-stable review patch. If anyone has any objections, please let us know. --------------------- From: James Bottomley The spinlock is held over too large a region: pscratch is a permanent address (it's allocated at boot time and never changes). All you need the smp lock for is mediating the scratch in use flag, so fix this by moving the spinlock into the case where we set the pscratch_busy flag to false.
