Hi Paolo,
Here's the 5.14 pull request for 5.14. This round, plenty of changes
in the mm department (MTE, CMOs, device mappings, host S2), but also
a lot of work in the selftest infrastructure. On top of that, a few
PMU fixes, and the ability to run guests on the M1...
Note that we carry a branch (arm64/for-next/caches) shared with the
arm64 tree in order to avoid ugly conflicts. You will still get a few
minor ones with the PPC tree, but the resolution is obvious.
Oh, and each merge commit has a full description of what they contain.
Hopefully we won't get yelled at this time.
Please pull,
M.

Merge branch kvm-arm64/mmu/mte into kvmarm-master/next (2021-06-25 14:25:56 +0100)
----------------------------------------------------------------
KVM/arm64 updates for v5.14.
- Add MTE support in guests, complete with tag save/restore interface
- Reduce the impact of CMOs by moving them in the page-table code
- Allow device block mappings at stage-2
- Reduce the footprint of the vmemmap in protected mode
- Support the vGIC on dumb systems such as the Apple M1
- Add selftest infrastructure to support multiple configuration
and apply that to PMU/non-PMU setups
- Add selftests for the debug architecture
- The usual crop of PMU fixes
