      Pull KVM updates from Avi Kivity:
       "Highlights of the changes for this release include support for vfio
        level triggered interrupts, improved big real mode support on older
        Intels, a streamlines guest page table walker, guest APIC speedups,
        PIO optimizations, better overcommit handling, and read-only memory."

      firmware: use 'kernel_read()' to read firmware into kernel buffer · ce57e981
      Linus Torvalds authored
      Fengguang correctly points out that the firmware reading should not use
      vfs_read(), since the buffer is in kernel space.
      
      The vfs_read() just happened to work for kernel threads, but sparse
      warns about the incorrect address spaces, and it's definitely incorrect
      and could fail for other users of the firmware loading.
