On PPC32, enums are 32 bits, so __PERF_SAMPLE_CALLCHAIN_EARLY is
out of scope. The following sparse warning is encountered:
CHECK arch/powerpc/kernel/process.c
./include/uapi/linux/perf_event.h:147:56: warning: cast truncates bits from
constant value (8000000000000000 becomes 0)
This patch changes it to a #define
Fixes: 6cbc304f2f360 ("perf/x86/intel: Fix unwind errors from PEBS entries
(mk-II)")
