re: __atomic_test_and_set() and mips o32 - help wanted

[matthew green <mrg%eterna23.net@localhost>]

FWIW, one problem with the RAS solution is that we disable RAS
on SMP mips kernels, and i'm not sure how it would be fixed..

someone else could totally implement a better solution -- my
goal is to keep mips working with newer GCC, and for something
that is only rarely used (so far, only GDB has triggered this,
though anything using modern C++ test_and_set() would also
trigger the same issue -- this is how GDB does), i'm not going
to worry about better myself.
