tools: Copy coresight-pmu.h header file needed by perf tools

2016-08-23T18:37:33+00:00

Directly accessing kernel files is not allowed anymore.  As such making
file coresight-pmu.h accessible by the perf tools and complain if this
copy strays from the one found in the main kernel tree.

tools: Introduce tools/include/linux/time64.h for SEC_PER_SEC macros

2016-08-23T18:37:33+00:00

And remove it from tools/perf/{perf,util}.h, making code that needs
these macros to include linux/time64.h instead, to match how this is
used in the kernel sources.

tools lib: Reinstate strlcpy() header guard with UCLIBC

2016-08-18T19:19:13+00:00

perf tools build in recent kernels spews splat when cross compiling with uClibc:

|   CC       util/alias.o
| In file included from tools/perf/util/../ui/../util/cache.h:8:0,
|                 from tools/perf/util/../ui/helpline.h:7,
|                 from tools/perf/util/debug.h:8,
|                 from arch/../util/cpumap.h:9,
|                 from arch/../util/env.h:5,
|                 from arch/common.h:4,
|                 from arch/common.c:3:
| tools/include/linux/string.h:12:15: warning: redundant redeclaration of ‘strlcpy’ [-Wredundant-decls]
|  extern size_t strlcpy(char *dest, const char *src, size_t size);
               ^
This is after commit 61a6445e463a31 ("tools lib: Guard the strlcpy() header with
__GLIBC__").

The problem is uClibc also defines __GLIBC__ for exported headers for
applications. So add that specific check to not trip for uClibc.

We were also using this directly from the kernel sources, the two last
cases, fix it.

tools: Make "__always_inline" just "inline" on Android

2016-07-14T15:03:04+00:00

As the gcc there is producing tons of:

  "warning: always_inline function might not be inlinable"

At least on android-ndk-r12/platforms/android-24/arch-arm, so, for the
time being, use this big hammer.

tools: Work around BITS_PER_LONG related build failure in objtool

2016-07-13T07:37:43+00:00

The objtool build fails with the recent changes to the bits-per-long
headers:

  tools/include/linux/bitops.h:12:0: error: "BITS_PER_LONG" redefined [-Werror]

Which got introduced by:

  bb9707077b4e tools: Copy the bitsperlong.h files from the kernel

Work it around for the time being.

tools lib: Guard the strlcpy() header with GLIBC

2016-07-12T18:20:29+00:00

Better to whitelist it for libraries that require it (glibc) than
blacklist it with the ones that don't (uclibc, musl libc, etc).
