parisc: fixes and cleanups in page cache flushing (4/4)
CONFIG_PARISC_TMPALIAS enables clear_user_highpage and copy_user_highpage.
These are essentially alternative implementations of clear_user_page and
copy_user_page. They don't have anything to do with x86 high pages, but they
build on the infrastructure to save a few instructions. Read the comment in
clear_user_highpage as it is very important to the implementation. For this
reason, there isn't any gain in using the TMPALIAS/highpage approach.
