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 . 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.
