[GIT PULL] arm64: late fixes for 4.3

[Will Deacon]

Hi Linus,

Apologies for this being so late, but we've uncovered a few nasty issues
on arm64 which didn't settle down until yesterday and the fixes all look
suitable for 4.3. Of the four patches, three of them are Cc'd to stable,
with the remaining patch fixing an issue that only took effect during
the merge window. Brief summaries are available in the tag.

Please pull.

Thanks,

Will
