It is possible for firmware to allocate memory ranges outside
the range of physical memory that we support (MAX_PHYSMEM_BITS).
This patch adds a bounds check to ensure that any hotplugged

This is a follow up series to the ensure perf treats perf_event_paranoid and
kptr_restrict in a way that is similar to the kernel's. That includes use of
capabilities instead of euid==0, when possible, as well as adjusting the logic
and fixing bugs.
Prior discussion:
Check for ref_reloc_sym before using it instead of checking
symbol_conf.kptr_restrict and relying solely on that check.

Perf was too restrictive about sysctl kernel.perf_event_paranoid. The
kernel only disallows profiling when perf_event_paranoid > 1. Make perf do
the same.

The kernel is using CAP_SYS_ADMIN instead of euid==0 to override
perf_event_paranoid check. Make perf do the same.

The kernel is using CAP_SYSLOG capability instead of uid==0 and euid==0
when checking kptr_restrict. Make perf do the same.
Also, the kernel is a more restrictive than "no restrictions" in case of
kptr_restrict==0, so add the same logic to perf.

No sense in doing that lookup before figuring out if it will be used,
i.e. if the pid is being filtered that tmp space lookup will be useless.
