Subject: [PATCH] [MIPS] Enable the timerfd_*() o32 system calls

This patch enables the system calls timerfd_create(), timerfd_settime()
and timerfd_gettime() for MIPS architecture.

Please see the following Bugzilla entry for more details:

http://bugzilla.kernel.org/show_bug.cgi?id=10038

This was tested using a Malta 4Kc board in both little-endian and
big-endian modes. The unit test program is available from the URL
above.

Note that only the "o32"-style system calls have been added. This is
due to the fact that I have no suitable equipment to test the other
flavors of MIPS ABI.

Thanks. I added the missing bits for the others ABIs and applied the
combined patch.
