I should have used git format-patch. Here it is again (if it still doesn't work, I'll mail it to you separately).

From 631d16e6284ddecd9d261f929582244f6757b678 Mon Sep 17 00:00:00 2001 From: Catalin Marinas <catalin.marinas@arm.com> Date: Wed, 9 May 2012 16:45:46 +0100 Subject: [PATCH] kmemleak: Fix the kmemleak tracking of the percpu areas with !SMP
Kmemleak tracks the percpu allocations via a specific API and the originally allocated areas must be removed from kmemleak (via kmemleak_free). The code was already doing this for SMP systems.
