Commit cf6ce084 (MIPS: Fix syscall_get_nr for the syscall exit
tracing.) broke 3.13 and 3.14 stable tree due to the missing syscall
argument. So, get the syscall from regs[2] before it's trashed.
This patch should go to the 3.13 and 3.14 stable tree.

Hi,
Commit cf6ce084 (MIPS: Fix syscall_get_nr for the syscall exit..) is not
in the stable branches. How did it brake the 3.13 and 3.14 build?
