Cover letter [PATCH v4 00/15] KVM/arm64: Add NV support for ERET and PAuth
This is the fourth version of this series introducing ERET and PAuth support for NV guests, and now the base prefix for the NV support series.
Unless someone shouts, I intend to take this in for 6.10.
* From v3 [3]
- Check for NV support before checking for HCR_EL2.NV on vpcu exit
- Rebased on 6.9-rc1
* From v2 [2]
- Enforce that both Address and Generic authentication use the same algorithm
- Reduce PAuth trapping by eagerly setting the HCR_EL2.API/APK bits
- Collected RBs, with thanks
- Rebased on kvmarm-6.9
* From v1 [1]:
- Don't repaint the ISS_ERET* definitions, but provide reasonable helpers instead
- Dropped superfluous VNCR_EL2 definition
- Amended comments and creative spelling
