MIPS: hang in kmalloc with seccomp writer locks

Hi Kees,

My MIPS32 toys hang early during bootup at the first kmalloc() with
seccomp enabled.
I've bisected it to commit dbd952127d11bb44a4ea30b08cc60531b6a23d71
("seccomp: introduce writer locking"). And indeed, reverting this
commit fixes the hang.

I'm not sure if seccomp is even working on MIPS, but I've never had
problems with
it before so I thought I let you know.

Thanks, and have a nice day!
Manuel
