Yeah, sorry, I wasn't clear. If you look back at what I sent in
https://www.mail-archive.com/devicetree at vger.kernel.org/msg30473.html
([PATCHv5 0/3] ARM: implement workaround for Cortex-A9/PL310/PCIe
deadlock), there were three patches:

 PATCH 1/3, "ARM: mm: add support for HW coherent systems in PL310
 cache", for Russell. It has already been merged by Russell in
 "git-curr", as visible at
 http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=8076/1.
 I'm hoping this is scheduled for 3.16, because I need this patch for
 3.16 to avoid the PCIe deadlock.

 PATCH 2/3 and 3/3 are related, and the latter is needed to solve the
 PCIe deadlock, by using the new DT property made available in PATCH
 1/3. PATCH 2/3 is ARM: mvebu: move Armada 375 external abort logic as
 a quirk and PATCH 3/3 is ARM: mvebu: update L2/PCIe deadlock
 workaround after L2CC cleanup.

All in all, I'm hoping for the series at
https://www.mail-archive.com/devicetree at vger.kernel.org/msg30473.html
to fully show up in 3.16, because it's really related to fixing a
serious PCIe deadlock (can be triggered in under a minute of PCIe
usage).
Now that Russell is pushing PATCH 1/3 in the 3.16-rc cycle, can you
push PATCH 2/3 and PATCH 3/3 pointed above into the 3.16-rc cycle as
well?
2 and 3 are now in mvebu/fixes.

thx,

Jason.
