[PATCH] sh: PREEMPT_ACTIVE fix
Port Paulus's ppc64 fix to sh:
When the generic IRQ stuff went in, it seems that HARDIRQ_BITS got bumped
from 9 (for ppc64) up to 12. Consequently, the PREEMPT_ACTIVE bit is now
within HARDIRQ_MASK, and I get in_interrupt() falsely returning true when
PREEMPT_ACTIVE is set, and thus a BUG_ON tripping in arch/ppc64/mm/tlb.c.
