Hi stable@,
Please could you backport the changeset in $SUBJECT (and below) to
3.10.y. It went into v3.12-rc1 so I suppose you might also consider it
for other stable branches before then which are still live.
I thought it might require 0b53c11d533a "ARM: move outer_cache
declaration out of ifdef" but Kconfig seems to be such that it isn't
needed in practice.
Cheers,
Ian.

ARM: highbank: avoid L2 cache smc calls when PL310 is not present
While Midway firmware handles L2 smc calls as nops, the custom smc calls
present a problem when running virtualized Midway guest. They aren't
needed so just avoid calling them.
In the process, cleanup the L2X0 ifdefs and use IS_ENABLED instead.

Thank you Ian, I'll queue this commit for the 3.11 kernel as well.

This doesn't apply to the 3.10 stable tree, so if you want it there, can
you provide a backported version?
thanks,

Strange, they both cherry-picked cleanly onto v3.10.33 for me. I've
pushed the resulting tree.

Can you just email these to me, I can't easily take git pulls for stable
patches, sorry.
