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.
