      KVM: x86/mmu: Fix an inverted list_empty() check when zapping sptes · cfd32acf
      Sean Christopherson authored
      A recently introduced helper for handling zap vs. remote flush
      incorrectly bails early, effectively leaking defunct shadow pages.
      Manifests as a slab BUG when exiting KVM due to the shadow pages
      being alive when their associated cache is destroyed.

      clang warns about statically defined DMA masks from the DMA_BIT_MASK

      Dear ARM SoC maintainers,
      
      can you please revert this patch. It was the wrong solution to the
      wrong problem, and I must have acted in stress. Andrey fixed the
