The patch titled
page flags: handle PG_uncached like all other flags
has been removed from the -mm tree. Its filename was
page-flags-handle-pg_uncached-like-all-other-flags.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: page flags: handle PG_uncached like all other flags
From: Christoph Lameter <clameter@xxxxxxx>
Remove the special setup for PG_uncached and simply make it part of the enum.
The page flag will only be allocated when the kernel build includes the
uncached allocator.
