2008-11-27	[ARM] clearpage: provide our own clear_user_highpage()	Russell King	1	-10/+10
	For similar reasons as copy_user_page(), we want to avoid the additional kmap_atomic if it's unnecessary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-27	[ARM] copypage: provide our own copy_user_highpage()	Russell King	1	-6/+17
	We used to override the copy_user_page() function. However, this is not only inefficient, it also causes additional complexity for highmem support, since we convert from a struct page to a kernel direct mapped address and back to a struct page again. Moreover, with highmem support, we end up pointlessly setting up kmap entries for pages which we're going to remap. So, push the kmapping down into the copypage implementation files where it's required. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
