powerpc/64s: masked_interrupt() returns to kernel so avoid restoring r13 Places in the kernel where r13 is not the PACA pointer must have maskable interrupts disabled, so r13 does not have to be restored when returning from a soft-masked interrupt. We should never have interrupts soft disabled when we're in user space. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
