From: Chen, Kenneth W Date: Wed, 22 Mar 2006 18:49:00 +0000 (-0800) Subject: [IA64] fix ia64 is_hugepage_only_range X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2332c9ae7911618575241e0c843cd686968db8e3;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [IA64] fix ia64 is_hugepage_only_range fix is_hugepage_only_range() definition to be "overlaps" instead of "within architectural restricted hugetlb address range". Simplify the ia64 specific code that used to use is_hugepage_only_range() to just check which region the address is in.
