      Pull btrfs fixes from David Sterba:
       "Regression fixes in zone activation:
      
         - move a loop invariant out of the loop to avoid checking space
           status
      
         - properly handle unlimited activation
      
        Other fixes:
      
         - for subpage, force the free space v2 mount to avoid a warning and
           make it easy to switch a filesystem on different page size systems
      
         - export sysfs status of exclusive operation 'balance paused', so the
           user space tools can recognize it and allow adding a device with
           paused balance
      
         - fix assertion failure when logging directory key range item"

      Pull RISC-V fix from Palmer Dabbelt:
      
       - A fix to relocate the DTB early in boot, in cases where the
         bootloader doesn't put the DTB in a region that will end up
         mapped by the kernel.
      
         This manifests as a crash early in boot on a handful of
         configurations.

      KVM: VMX: Exit to userspace if vCPU has injected exception and invalid state · 053d2290
      Sean Christopherson authored
      Exit to userspace with an emulation error if KVM encounters an injected
      exception with invalid guest state, in addition to the existing check of
      bailing if there's a pending exception (KVM doesn't support emulating
      exceptions except when emulating real mode via vm86).
      
      In theory, KVM should never get to such a situation as KVM is supposed to
      exit to userspace before injecting an exception with invalid guest state.
      But in practice, userspace can intervene and manually inject an exception
      and/or stuff registers to force invalid guest state while a previously
      injected exception is awaiting reinjection.

      KVM: SEV: Mark nested locking of vcpu->lock · 0c2c7c06
      Peter Gonda authored
      svm_vm_migrate_from() uses sev_lock_vcpus_for_migration() to lock all
      source and target vcpu->locks. Unfortunately there is an 8 subclass
      limit, so a new subclass cannot be used for each vCPU. Instead maintain
      ownership of the first vcpu's mutex.dep_map using a role specific
      subclass: source vs target. Release the other vcpu's mutex.dep_maps.
      
      Fixes: b5663931 ("KVM: SEV: Add support for SEV intra host migration")
