Hi Linus,

Please pull this pair of arm64 fixes for -rc6. There's a fix for missing
locking around kernel page-table allocation causing a crash with
virtio-mem and a fix for a smatch warning in the kexec code where we
would return 0 on the error path.

With any luck, that's us done for the year.

Cheers,

Will

I you haven't pulled this yet, please discard the request. I'll revert
the above commit as it causes a regression, reported here:

https://lore.kernel.org/all/Ybn4EfweLqKtyW0+@fixkernel.com/

Will is already on holiday, so I'll retag the branch tomorrow and send a
new pull request.

Thanks and sorry for the trouble.
