Subject[PATCH 3.16.y-ckt 123/168] powerpc/powernv: Honor the generic "no_64bit_msi" flag
Date
3.16.7-ckt3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

commit 360743814c4082515581aa23ab1d8e699e1fbe88 upstream.

Instead of the arch specific quirk which we are deprecating
and that drivers don't understand.

[ luis: backported to 3.16: adjusted context ]
