[PATCH v3 0/6] Add support for pldw instruction on v7 MP cores

[Will Deacon]

Hello,

This is version three of the patches I have previously posted here:

v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-July/185663.html
v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-July/186411.html

This version is simply a rebase on top of v3.12-rc1, since I concentrated
on getting my memory barrier improvements into 3.12 ahead of this series.
I'm aiming to get this merged for 3.13.

All feedback welcome,

Will
