Subject: [PATCH 0/2 V2] Add trace points to [m|mun|mre]map and brk

This patch set is a resubmit of several patches I sent out earlier that adds
trace points to the mmap family.  These events report addresses and sizes when
each function returns success.  They will be used by a userspace tool that will model memory usage.

Changes from V1:
- Group mmap, munmap, and brk into first patch (all in mmap.c) and mremap into
  second (in mremap.c)
- Use DEFINE_EVENT_CLASS and DEFINE_EVENT for mmap and brk events

Eric B Munson (2):
  Add trace points to mmap, munmap, and brk
  Add mremap trace point
