Subject: [GIT PULL] KVM/arm64 fixes for 7.0, take #4
Date: Fri, 20 Mar 2026 09:41:51 +0000 [thread overview]
Message-ID: <20260320094151.2541661-1-maz@kernel.org> (raw)
Paolo,
Another week, another set of fixes. This time, another two fixes,
mostly observable with nested virt. The first one results in a vcpu
coming out of reset potentially skipping the first instruction at its
initial PC. The second one is a classic example of pointer arithmetic
going wrong in our address translation emulation, setting the access
bit in semi-random places. Both are stable candidates.
Please pull,
M.

KVM: arm64: Fix the descriptor address in __kvm_at_swap_desc() (2026-03-17 13:40:00 +0000)
----------------------------------------------------------------
KVM/arm64 fixes for 7.0, take #4
- Clear the pending exception state from a vcpu coming out of
reset, as it could otherwise affect the first instruction
executed in the guest.
- Fix the address translation emulation icode to set the Hardware
Access bit on the correct PTE instead of some other location.
