powerpc: uaccess s/might_sleep/might_fault/
The only reason uaccess routines might sleep
is if they fault. Make this explicit.
Arnd Bergmann suggested that the following code
if (!is_kernel_addr((unsigned long)__pu_addr))
might_fault();
can be further simplified by adding a version of might_fault
that includes the kernel addr check.
Will be considered as a further optimization in future.
