ARM: 6343/1: wire up fanotify and prlimit64 syscalls on ARM

Browse Source 
The 2.6.36-rc kernel added three new system calls:
fanotify_init, fanotify_mark, and prlimit64.  This patch
wires them up on ARM.

The only non-trivial issue here is the u64 argument to
sys_fanotify_mark(), but it is the 3rd argument and thus
passed in r2/r3 in both kernel and user space, so it causes
no problems.

Tested with a 2.6.36-rc2 EABI kernel on an ixp4xx machine.
