linux.git/tools/include/linux, branch v4.13

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2017-07-03T19:40:46+00:00

Pull perf updates from Ingo Molnar:
 "Most of the changes are for tooling, the main changes in this cycle were:

   - Improve Intel-PT hardware tracing support, both on the kernel and
     on the tooling side: PTWRITE instruction support, power events for
     C-state tracing, etc. (Adrian Hunter)

   - Add support to measure SMI cost to the x86 architecture, with
     tooling support in 'perf stat' (Kan Liang)

   - Support function filtering in 'perf ftrace', plus related
     improvements (Namhyung Kim)

   - Allow adding and removing fields to the default 'perf script'
     columns, using + or - as field prefixes to do so (Andi Kleen)

   - Allow resolving the DSO name with 'perf script -F brstack{sym,off},dso'
     (Mark Santaniello)

   - Add perf tooling unwind support for PowerPC (Paolo Bonzini)

   - ... and various other improvements as well"

tools: Adopt __aligned from kernel sources

2017-06-19T18:27:08+00:00

To have a more compact way to ask the compiler to use a specific
alignment, making tools/ look more like kernel source code.

tools: Adopt __packed from kernel sources

2017-06-19T18:27:07+00:00

To have a more compact way to ask the compiler to not insert alignment
paddings in a struct, making tools/ look more like kernel source code.

tools: Adopt __noreturn from kernel sources

2017-06-19T18:14:58+00:00

To have a more compact way to specify that a function doesn't return,
instead of the open coded:

	__attribute__((noreturn))

And use it instead of the tools/perf/ specific variation, NORETURN.
