From: James Bottomley <James.Bottomley@xxxxxxxxxxxxxxxxxxxxx> This is essentially a small tidy up from the previous series. I thought about the Ben H additions, but since power doesn't seem to need this, they seemed a bit moot (we can expand the API when an actual user comes along). The patch series adds a flush/invalidate_kernel_vmap_range() API that drivers using vmap/vmalloc areas must use before sending tohse areas for I/O. This makes it crystal clear that coherence on these areas is the responsibility of the driver alone. Fortunately xfs is the only thing in the kernel actually doing I/O to vmap areas. Sin ce xfs is completely broken on most VIPT architectures without this, I'd like to submit it as a bug fix for 2.6.33. Unfortunately, we actually have some parisc xfs users whose data is curently at severe risk.
