Whoa, that's a syscall I never expected to see. What's it do?
Replaces the TESTSET instruction, which has a few errata that make it
unreliable. It's used by the pthreads library to provide atomic operations.
Shouldn't
it be using get_user() and put_user()? Or will this forever be a nommu
arch?
We currently don't expect that this code will ever support a MMU, but I
suppose it could use get/put_user for clarity.
