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
