parisc: Convert to read/update_persistent_clock

This patch converts the parisc architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future.

I have not built or tested this patch, so help from arch maintainers would be appreciated.

xfs: fix xfs to work with Virtually Indexed architectures

xfs_buf.c includes what is essentially a hand rolled version of blk_rq_map_kern(). In order to work properly with the vmalloc buffers that xfs uses, this hand rolled routine must also implement the flushing API for vmap/vmalloc areas.

arm: add mm API for DMA to vmalloc/vmap areas

ARM cannot prevent cache movein, so this patch implements both the flush and invalidate pieces of the API.

parisc: add mm API for DMA to vmalloc/vmap areas

We already have an API to flush a kernel page along an alias address, so use it. The TLB purge prevents the CPU from doing speculative moveins on the flushed address, so we don't need to implement and invalidate.

mm: add coherence API for DMA to vmalloc/vmap areas

On Virtually Indexed architectures (which don't do automatic alias resolution in their caches), we have to flush via the correct virtual address to prepare pages for DMA. On some architectures (like arm) we cannot prevent the CPU from doing data movein along the alias (and thus giving stale read data), so we not only have to introduce a flush API to push dirty cache lines out, but also an invalidate API to kill inconsistent cache lines that may have moved in before DMA changed the data

parisc: drop unnecessary cast in __ldcw_align() macro

__ldcw_align() can directly access the slock member of struct arch_spinlock_t instead of using an ugly cast.
