[PATCH] uml: arch_prctl should set thread fs
In my previous x86_64 thread fix, I forgot to initialize thread.arch.fs in
arch_prctl. A process calling arch_prctl to set %fs would lose it on the
next context switch.
It also turns out that you can switch to a process which is in the process
of exiting and which has lost its mm. In this case, it's worse than
useless to try to call arch_prctl on the host process.
