Subject: [PATCH v2 00/13] KVM/arm64: Add NV support for ERET and PAuth
Date: Mon, 26 Feb 2024 10:05:48 +0000 [thread overview]
Message-ID: <20240226100601.2379693-1-maz@kernel.org> (raw)
This is the second version of this series introducing ERET and PAuth
support for NV guests, and now the base prefix for the NV support
series.
Thanks to Joey for reviewing the first half of the series and
providing valuable suggestions, much appreciated!
* 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
