Subject: Merge branch 'stericsson/cleanup' into next/timer
X-Git-Tag: v3.2-rc1~96^2
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=eed1e576507b52e03e549e0c9e0c747978122403;p=linux.git

Merge branch 'stericsson/cleanup' into next/timer

The timer and cleanup branches from stericsson conflict,
so I'm merging them here.
