Matthew Wilcox 65ee8f0a7f [PARISC] Enable interrupts while spinning 
Use the __raw_spin_lock_flags routine so we can take an interrupt while
spinning.  This re-fixes a bug jejb found on 2005-10-20:

CPU0 does a flush_tlb_all holding the vmlist_lock for write.
CPU1 tries a cat of /proc/meminfo which tries to acquire vmlist_lock for read
CPU1 is now spinning with interrupts disabled
CPU0 tries to execute a smp_call_function to flush the local tlb caches
This is now a deadlock because CPU1 is spinning with interrupts disabled and
can never receive the IPI
