2009-09-01Revert "sh: Kill off now redundant local irq disabling."Paul Mundt
This reverts commit 64a6d72213dd810dd55bd0a503c36150af41c3c3. Unfortunately we can't use on_each_cpu() for all of the cache ops, as some of them only require preempt disabling. This seems to be the same issue that impacts the mips r4k caches, where this code was based on. This fixes up a deadlock that showed up in some IRQ context cases.

2009-08-21sh: Kill off now redundant local irq disabling.Paul Mundt
on_each_cpu() takes care of IRQ and preempt handling, the localized handling in each of the called functions can be killed off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-08-21sh: Make cache flushers SMP-aware.Paul Mundt
This does a bit of rework for making the cache flushers SMP-aware. The function pointer-based flushers are renamed to local variants with the exported interface being commonly implemented and wrapping as necessary. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
