perf powerpc: Fix build-test failure
'make -C tools/perf build-test' is failing with below log for poewrpc.
In file included from /tmp/tmp.3eEwmGlYaF/perf-4.8.0-rc4/tools/perf/perf.h:15:0,
from util/cpumap.h:8,
from util/env.c:1:
/tmp/tmp.3eEwmGlYaF/perf-4.8.0-rc4/tools/perf/perf-sys.h:23:56:
fatal error: ../../arch/powerpc/include/uapi/asm/unistd.h: No such file or directory
compilation terminated.
I bisected it and found it's failing from commit ad430729ae00 ("Remove:
kernel unistd*h files from perf's MANIFEST, not used").
Header file '../../arch/powerpc/include/uapi/asm/unistd.h' is included
only for powerpc in tools/perf/perf-sys.h.
By looking closly at commit history, I found little weird thing:
Commit f2d9cae9ea9e ("perf powerpc: Use uapi/unistd.h to fix build
error") replaced 'asm/unistd.h' with 'uapi/asm/unistd.h'
Commit d2709c7ce4c5 ("perf: Make perf build for x86 with UAPI
disintegration applied") removes all arch specific 'uapi/asm/unistd.h'
for all archs and adds generic <asm/unistd.h>.
Commit f0b9abfb0446 ("Merge branch 'linus' into perf/core") again
includes 'uapi/asm/unistd.h' for powerpc. Don't know how exactly this
happened as this change is not part of commit also.
