       "A collection of fixes I've been accruing over the last few weeks, none
        of them have been severe enough to warrant flushing the queue but it's
        been long enough now that it's a good idea to send them in.
      
        A handful of them are fixups for QSPI DT/bindings/compatibles, some
        smaller fixes for system DMA clock control and TMU interrupts on i.MX,
        a handful of fixes for OMAP, including a fix for DSI (display) on
        omap5"

      * If the SMM area indicates that SMM interrupted a running guest,
        check that EFER.SVME which is also saved in this area is set, otherwise
        the guest might have tampered with SMM save area, and so indicate
        emulation failure which should triple fault the guest.
      
      * Check that that guest CPUID supports SVM (due to the same issue as above)

      SVM: nSVM: correctly restore GIF on vmexit from nesting after migration · 9883764a
      Maxim Levitsky authored
      Currently code in svm_set_nested_state copies the current vmcb control
      area to L1 control area (hsave->control), under assumption that
      it mostly reflects the defaults that kvm choose, and later qemu
      overrides  these defaults with L2 state using standard KVM interfaces,
      like KVM_SET_REGS.
      
      However nested GIF (which is AMD specific thing) is by default is true,
      and it is copied to hsave area as such.
      
      This alone is not a big deal since on VMexit, GIF is always set to false,
      regardless of what it was on VM entry.  However in nested_svm_vmexit we
      were first were setting GIF to false, but then we overwrite the control
      fields with value from the hsave area.  (including the nested GIF field
      itself if GIF virtualization is enabled).
      
      Now on normal vm entry this is not a problem, since GIF is usually false
      prior to normal vm entry, and this is the value that copied to hsave,
      and then restored, but this is not always the case when the nested state
      is loaded as explained above.
      
      To fix this issue, move svm_set_gif after we restore the L1 control
      state in nested_svm_vmexit, so that even with wrong GIF in the
      saved L1 control area, we still clear GIF as the spec says.

      openrisc: Fix issue with get_user for 64-bit values · d877322b
      Stafford Horne authored
      A build failure was raised by kbuild with the following error.
      
          drivers/android/binder.c: Assembler messages:
          drivers/android/binder.c:3861: Error: unrecognized keyword/register name `l.lwz ?ap,4(r24)'
          drivers/android/binder.c:3866: Error: unrecognized keyword/register name `l.addi ?ap,r0,0'
      
      The issue is with 64-bit get_user() calls on openrisc.  I traced this to
      a problem where in the internally in the get_user macros there is a cast
      to long __gu_val this causes GCC to think the get_user call is 32-bit.
      This binder code is really long and GCC allocates register r30, which
      triggers the issue. The 64-bit get_user asm tries to get the 64-bit pair
      register, which for r30 overflows the general register names and returns
      the dummy register ?ap.
      
      The fix here is to move the temporary variables into the asm macros.  We
      use a 32-bit __gu_tmp for 32-bit and smaller macro and a 64-bit tmp in
      the 64-bit macro.  The cast in the 64-bit macro has a trick of casting
      through __typeof__((x)-(x)) which avoids the below warning.  This was
      barrowed from riscv.
      
          arch/openrisc/include/asm/uaccess.h:240:8: warning: cast to pointer from integer of different size
      
      I tested this in a small unit test to check reading between 64-bit and
      32-bit pointers to 64-bit and 32-bit values in all combinations.  Also I
      ran make C=1 to confirm no new sparse warnings came up.  It all looks
      clean to me.

      x86/kvm: don't forget to ACK async PF IRQ · cc17b225
      Vitaly Kuznetsov authored
      Merge commit 26d05b36 ("Merge branch 'kvm-async-pf-int' into HEAD")
      tried to adapt the new interrupt based async PF mechanism to the newly
      introduced IDTENTRY magic but unfortunately it missed the fact that
      DEFINE_IDTENTRY_SYSVEC() doesn't call ack_APIC_irq() on its own and
      all DEFINE_IDTENTRY_SYSVEC() users have to call it manually.
      
      As the result all multi-CPU KVM guest hang on boot when
      KVM_FEATURE_ASYNC_PF_INT is present. The breakage went unnoticed because no
      KVM userspace (e.g. QEMU) currently set it (and thus async PF mechanism
      is currently disabled) but we're about to change that.
