      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.

       1) Off by one and bounds checking fixes in NFC, from Dan Carpenter.
      
       2) There have been many weird regressions in r8169 since we turned ASPM
          support on, some are still not understood nor completely resolved.
          Let's turn this back off for now. From Heiner Kallweit.
      
       3) Signess fixes for ethtool speed value handling, from Michael
          Zhivich.
      
       4) Handle timestamps properly in macb driver, from Paul Thomas.
      
       5) Two erspan fixes, it's the usual "skb ->data potentially reallocated
          and we're holding a stale protocol header pointer". From Lorenzo
          Bianconi.
