The patch titled
Optimize free_one_page
has been removed from the -mm tree. Its filename is
optimize-free_one_page.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Optimize free_one_page
From: Christoph Lameter <clameter@xxxxxxx>
Free one_page currently adds the page to a fake list and calls
free_page_bulk. Fee_page_bulk takes it off again and then calles
__free_one_page.
Make free_one_page go directly to __free_one_page. Saves list on / off and
a temporary list in free_one_page for higher ordered pages.
