    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.

commit 874f257d4af720867cba996dafeead114e37ebbe

    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.
