[GIT PULL] arm64: fixes for -rc7

[Will Deacon]

Hi Linus,

Inevitably, after saying that I hoped we would be done on the fixes front,
a couple of issues have cropped up over the last week. Next time I'll stay
schtum.

As usual, details are in the tag, but we've fixed an over-eager BUILD_BUG_ON()
which Arnd ran into with arndconfig, as well as ensuring that KPTI really
is disabled on Thunder-X1, where the cure is worse than the disease (this
regressed when we reworked the heterogeneous CPU feature checking).

Please pull.

Thanks,

Will
