Paul Burton bd239f1e14 MIPS: Disable preemption during prctl(PR_SET_FP_MODE, ...) 
Whilst a PR_SET_FP_MODE prctl is performed there are decisions made
based upon whether the task is executing on the current CPU. This may
change if we're preempted, so disable preemption to avoid such changes
for the lifetime of the mode switch.
