Pull tracing fixlet from Steven Rostedt:
 "Joel Fernandes asked to add a feature in tracing that Android had its
  own patch internally for. I took it back in 4.13. Now he realizes that
  he had a mistake, and swapped the values from what Android had. This
  means that the old Android tools will break when using a new kernel
  that has the new feature on it.

  The options are:

   1. To swap it back to what Android wants.
   2. Add a command line option or something to do the swap
   3. Just let Android carry a patch that swaps it back

  Since it requires setting a tracing option to enable this anyway, I
  doubt there are other users of this than Android. Thus, I've decided
  to take option 1. If someone else is actually depending on the order
  that is in the kernel, then we will have to revert this change and go
  to option 2 or 3"

From kernel v4.13 onwards, during which TGID was introduced, tracing
with systrace on all Android kernels will break (most Android kernels
have been on 4.9 with Android patches, so this issues hasn't been seen
yet). From v4.13 onwards things will break.

The chrome browser's tracing tools also embed the systrace viewer which
uses the legacy TGID format and updates to that are known to be
difficult to make.

Considering this, I suggest we make this change to the upstream kernel
and backport it to all Android kernels. I believe this feature is merged
recently enough into the upstream kernel that it shouldn't be a problem.
Also logically, IMO it makes more sense to group the TGID with the
TASK-PID and the CPU after these.

In 2016 GNU Make made a backwards incompatible change to the way '#'
characters were handled in Makefiles when used inside functions or
macros:

http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57

Due to this change, when attempting to run `make prepare' I get a
spurious make syntax error:

    /home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator.  Stop.

When inspecting `.fixdep.o.cmd' it includes two lines which use
unescaped comment characters at the top:

    \# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep)
    \# using basic dep data

This is because `tools/build/Build.include' prints these '\#'
characters:

    printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \
    printf '\# using basic dep data\n\n' >> $(dot-target).cmd;           \

This completes commit 9564a8cf ("Kbuild: fix # escaping in .cmd files

Dynamic ftrace requires modifying the code segments that are usually
set to read-only. To do this, a per arch function is called both before
and after the ftrace modifications are performed. The "before" function
will set kernel code text to read-write to allow for ftrace to make the
modifications, and the "after" function will set the kernel code text
back to "read-only" to keep the kernel code text protected.

The issue happens when dynamic ftrace is tested at boot up. The test is
done before the kernel code text has been set to read-only. But the
"before" and "after" calls are still performed. The "after" call will
change the kernel code text to read-only prematurely, and other boot
code that expects this code to be read-write will fail.

The solution is to add a variable that is set when the kernel code text
is expected to be converted to read-only, and make the ftrace "before"
and "after" calls do nothing if that variable is not yet set. This is
similar to the x86 solution from commit 16239630 ("ftrace, x86:
make kernel text writable only for conversions").

  mmc: renesas_sdhi_internal_dmac: Cannot clear the RX_IN_USE in abort
  mmc: renesas_sdhi_internal_dmac: Fix missing unmap in error patch

Pull ACPI fix from Rafael Wysocki:
 "Address a regression in ACPICA that ceased to clear the status of GPEs
  and fixed events before entering the ACPI S5 (off) system state during
  the 4.17 cycle which caused some systems to power up immediately after
  they had been turned off"

* tag 'acpi-4.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPICA: Clear status of all events when entering S5

It does not matter if the caller of may_use_simd() migrates to
another cpu after the call, but it is still important that the
kernel_neon_busy percpu instance that is read matches the cpu the
task is running on at the time of the read.

This means that raw_cpu_read() is not sufficient.  kernel_neon_busy
may appear true if the caller migrates during the execution of
raw_cpu_read() and the next task to be scheduled in on the initial
cpu calls kernel_neon_begin().

This patch replaces raw_cpu_read() with this_cpu_read() to protect
against this race.

Builds started failing in Fedora on Python 3.7 with:

    `.gnu.debuglto_.debug_macro' referenced in section
    `.gnu.debuglto_.debug_macro' of
    util/scripting-engines/trace-event-python.o: defined in discarded
    section

In Fedora, Python 3.7 added -flto to the list of --cflags and since it
was only applied to util/scripting-engines/trace-event-python.c and
scripts/python/Perf-Trace-Util/Context.c, linking failed.

It's not the first time the addition of flags has broken builds: commit
c6707fde ("perf tools: Fix up build in hardnened environments")
appears to have fixed a similar problem. "python-config --includes"
provides the proper -I flags and doesn't introduce additional CFLAGS.

The dictionaries are attached to the parameter tuple that steals the
references and takes care of releasing them when appropriate.  The code
should not decrement the reference counts explicitly.  E.g. if libpython
has been built with reference debugging enabled, the superfluous DECREFs
will trigger this error when running perf script:

  Fatal Python error: Objects/tupleobject.c:238 object at
  0x7f10f2041b40 has negative ref count -1
  Aborted (core dumped)

If the reference debugging is not enabled, the superfluous DECREFs might
cause the dict objects to be silently released while they are still in
use. This may trigger various other assertions or just cause perf
crashes and/or weird and unexpected data changes in the stored Python
objects.

Currently we display extra header line, like:

Fixing the condition and getting proper:

We are getting following warnings on gcc8 that break compilation:

  $ make
    CC       jvmti/jvmti_agent.o
  jvmti/jvmti_agent.c: In function ‘jvmti_open’:
  jvmti/jvmti_agent.c:252:35: error: ‘/jit-’ directive output may be truncated \
    writing 5 bytes into a region of size between 1 and 4096 [-Werror=format-truncation=]
    snprintf(dump_path, PATH_MAX, "%s/jit-%i.dump", jit_path, getpid());

There's no point in checking the result of snprintf call in
jvmti_open, the following open call will fail in case the
name is mangled or too long.

Using tools/lib/ function scnprintf that touches the return value from
the snprintf() calls and thus get rid of those warnings.

  $ make DEBUG=1
    CC       arch/x86/util/perf_regs.o
  arch/x86/util/perf_regs.c: In function ‘arch_sdt_arg_parse_op’:
  arch/x86/util/perf_regs.c:229:4: error: ‘strncpy’ output truncated before terminating nul
  copying 2 bytes from a string of the same length [-Werror=stringop-truncation]
    strncpy(prefix, "+0", 2);
    ^~~~~~~~~~~~~~~~~~~~~~~~

Using scnprintf instead of the strncpy (which we know is safe in here)
to get rid of that warning.
