The patch titled
Subject: mm/highmem: simplify is_highmem()
has been removed from the -mm tree. Its filename was
mm-highmem-simplify-is_highmem.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Chanho Min <chanho.min@xxxxxxx>
Subject: mm/highmem: simplify is_highmem()
is_highmem() can be simplified by use of is_highmem_idx(). This patch
removes redundant code and will make it easier to maintain if the zone
policy is changed or a new zone is added.
