[PATCH 0/3] arm64: Kill ESR_LNX_EXEC

[mark.rutland@arm.com (Mark Rutland)]

Currently we (ab)use a reserved bit in ESR_ELx for our own purposes as
ESR_LNX_EXEC, which isn't ideal, especially as we're inconsistent with our
mnemonic usage. This series removes ESR_LNX_EXEC entirely, avoiding (ab)use of
reserved ESR_ELx bits, and makes things a little more consistent.

I've extracted this from my entry-deasm branch [1], and rebased to v4.7-rc1.
I've split the KVM changes as the KVM code is undergoing rapid change these
days, and it should be possible to take those as a subsequent cleanup rather
than forcing a painful merging process.

Thanks,
Mark.
