Subject: Re: [GIT PULL] last minute percpu fix for v3.15-rc8

Hello, again.

My script applied the patch with the wrong author.  It should have
been Heiko instead of Sebastian.  I fixed up percpu/for-3.15-fixes
branch accordingly.  The updated pull-request output follows.  There
is no content change.

Thanks.

The following changes since commit 5a838c3b60e3a36ade764cf7751b8f17d7c9c2da:

  percpu: make pcpu_alloc_chunk() use pcpu_mem_free() instead of kfree() (2014-04-14 16:18:06 -0400)
