Subject: [PATCH v2 0/5] KVM: arm64: Restrict host hypercalls when pKVM is enabled
Date: Tue, 5 Oct 2021 12:37:16 +0100 [thread overview]
Message-ID: <20211005113721.29441-1-will@kernel.org> (raw)
Hi all,
This is version two of the patches I previously posted here:
https://lore.kernel.org/r/20210923112256.15767-1-will@kernel.org
Changes since v2 include:
- Add a comment about pkvm_prot_finalize() returning -EPERM
- Fixed ordering of hypercalls in 'host_hcall' array
- Added reviewed-by tags
Patches based on -rc2. Feedback welcome.
Cheers,
Will
