perf_counter: Add mmap event hooks to mprotect()
Some JIT compilers allocate memory for generated code with posix_memalign() + mprotect() so we need to hook into mprotect() to make sure 'perf' is aware that we're executing code in anonymous memory. [ penberg@cs.helsinki.fi: move the hook to sys_mprotect() ] Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi> LKML-Reference: <Pine.LNX.4.64.0906082111030.12407@melkki.cs.Helsinki.FI> Signed-off-by: Ingo Molnar <mingo@elte.hu>
