Subject: linux-next: manual merge of the signal tree with the mips tree

Hi Al,

Today's linux-next merge of the signal tree got a conflict in
arch/mips/kernel/syscall.c between commit 7034228792cc ("MIPS: Whitespace
cleanup") from the mips tree and commit 50150d2bb903 ("mips: switch to
generic sys_fork() and sys_clone()") from the signal tree.

I fixed it up (the sys_clone stuff was removed by the latter - see below)
and can carry the fix as necessary (no action is required).

Cheers,
