: [PATCH] Collect both user and kernel events for
autofdo tests and autoprofiledbootstrap
I don't run this with elevated privileges but I set
/proc/sys/kernel/kptr_restrict to 0. Setting that does require elevated
privileges.
If that's not acceptable, the only fix I can think of is to
llect both user and kernel events for autofdo
tests and autoprofiledbootstrap

When we collect just user events for autofdo with lbr we get some events where
branch
sources are kernel addresses and branch targets are user addresses. Without
kernel MMAP
events create_gcov can't make sense of kernel addresses. Currently create_gcov
fails if
it can't map at least 95% of event
