Linus Torvalds 0e8863244e ARM: ... * Rework heuristics for resolving the fault IPA (HPFAR_EL2 v. re-walk stage-1 page tables) to align with the architecture. This avoids possibly taking an SEA at EL2 on the page table walk or using an architecturally UNKNOWN fault IPA. * Use acquire/release semantics in the KVM FF-A proxy to avoid reading a stale value for the FF-A version. * Fix KVM guest driver to match PV CPUID hypercall ABI. * Use Inner Shareable Normal Write-Back mappings at stage-1 in KVM selftests, which is the only memory type for which atomic instructions are architecturally guaranteed to work. s390: * Don't use %pK for debug printing and tracepoints. x86: * Use a separate subclass when acquiring KVM's per-CPU posted interrupts wakeup lock in the scheduled out path, i.e. when adding a vCPU on the list of vCPUs to wake, to workaround a false positive deadlock. The schedule out code runs with a scheduler lock that the wakeup handler takes in the opposite order; but it does so with IRQs disabled and cannot run concurrently with a wakeup. * Explicitly zero-initialize on-stack CPUID unions * Allow building irqbypass.ko as as module when kvm.ko is a module * Wrap relatively expensive sanity check with KVM_PROVE_MMU * Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accesses selftests: * Add more scenarios to the MONITOR/MWAIT test. * Add option to rseq test to override /dev/cpu_dma_latency * Bring list of exit reasons up to date * Cleanup Makefile to list once tests that are valid on all architectures Other: * Documentation fixes -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmf083IUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroN1dgf/QwfpZcHoMNQSnrc1jMy2LHrArln2 XfmsOGZTU7kyoLQsLWGAPNocOveGdiemTDsj5ZXoNMnqV8hCBr+tZuv2gWI1rr/o kiGerdIgSZ9piTjBlJkVAaOzbWhg2DUnr7qVVzEzFY9+rPNyQ81vgAfU7h56KhYB optecozmBrHHAxvQZwmPeL9UyPWFjOF1BY/8LTMx7X+aVuCX6qx1JqO3a3ylAw4J tGXv6qFJfuCnu1d1b4X0ILce0iMUTOjQzvTcIm+BKjYycecl+3j1aczC/BOorIgc mf0+XeauhcTduK73pirnvx2b05eOxntgkOpwJytO2RP6pE0uK+2Th/C3Qg== =ba/Y -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm fixes from Paolo Bonzini: "ARM: - Rework heuristics for resolving the fault IPA (HPFAR_EL2 v. re-walk stage-1 page tables) to align with the architecture.
