MIPS: cache: Provide cache flush operations for XFS

2011-10-20T14:00:18Z

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 pages

2009-11-26T08:16:19Z

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. Signed-off-by: Ilya Loginov Cc: Ingo Molnar Cc: David Woodhouse Cc: Peter Horton Cc: "Ed L.
