      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.

      powerpc/powernv/npu-dma: Add explicit flush when sending an ATSD · bbd5ff50
      Alistair Popple authored
      NPU2 requires an extra explicit flush to an active GPU PID when
      sending address translation shoot downs (ATSDs) to reliably flush the
      GPU TLB. This patch adds just such a flush at the end of each sequence
      of ATSDs.
      We can safely use PID 0 which is always reserved and active on the
      GPU. PID 0 is only used for init_mm which will never be a user mm on
      the GPU. To enforce this we add a check in pnv_npu2_init_context()
      just in case someone tries to use PID 0 on the GPU.

      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.

      i2c: imx: Use correct function to write to register · 6c782a5e
      Michail Georgios Etairidis authored
      The i2c-imx driver incorrectly uses readb()/writeb() to read and
      write to the appropriate registers when performing a repeated start.
      The appropriate imx_i2c_read_reg()/imx_i2c_write_reg() functions
      should be used instead. Performing a repeated start results in
      a kernel panic. The platform is imx.

      xfs: don't allow bmap on rt files · eb5e248d
      Darrick J. Wong authored
      bmap returns a dumb LBA address but not the block device that goes with
      that LBA.  Swapfiles don't care about this and will blindly assume that
      the data volume is the correct blockdev, which is totally bogus for
      files on the rt subvolume.  This results in the swap code doing IOs to
      arbitrary locations on the data device(!) if the passed in mapping is a
      realtime file, so just turn off bmap for rt files.

      ACPI / scan: Fix enumeration for special SPI and I2C devices · e4330d8b
      Jarkko Nikula authored
      Commit f406270b ("ACPI / scan: Set the visited flag for all
      enumerated devices") caused that two group of special SPI or I2C
      devices do not enumerate. SPI and I2C devices are expected to be
      enumerated by the SPI and I2C subsystems but change caused that
      acpi_bus_attach() marks those devices with acpi_device_set_enumerated().
      First group of devices are matched using Device Tree compatible property
      with special _HID "PRP0001". Those devices have matched scan handler,
      acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them
      with acpi_device_set_enumerated().
      Second group of devices without valid _HID such as "LNXVIDEO" have
      device->pnp.type.platform_id set to zero and change again marks them
      with acpi_device_set_enumerated().
      Fix this by flagging the SPI and I2C devices during struct acpi_device
      object initialization time and let the code in acpi_bus_attach() to go
      through the device_attach() and acpi_default_enumeration() path for all
      SPI and I2C devices.
