Ingo Molnar eae7a755ee perf tools, x86: Build perf on older user-space as well ... On ancient systems I get this build failure: util/../../../arch/x86/include/asm/unistd.h:67:29: error: asm/unistd_64.h: No such file or directory In file included from util/cache.h:7, from builtin-test.c:8: util/../perf.h: In function ‘sys_perf_event_open’:In file included from util/../perf.h:16 perf.h:170: error: ‘__NR_perf_event_open’ undeclared (first use in this function) The reason is that this old system does not have the split unistd.h headers yet, from which to pick up the syscall definitions. Add the syscall numbers to the already existing i386 and x86_64 blocks in perf.h, and also provide empty include file stubs. With this patch perf builds and works fine on 5 years old user-space as well.
