The patch titled
     slob: fix page order calculation on not 4KB page
has been removed from the -mm tree.  Its filename was
     slob-fix-page-order-calculation-on-not-4kb-page.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: slob: fix page order calculation on not 4KB page
From: Akinobu Mita <akinobu.mita@gmail.com>

SLOB doesn't calculate correct page order when page size is not 4KB.  This
patch fixes it with using get_order() instead of find_order() which is SLOB
version of get_order().
