zero shadow for some memory that KASan currently
don't track (vmalloc).
After mapping the physical memory, pages for shadow memory are
allocated and mapped.

Functions like memset/memmove/memcpy do a lot of memory accesses.
If bad pointer passed to one of these function it is important
to catch this. Compiler's instrumentation cannot do this since
these functions are written in assembly.
KASan replaces memory functions with manually instrumented variants.
Original functions declared as weak symbols so strong definitions
in mm/kasan/kasan.c could replace them. Original functions have aliases
with '__' prefix in name, so we could call non-instrumented variant
if needed.
Some files built without kasan instrumentation (e.g. mm/slub.c).
Original mem* function replaced (via #define) with prefixed variants
to disable memory access checks for such files.

Setting CONFIG_SECTION_MISMATCH_WARN_ONLY=y causes these warnings to be

Michael Ellerman d2036f30cf scripts/kconfig/Makefile: Allow KBUILD_DEFCONFIG to be a target
Arch Makefiles can set KBUILD_DEFCONFIG to tell kbuild the name of the
defconfig that should be built by default.

However currently there is an assumption that KBUILD_DEFCONFIG points to
a file at arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG).

We would like to use a target, using merge_config, as our defconfig, so
adapt the logic in scripts/kconfig/Makefile to allow that.

To minimise the chance of breaking anything, we first check if
KBUILD_DEFCONFIG is a file, and if so we do the old logic. If it's not a
file, then we call the top-level Makefile with KBUILD_DEFCONFIG as the
target.

David Howells 283e8ba2df MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too old
The sign-file.c program actually uses CMS rather than PKCS#7 to sign a file
since that allows the target X.509 certificate to be specified by
subjectKeyId rather than by issuer + serialNumber.

However, older versions of the OpenSSL crypto library (such as may be found
in CentOS 5.11) don't support CMS.  Assume everything prior to
OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case.

Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so
give an error from the sign-file script if the caller requests anything
other than SHA1.

The compiler gives the following error with an OpenSSL crypto library
that's too old:

  HOSTCC  scripts/sign-file
scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or directory

The "highlight" code is very sensible to the order of the hash keys,

faulty DocBook entries like:

Sorting the result is not enough some times (as it's deterministic but
we can't control it).
We should use an array for that job, so we can guarantee that the order
of the regex execution on dohighlight is correct.

 are saying @function() when "function" is not a parameter.  But this makes
 things better than they were before, so...]

Danilo Cesar Lemes de Paula 23aebb3c05 scripts/kernel-doc: Processing -nofunc for functions only
Docproc processes the EXPORT_SYMBOL(f1) macro and uses -nofunc f1 to
avoid duplicated documentation in the next call.
It works for most of the cases, but there are some specific situations
where a struct has the same name of an already-exported function.

Current kernel-doc behavior ignores those structs and does not add them
to the final documentation. This patch fixes it.

This is unusual, the only case I've found is the drm_modeset_lock
(function and struct) defined in drm_modeset_lock.h and
drm_modeset_lock.c. Considering this, it should only affect the DRM
documentation by including struct drm_modeset_lock to the final Docbook.
