The patch titled
xip: fix get_zeroed_page with __GFP_HIGHMEM
has been removed from the -mm tree. Its filename was
xip-fix-get_zeroed_page-with-__gfp_highmem.patch

------------------------------------------------------
Subject: xip: fix get_zeroed_page with __GFP_HIGHMEM
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
The use of get_zeroed_page() with __GFP_HIGHMEM is invalid. Use
alloc_page() with __GFP_ZERO instead of invalid get_zeroed_page().
(This patch is only compile tested)
