Subject: [GIT PULL] KVM/arm64 fixes for 5.12, take #2
Date: Fri, 12 Mar 2021 16:00:03 +0000 [thread overview]
Message-ID: <20210312160003.3920996-1-maz@kernel.org> (raw)
Hi Paolo,
Here's the second batch of KVM/arm64 fixes for 5.12. The most notable
item is the tidying up of the way we deal with the guest physical
space, which had a couple of warts. The other patches address i-cache
isolation between vcpus (they are supposed to be vcpu-private, but can
not being so...), and a fix for a link-time issue that can occur with
LTO.
Note that this time around, this pull request is on top of kvm/next,
right after the patches you applied last week.
Please pull,
M.

KVM: arm64: Fix exclusive limit for IPA size (2021-03-12 15:43:22 +0000)
----------------------------------------------------------------
KVM/arm64 fixes for 5.12, take #2
- Fix a couple of branches that could be impossible to resolve at
link time when objects are far apart, such as with LTO
- Mandate i-cache invalidation when two vcpus are sharing a physical CPU
- Fail VM creation if the implicit IPA size isn't supported
- Don't reject memslots that reach the IPA limit without breaching it
----------------------------------------------------------------
