Subject: [stable 3.10.y] Please backport a56a5cf1f2ec "ARM: highbank: avoid
 L2 cache smc calls when PL310 is not present"

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.
