Pull powerpc fixes from Michael Ellerman:
 "Our recent cleanup of EEH led to an oops on bare metal machines when
  the cxl (CAPI) driver creates virtual devices for an attached FPGA
  accelerator.

  The "secure virtual machine" support we added in v5.4 had a bug if the
  kernel was relocated (moved during boot), in those cases the signature
  of the kernel text wouldn't verify and the Ultravisor would refuse to
  run the VM.

  A recent change to disable interrupts before calling
  arch_cpu_idle_dead() caused a WARN_ON() in our bare metal CPU offline
  code to always trigger.

  The KUAP (SMAP) support we added for 32-bit Book3S had a bug if the
  address range crossed a segment (256MB) boundary which could lead to
  spurious faults.

  Thanks to: Christophe Leroy, Frederic Barrat, Michael Anderson,
  Nicholas Piggin, Sam Bobroff, Thiago Jung Bauermann"

Pull arm64 fixes from Will Deacon:
 "These are almost exclusively related to CPU errata in CPUs from
  Broadcom and Qualcomm where the workarounds were either not being
  enabled when they should have been or enabled when they shouldn't have
  been.

  The only "interesting" fix is ensuring that writeable, shared mappings
  are initially mapped as clean since we inadvertently broke the logic
  back in v4.14 and then noticed the problem via code inspection the
  other day.

  The only critical issue we have outstanding is a sporadic NULL
  dereference in the scheduler, which doesn't appear to be
  arm64-specific and PeterZ is tearing his hair out over it at the
  moment.

  Summary:

   - Enable CPU errata workarounds for Broadcom Brahma-B53

   - Enable CPU errata workarounds for Qualcomm Hydra/Kryo CPUs

   - Fix initial dirty status of writeable, shared mappings"

Pull kvm fixes from Paolo Bonzini:
 "generic:
   - fix memory leak on failure to create VM

  x86:
   - fix MMU corner case with AMD nested paging disabled"

* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  KVM: vmx, svm: always run with EFER.NXE=1 when shadow paging is active
  kvm: call kvm_arch_destroy_vm if vm creation fails
  kvm: Allocate memslots and buses before calling kvm_arch_init_vm

The Broadcom Brahma-B53 core is susceptible to the issue described by
ARM64_ERRATUM_843419 so this commit enables the workaround to be applied
when executing on that core.

Since there are now multiple entries to match, we must convert the
existing ARM64_ERRATUM_843419 into an erratum list and use
cpucap_multi_entry_cap_matches to match our entries.
