Subject: [PATCH] Fix flush_dcache_page() for usage in irq context
flush_dcache_page() can be called with IRQs disabled, e.g. from
aio_complete().
Fix flush_dcache_page() on the arm, parisc and nios2 architectures
to not unintentionally re-enable IRQs by using xa_lock_irqsave() instead
of xa_lock_irq() for the flush_dcache_mmap_*lock() functions.
Please consider adding a Fixes: tag such that this patch is picked up

Sure. I'll probably split it up as per-arch patch as well. Just wanted
to get some feedback first.
