           of a heroic effort to deobfuscate a decade old spaghetti asm code

         - various other fixes and cleanups
      
        By their nature many of these changes are risky - we tried to test
        them well on many different x86 systems (there are no known
        regressions), and they are split up finely to help bisection - but
        there's still a fair bit of residual risk left so caveat emptor"

      iscsi target: fix oops when adding reject pdu · b815fc12
      Mike Christie authored
      This fixes a oops due to a double list add when adding a reject PDU for
      iscsit_allocate_iovecs allocation failures. The cmd has already been
      added to the conn_cmd_list in iscsit_setup_scsi_cmd, so this has us call
      iscsit_reject_cmd.
      
      Note that for ERL0 the reject PDU is not actually sent, so this patch
      is not completely tested. Just verified we do not oops. The problem is the
      add reject functions return -1 which is returned all the way up to
      iscsi_target_rx_thread which for ERL0 will drop the connection.

      KVM: use slowpath for cross page cached accesses · ca3f0874
      Radim Krčmář authored
      kvm_write_guest_cached() does not mark all written pages as dirty and
      code comments in kvm_gfn_to_hva_cache_init() talk about NULL memslot
      with cross page accesses.  Fix all the easy way.
      
      The check is '<= 1' to have the same result for 'len = 0' cache anywhere
      in the page.  (nr_pages_needed is 0 on page boundary.)
      
      Fixes: 8f964525 ("KVM: Allow cross page reads and writes from cached translations.")
