[RFC] Add support for tracing memory related syscalls

[Namhyung Kim]

Hi,

When I was debugging a memory related problem, I really want to see
only those syscalls but it wans't suppport by strace.  Hence I decided
to create a patch.  I guess others may want this too.

This patch was made mostly by following script:

  $ cat convert-tm.cmd
  s/TD,\t(sys_old_mmap)/TD|TM,\t\1/
  s/TD,\t(sys_mmap)/TD|TM,\t\1/
  s/0,\t(sys_mprotect)/TM,\t\1/
  s/0,\t(sys_munmap)/TM,\t\1/
  s/0,\t(sys_brk)/TM,\t\1/
  s/0,\t(sys_mremap)/TM,\t\1/
  s/0,\t(sys_msync)/TM,\t\1/
  s/0,\t(sys_mincore)/TM,\t\1/
  s/0,\t(sys_madvise)/TM,\t\1/
  s/0,\t(sys_mlock)/TM,\t\1/
  s/0,\t(sys_munlock)/TM,\t\1/
  s/0,\t(sys_mlockall)/TM,\t\1/
  s/0,\t(sys_munlockall)/TM,\t\1/
  s/0,\t(sys_remap_file_pages)/TM,\t\1/
  s/0,\t(sys_mbind)/TM,\t\1/
  s/0,\t(sys_set_mempolicy)/TM,\t\1/
  s/0,\t(sys_get_mempolicy)/TM,\t\1/
  s/0,\t(sys_migrate_pages)/TM,\t\1/
  s/TD\t(sys_vmsplice)/TD|TM,\t\1/
  s/0,\t(sys_move_pages)/TM,\t\1/
  
  $ for F in $(find linux/ -name syscallent.h); do sed -r -f convert-tm.cmd -i $F; done

Tested on my Fedora 17 x86_64 box.

Thanks,
Namhyung
