[PATCH v5 0/9] KVM: arm64: Fixes for guest CPU feature trapping and enabling

[Fuad Tabba <tabba@google.com>]

Hi,

This series contains several fixes for guest feature trapping and
enabling, as well as a bit of tidying up.

Changes from v3 [1]:
- Add a map of KVM capabilities to IOCTLs (Oliver)
- Based on Linux 6.18-rc6

Cheers,
