Subject: [PATCH 3.12 29/63] ARM: KVM: disable KVM in Kconfig on big-endian systems

From: Will Deacon <will.deacon@....com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 4e4468fac4381b92eb333d94256e7fb8350f3de3 upstream.

KVM currently crashes and burns on big-endian hosts, so don't allow it
to be selected until we've got that fixed.
