[RFC PATCH 0/3] arm64: KVM: use increased VA range if needed

[Ard Biesheuvel]

This series addresses the issue where KVM will not be able to initialize
when running on a system whose RAM is located higher in the physical address
space than can be covered with an ID map using VA_BITS of virtual address
space.

Tested on AMD Seattle with 4k pages/VA_BITS==39.

Ard Biesheuvel (3):
  ARM, arm64: kvm: get rid of the bounce page
  arm64: make ID map shareable with EL2
  arm64: KVM: use ID map with increased VA range if required
