John David Anglin 6d2439d955 parisc: fixes and cleanups in page cache flushing (3/4) 
flush_cache_mm, for the non current case also uses flush_dcache_page_asm
and flush_icache_page_asm which are TMPALIAS flushes.

For the non current case, the algorithm used by get_ptep is derived from the
vmalloc_to_page implementation in vmalloc.c.  It is essentially a generic page
table lookup.  The other alternative was to duplicate the lookup in entry.S.
The break point for switching to a full cache flush is somewhat arbitrary.  The
same approach is used in flush_cache_range for non current case.  In a GCC
build and check, many small programs are executed and this change provided a
significant performance enhancement, e.g. GCC build time was cut almost in half
on a rp3440 at j4.  Previously, we always flushed the entire cache.
