       "ARM:
         - Fix a VFP corruption in 32-bit guest
         - Add missing cache invalidation for CoW pages
         - Two small cleanups
      
        s390:
         - Fallout from the hugetlbfs support: pfmf interpretion and locking
         - VSIE: fix keywrapping for nested guests
      
        PPC:
         - Fix a bug where pages might not get marked dirty, causing guest
           memory corruption on migration
         - Fix a bug causing reads from guest memory to use the wrong guest
           real address for very large HPT guests (>256G of memory), leading
           to failures in instruction emulation.
      
        x86:
         - Fix out of bound access from malicious pv ipi hypercalls
           (introduced in rc1)
         - Fix delivery of pending interrupts when entering a nested guest,
           preventing arbitrarily late injection
         - Sanitize kvm_stat output after destroying a guest
         - Fix infinite loop when emulating a nested guest page fault and
           improve the surrounding emulation code
         - Two minor cleanups"

      Allwinner fixes for 4.19
      
      Just one fix for H6 mmc on the Pine H64: the mmc bus width was missing
      from the device tree. This was added in 4.19-rc1.

      x86/mm: Use WRITE_ONCE() when setting PTEs · 9bc4f28a
      Nadav Amit authored
      When page-table entries are set, the compiler might optimize their
      assignment by using multiple instructions to set the PTE. This might
      turn into a security hazard if the user somehow manages to use the
      interim PTE. L1TF does not make our lives easier, making even an interim
      non-present PTE a security hazard.
      
      Using WRITE_ONCE() to set PTEs and friends should prevent this potential
      security hazard.
      
      I skimmed the differences in the binary with and without this patch. The
      differences are (obviously) greater when CONFIG_PARAVIRT=n as more
      code optimizations are possible. For better and worse, the impact on the
      binary with this patch is pretty small. Skimming the code did not cause
      anything to jump out as a security hazard, but it seems that at least
      move_soft_dirty_pte() caused set_pte_at() to use multiple writes.

      x86/apic/vector: Make error return value negative · 47b7360c
      Thomas Gleixner authored
      activate_managed() returns EINVAL instead of -EINVAL in case of
      error. While this is unlikely to happen, the positive return value would
      cause further malfunction at the call site.
