ARM: 7765/1: perf: Record the user-mode PC in the call chain.
commit c5f927a6f62196226915f12194c9d0df4e2210d7 upstream.
With this change, we no longer lose the innermost entry in the user-mode
part of the call chain. See also the x86 port, which includes the ip.
It's possible to partially work around this problem by post-processing
the data to use the PERF_SAMPLE_IP value, but this works only if the CPU
wasn't in the kernel when the sample was taken.
