Helge Deller e82a3b7512 parisc: ensure broadcast tlb purge runs single threaded ... The TLB flushing functions on hppa, which causes PxTLB broadcasts on the system bus, needs to be protected by irq-safe spinlocks to avoid irq handlers to deadlock the kernel. The deadlocks only happened during I/O intensive loads and triggered pretty seldom, which is why this bug went so long unnoticed. Signed-off-by: Helge Deller <deller@gmx.de> [edited to use spin_lock_irqsave on UP as well since we'd been locking there all this time anyway, --kyle] Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>		2009-07-03 03:34:09 +00:00
