<div class='commit-subject'>perf/core: Fix PERF_RECORD_MMAP2 prot/flags for anonymous memory</div><div class='commit-msg'>Andres reported that MMAP2 records for anonymous memory always have
their protection field 0.

Turns out, someone daft put the prot/flags generation code in the file
branch, leaving them unset for anonymous memory.
