Hi Paolo, Here's a bunch of fixes that cropped up during the merge window, mostly falling into two categories: 32bit system register accesses, and 64bit pointer authentication handling. Please pull, M. The following changes since commit 8f7f4fe756bd5cfef73cf8234445081385bdbf7d: KVM: arm64: Drop obsolete comment about sys_reg ordering (2020-05-28 13:16:57 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-fixes-5.8-1 for you to fetch changes up to 15c99816ed9396c548eed2e84f30c14caccad1f4: Merge branch 'kvm-arm64/ptrauth-fixes' into kvmarm-master/next (2020-06-10 19:10:40 +0100) ---------------------------------------------------------------- KVM/arm64 fixes for Linux 5.8, take #1 * 32bit VM fixes: - Fix embarassing mapping issue between AArch32 CSSELR and AArch64 ACTLR - Add ACTLR2 support for AArch32 - Get rid of the useless ACTLR_EL1 save/restore - Fix CP14/15 accesses for AArch32 guests on BE hosts - Ensure that we don't loose any state when injecting a 32bit exception when running on a VHE host * 64bit VM fixes: - Fix PtrAuth host saving happening in preemptible contexts - Optimize PtrAuth lazy enable - Drop vcpu to cpu context pointer - Fix sparse warnings for HYP per-CPU accesses ---------------------------------------------------------------- James Morse (3): KVM: arm64: Stop writing aarch32's CSSELR into ACTLR KVM: arm64: Add emulation for 32bit guests accessing ACTLR2 KVM: arm64: Stop save/restoring ACTLR_EL1 Marc Zyngier (9): KVM: arm64: Flush the instruction cache if not unmapping the VM on reboot KVM: arm64: Save the host's PtrAuth keys in non-preemptible context KVM: arm64: Handle PtrAuth traps early KVM: arm64: Stop sparse from moaning at __hyp_this_cpu_ptr KVM: arm64: Remove host_cpu_context member from vcpu structure KVM: arm64: Make vcpu_cp1x() work on Big Endian hosts KVM: arm64: Synchronize sysreg state on injecting an AArch32 exception KVM: arm64: Move hyp_symbol_addr() to kvm_asm.h Merge branch 'kvm-arm64/ptrauth-fixes' into kvmarm-master/next arch/arm64/include/asm/kvm_asm.h | 33 ++++++++++++++++-- arch/arm64/include/asm/kvm_emulate.h | 6 ---- arch/arm64/include/asm/kvm_host.h | 9 +++-- arch/arm64/include/asm/kvm_mmu.h | 20 ----------- arch/arm64/kvm/aarch32.c | 28 ++++++++++++++++ arch/arm64/kvm/arm.c | 20 ++++++----- arch/arm64/kvm/handle_exit.c | 32 ++---------------- arch/arm64/kvm/hyp/debug-sr.c | 4 +-- arch/arm64/kvm/hyp/switch.c | 65 ++++++++++++++++++++++++++++++++++-- arch/arm64/kvm/hyp/sysreg-sr.c | 8 ++--- arch/arm64/kvm/pmu.c | 8 ++--- arch/arm64/kvm/sys_regs.c | 25 +++++++------- arch/arm64/kvm/sys_regs_generic_v8.c | 10 ++++++ 13 files changed, 171 insertions(+), 97 deletions(-)
