      KVM: x86: fix singlestepping over syscall · c8401dda
      Paolo Bonzini authored
      TF is handled a bit differently for syscall and sysret, compared
      to the other instructions: TF is checked after the instruction completes,
      so that the OS can disable #DB at a syscall by adding TF to FMASK.
      When the sysret is executed the #DB is taken "as if" the syscall insn
      just completed.
      
      KVM emulates syscall so that it can trap 32-bit syscall on Intel processors.
      Fix the behavior, otherwise you could get #DB on a user stack which is not
      nice.  This does not affect Linux guests, as they use an IST or task gate
      for #DB.
      
      This fixes CVE-2017-7518.

      KVM: s390: fix shadow table handling for nested guests
      
      Some odd-ball cases (real-space designation ASCEs) are handled wrong
      for the shadow page tables. Fix it.

      KVM: s390: gaccess: fix real-space designation asce handling for gmap shadows · addb63c1
      Heiko Carstens authored
      For real-space designation asces the asce origin part is only a token.
      The asce token origin must not be used to generate an effective
      address for storage references. This however is erroneously done
      within kvm_s390_shadow_tables().
      
      Furthermore within the same function the wrong parts of virtual
      addresses are used to generate a corresponding real address
      (e.g. the region second index is used as region first index).
      
      Both of the above can result in incorrect address translations. Only
      for real space designations with a token origin of zero and addresses
      below one megabyte the translation was correct.
      
      Furthermore replace a "!asce.r" statement with a "!*fake" statement to
      make it more obvious that a specific condition has nothing to do with
      the architecture, but with the fake handling of real space designations.

      Pull block fixes from Jens Axboe:
       "This contains a set of fixes for xen-blkback by way of Konrad, and a
        performance regression fix for blk-mq for shared tags.
      
        The latter could account for as much as a 50x reduction in
        performance, with the test case from the user with 500 name spaces. A
        more realistic setup on my end with 32 drives showed a 3.5x drop. The
        fix has been thoroughly tested before being committed"
