*	MIPS: cache: Provide cache flush operations for XFS	Ralf Baechle	2011-10-20	1	-0/+24
\| \| \| \| \| \| \| \| \| \| \| \|	Until now flush_kernel_vmap_range() and invalidate_kernel_vmap_range() did not exist on MIPS resulting in heavy cache corruption on XFS filesystems. Left for the post-3.0 time: optimization and make this work with highmem, too. Since the combination of highmem + cache aliases atm doesn't work this isn't a regression.

*	block: add helpers to run flush_dcache_page() against a bio and a request's ↵	Ilya Loginov	2009-11-26	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.
