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. The following changes since commit 357ad203d45c0f9d76a8feadbd5a1c5d460c638b: KVM: arm64: Fix range alignment when walking page tables (2021-03-06 04:18:41 -0500) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-fixes-5.12-2 for you to fetch changes up to 262b003d059c6671601a19057e9fe1a5e7f23722: 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 ---------------------------------------------------------------- Marc Zyngier (3): KVM: arm64: Ensure I-cache isolation between vcpus of a same VM KVM: arm64: Reject VM creation when the default IPA size is unsupported KVM: arm64: Fix exclusive limit for IPA size Sami Tolvanen (1): KVM: arm64: Don't use cbz/adr with external symbols Documentation/virt/kvm/api.rst | 3 +++ arch/arm64/include/asm/kvm_asm.h | 4 ++-- arch/arm64/kvm/arm.c | 7 ++++++- arch/arm64/kvm/hyp/entry.S | 6 ++++-- arch/arm64/kvm/hyp/nvhe/hyp-main.c | 6 +++--- arch/arm64/kvm/hyp/nvhe/tlb.c | 3 ++- arch/arm64/kvm/hyp/vhe/tlb.c | 3 ++- arch/arm64/kvm/mmu.c | 3 +-- arch/arm64/kvm/reset.c | 12 ++++++++---- 9 files changed, 31 insertions(+), 16 deletions(-)
