[PATCH] x86: fix oprofile kernel callgraph regression
Fix x86 oprofile regression introduced by:
commit c34d1b4d165c67b966bca4aba026443d7ff161eb
[PATCH] mm: kill check_user_page_readable
That commit reorganized tests for the userspace stack walking moving all
those tests into dump_backtrace(), however, dump_backtrace() was used for
both userspace and kernel stalk walking. The result is typically no
recorded callgraph information for kernel samples.
Revive the original function as dump_kernel_backtrace() and rename the
other to dump_user_backtrace() to avoid future confusion.
