sh: Fix occasional FPU register corruption under preempt.

2008-03-26T10:02:47Z

Presently with preempt enabled there's the possibility to be preempted after the TIF_USEDFPU test and the register save, leading to bogus state post-__switch_to(). Use an explicit preempt_disable()/enable() pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86 change. Reported-by: Takuo Koguchi Signed-off-by: Paul Mundt
