The main culprit is a reorganization of the AMD assembly trampoline, allowing percpu variables to be accessed early. This is needed for the return stack depth tracking retbleed mitigation that will be in 6.2, but it also makes it possible to tighten the IBRS restore on vmexit. The latter change is a long tail of the spectrev2/retbleed patches (the corresponding Intel change was simpler and went in already last June), which is why I am including it right now instead of sharing a topic branch with tip. Being assembly and being rich in comments makes the line count balloon a bit, but I am pretty confident in the change (famous last words) because the reorganization actually makes everything simpler and more understandable than before. It has also had external review and has been tested on the aforementioned 6.2 changes, which explode quite brutally without the fix. Apart from this, things are pretty normal. s390: - PCI fix - PV clock fix x86: - Fix clash between PMU MSRs and other MSRs - Prepare SVM assembly trampoline for 6.2 retbleed mitigation and for... - ... tightening IBRS restore on vmexit, moving it before the first RET or indirect branch - Fix log level for VMSA dump - Block all page faults during kvm_zap_gfn_range() Tools: - kvm_stat: fix incorrect detection of debugfs - kvm_stat: update vmexit definitions" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: x86/mmu: Block all page faults during kvm_zap_gfn_range() KVM: x86/pmu: Limit the maximum number of supported AMD GP counters KVM: x86/pmu: Limit the maximum number of supported Intel GP counters KVM: x86/pmu: Do not speculatively query Intel GP PMCs that don't exist yet KVM: SVM: Only dump VMSA to klog at KERN_DEBUG level tools/kvm_stat: update exit reasons for vmx/svm/aarch64/userspace tools/kvm_stat: fix incorrect detection of debugfs x86, KVM: remove unnecessary argument to x86_virt_spec_ctrl and callers KVM: SVM: move MSR_IA32_SPEC_CTRL save/restore to assembly KVM: SVM: restore host save area from assembly KVM: SVM: move guest vmsave/vmload back to assembly KVM: SVM: do not allocate struct svm_cpu_data dynamically KVM: SVM: remove dead field from struct svm_cpu_data KVM: SVM: remove unused field from struct vcpu_svm KVM: SVM: retrieve VMCB from assembly KVM: SVM: adjust register allocation for __svm_vcpu_run() KVM: SVM: replace regs argument of __svm_vcpu_run() with vcpu_svm KVM: x86: use a separate asm-offsets.c file KVM: s390: pci: Fix allocation size of aift kzdev elements KVM: s390: pv: don't allow userspace to set the clock under PV |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
