I had a look throughout, and couldn't see anything untoward other than
the couple of nits that were already pointed out. Killing the horrible
asm macros definitely brings a bit of fresh air to this code base.
Given the sensitivity of the change, I'd like this to simmer in -next
for a bit. How do you want this to be merged? I'm happy to take the
whole thing in kvmarm, and share the branch with arm64.
I assume you'll post a v2 anyway?
Thanks,
M.
