Linus, The following changes since commit 009384b38034111bf2c0c7bfb2740f5bd45c176c: irqchip/gic-v4.1: Eagerly vmap vPEs (2020-03-24 12:15:51 +0000) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to 514ccc194971d0649e4e7ec8a9b3a6e33561d7bf: x86/kvm: fix a missing-prototypes "vmread_error" (2020-04-02 15:17:45 -0400) ---------------------------------------------------------------- ARM: * GICv4.1 support * 32bit host removal PPC: * secure (encrypted) using under the Protected Execution Framework ultravisor s390: * allow disabling GISA (hardware interrupt injection) and protected VMs/ultravisor support. x86: * New dirty bitmap flag that sets all bits in the bitmap when dirty page logging is enabled; this is faster because it doesn't require bulk modification of the page tables. * Initial work on making nested SVM event injection more similar to VMX, and less buggy. * Various cleanups to MMU code (though the big ones and related optimizations were delayed to 5.8). Instead of using cr3 in function names which occasionally means eptp, KVM too has standardized on "pgd". * A large refactoring of CPUID features, which now use an array that parallels the core x86_features. * Some removal of pointer chasing from kvm_x86_ops, which will also be switched to static calls as soon as they are available. * New Tigerlake CPUID features. * More bugfixes, optimizations and cleanups. Generic: * selftests: cleanups, new MMU notifier stress test, steal-time test * CSV output for kvm_stat. KVM/MIPS has been broken since 5.5, it does not compile due to a patch committed by MIPS maintainers. I had already prepared a fix, but the MIPS maintainers prefer to fix it in generic code rather than KVM so they are taking care of it. ---------------------------------------------------------------- The branch shows up as based on a random commit because of an ARM topic branch that you have already merged. Most of it was developed as usual in the past couple of months---no rebases or back merges here. However, I also had 4 more patches to split a large file, but git hates resolving that merge ("-X histogram" or "-X patience" make things a little better, but not something that you shoud care about). I will rebase those, retest, and send them separately.
