Pull perf fixes from Thomas Gleixner:
"A couple of fixes for perf and kprobes:
- Add he missing exclude_kernel attribute for the precise_ip level so
!CAP_SYS_ADMIN users get the proper results.
- Warn instead of failing completely when perf has no unwind support
for a particular architectiure built in.
- Ensure that jprobes are at function entry and not at some random
place"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
kprobes: Ensure that jprobe probepoints are at function entry
kprobes: Simplify register_jprobes()
kprobes: Rename [arch_]function_offset_within_entry() to [arch_]kprobe_on_func_entry()
perf unwind: Do not fail due to missing unwind support
perf evsel: Set attr.exclude_kernel when probing max attr.precise_ip
