AMD IBS can do per-process profiling[1] and is no longer restricted to
per-cpu or systemwide only. Remove stale error message. Also, checking
just exclude_kernel is not sufficient since IBS does not support any
privilege filters. So include all exclude_* checks. And finally, move
these checks under tools/perf/arch/x86/ from generic code.
Before:
$ sudo ./perf record -e ibs_op//k -C 0
Error:
AMD IBS may only be available in system-wide/per-cpu mode. Try
using -a, or -C and workload affinity
After:
$ sudo ./perf record -e ibs_op//k -C 0
Error:
AMD IBS doesn't support privilege filtering. Try again without
the privilege modifiers (like 'k') at the end.
