4.19-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit ece9804985b57e1ccd83b1fb6288520955a29d51 ]
At some point we decided not to directly include kernel sources files
when building tools/perf/, but when tools/lib/subcmd/ was forked from
tools/perf it somehow ended up adding it via these two lines in its
Makefile:
CFLAGS += -I$(srctree)/include/uapi
CFLAGS += -I$(srctree)/include
As $(srctree) points to the kernel sources.
Removing those lines and keeping just:
CFLAGS += -I$(srctree)/tools/include/
Is enough to build tools/perf and tools/objtool.
This fixes the build when building from the sources in environments such
as the Android NDK crossbuilding from a fedora:26 system:
subcmd-util.h:11:15: error: expected ',' or ';' before 'void'
static inline void report(const char *prefix, const char *err, va_list params)
^
In file included from /git/perf/include/uapi/linux/stddef.h:2:0,
from /git/perf/include/uapi/linux/posix_types.h:5,
from /opt/android-ndk-r12b/platforms/android-24/arch-arm/usr/include/sys/types.h:36,
from /opt/android-ndk-r12b/platforms/android-24/arch-arm/usr/include/unistd.h:33,
from run-command.c:2:
subcmd-util.h:18:17: error: '__no_instrument_function__' attribute applies only to functions
The /opt/android-ndk-r12b/platforms/android-24/arch-arm/usr/include/sys/types.h
file that includes linux/posix_types.h ends up getting the one in the kernel
sources causing the breakage. Fix it.
Test built tools/objtool/ too.
