[PATCH v2 kvmtool 0/4] Add support for running protected VMs on arm64

[Will Deacon <will@kernel.org>]

Hi folks,

This is v2 of the patches I previously posted here:

  https://lore.kernel.org/r/20260619115415.5475-1-will@kernel.org

Changes since v1 include:

  * Bail if user specifies less guest memory than the restricted DMA pool.
  * Avoid silently dropping KVM_VM_TYPE_ARM_PROTECTED on old host kernels.
  * Added R-b/T-b tags (thank you!)

The patches are also available here if you want to pull them directly:

Cheers,

Will
