[PATCH v3 0/2] arm: enable MTE for QEMU + kvm

[Cornelia Huck]

After wayyy too long (last version was sent in *July*), a respin of my
kvm/mte series. Still no migration support. I've been hacking around on
a device for transferring tags while stopped, but don't really have anything
to show, probably because I get distra- <ohh, what's that?>

...I guess you get the point :(

Anyway, I wanted to post this as non-RFC; likely too late for 7.2, but maybe
for 8.0 (and I'd get a chance to make at least pre-copy migration work; I'm open
to suggestions for that. Support for post-copy needs kernel-side changes.) 
Tested
on the FVP models; qtests only on a non-MTE KVM host.

Changes v2->v3:
- rebase to current master
- drop some parts of the qtests that didn't actually work
- really minor stuff
- drop RFC

Cornelia Huck (2):
  arm/kvm: add support for MTE
  qtests/arm: add some mte tests
