Hi Paolo,
It was good to see you (and everyone else) at KVM Forum this week!
And to celebrate, here's a first batch of fixes for KVM/arm64. A bunch
of them are addressing issues introduced by the invasive changes that
took place in the 5.10 merge window (MM, nVHE host entry). A few
others are addressing some older bugs (VFIO PTE mappings, AArch32
debug, composite huge pages), and a couple of improvements
(HYP-visible capabilities are made more robust).
Please pull,
M.
The following changes since commit 4e5dc64c43192b4fd4c96ac150a8f013065f5f5b:
