Helge Deller d755bd2cae parisc: Ensure page alignment in flush functions
Matthew Wilcox noticed, that if ARCH_HAS_FLUSH_ON_KUNMAP is defined
(which is the case for PA-RISC), __kunmap_local() calls
kunmap_flush_on_unmap(), which may call the parisc flush functions with
a non-page-aligned address and thus the page might not be fully flushed.

This patch ensures that flush_kernel_dcache_page_asm() and
flush_kernel_dcache_page_asm() will always operate on page-aligned
addresses.
