      s390/sclp_vt220: Enable ASCII console per default · f2485f5d
      Peter Oberparleiter authored
      When you want to use the HMC's ASCII console as console device for
      a z/VM guest you have to specify console=ttyS1 on the kernel command
      line. But it won't work until you specify conmode=sclp as well.
      This behavior is inconsistent with the use of the ASCII console as
      TTY device which works on z/VM without the need to specify a conmode.
      Fix this inconsistency by removing the check for conmode=sclp in the
      ASCII console registration function.

      s390/qdio: replace shift loop by ilog2 · 92bdae5d
      Fabian Frederick authored
      account_sbals is called by get_inbound_buffer_frontier and
      get_outbound_buffer_frontier with 'count' value > 0 so we can safely
      convert shift loop to ilog2.

      s390/cio: silence lockdep warning · dbe33fc9
      Sebastian Ott authored
      On systems where a ccw based console device is used a lockdep false alarm
      could be triggered when a device driver calls printk while holding a
      subchannels lock (e.g. in it's irq handler). Since this is valid behavior
      fix this by introducing a separate lock class for the console subchannels
      The lockdep warning was revealed by "printk: enable interrupts before calling
      console_trylock_for_printk()" which changed console_unlock() to be called with
      lockdep enabled.

      s390/uaccess: always load the kernel ASCE after task switch · f8b13505
      Martin Schwidefsky authored
      This patch fixes a problem introduced with git commit beef560b
      "s390/uaccess: simplify control register updates".
      The switch_mm function is not called if the next process is a kernel
      thread without an attached mm or is a nop if the mm does not change.
      But CR1 still needs to be loaded with the kernel ASCE in case the
      code returns to a uaccess function that uses the secondary space mode.
      In addition move the set_fs call from finish_arch_switch to
      finish_arch_post_lock_switch and then remove finish_arch_switch.

      Rik van Riel authored
      This function is supposed to return true if the new load imbalance is
      worse than the old one.  It didn't.  I can only hope brown paper bags
      are in style.
      Now things converge much better on both the 4 node and 8 node systems.
      I am not sure why this did not seem to impact specjbb performance on the
      4 node system, which is the system I have full-time access to.
      This bug was introduced recently, with commit e63da036 ("sched/numa:

      Don't trigger congestion wait on dirty-but-not-writeout pages · b738d764
      Linus Torvalds authored
      shrink_inactive_list() used to wait 0.1s to avoid congestion when all
      the pages that were isolated from the inactive list were dirty but not
      under active writeback.  That makes no real sense, and apparently causes
      major interactivity issues under some loads since 3.11.
      The ostensible reason for it was to wait for kswapd to start writing
      pages, but that seems questionable as well, since the congestion wait
      code seems to trigger for kswapd itself as well.  Also, the logic behind
      delaying anything when we haven't actually started writeback is not
      clear - it only delays actually starting that writeback.
      We'll still trigger the congestion waiting if
       (a) the process is kswapd, and we hit pages flagged for immediate
       (b) the process is not kswapd, and the zone backing dev writeback is
           actually congested.
      This probably needs to be revisited, but as it is this fixes a reported

      Input: synaptics - fix resolution for manually provided min/max · d49cb7ae
      Benjamin Tissoires authored
      commit 421e08c4 fixed the reported min/max for the X and Y axis,
      but unfortunately, it broke the resolution of those same axis.
      On the t540p, the resolution is the same regarding X and Y. It is not
      a problem for xf86-input-synaptics because this driver is only interested
      in the ratio between X and Y.
      Unfortunately, xf86-input-cmt uses directly the resolution, and having a
      null resolution leads to some divide by 0 errors, which are translated by
      -infinity in the resulting coordinates.

      The touchpad on the GIGABYTE U2442 not only stops communicating when we try
      to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS
      versions also when we set bit 1 (enable two finger mode auto correct).
      I've asked the original reporter of:
      To check that not setting bit 1 does not lead to any adverse effects on his
      model / BIOS revision, and it does not, so this commit fixes the touchpad
      not working on these versions by simply never setting bit 1 for laptop
      models with the no_hw_res quirk.

      Input: elantech - deal with clickpads reporting right button events · cd9e83e2
      Hans de Goede authored
      At least the Dell Vostro 5470 elantech *clickpad* reports right button
      clicks when clicked in the right bottom area:
      This is different from how (elantech) clickpads normally operate, normally
      no matter where the user clicks on the pad the pad always reports a left
      button event, since there is only 1 hardware button beneath the path.
      It looks like Dell has put 2 buttons under the pad, one under each bottom
      corner, causing this.
      Since this however still clearly is a real clickpad hardware-wise, we still
      want to report it as such to userspace, so that things like finger movement
      in the bottom area can be properly ignored as it should be on clickpads.
      So deal with this weirdness by simply mapping a right click to a left click
      on elantech clickpads. As an added advantage this is something which we can
      simply do on all elantech clickpads, so no need to add special quirks for
      this weird model.

      Robert Woerle authored
      The driver sends 3 bytes instead of 2 when accessing a register on the M09
      firmware, so writing to gain seems to overflow into the offset register.

      Pull clock framework updates from Mike Turquette:
       "The clock framework changes for 3.16 are pretty typical: mostly clock
        driver additions and fixes.  There are additions to the clock core
        code for some of the basic types (e.g. the common divider type has
        some fixes and featured added to it).
        One minor annoyance is a last-minute dependency that wasn't handled
        quite right.  Commit ba0fae3b ("clk: berlin: add core clock driver
        for BG2/BG2CD") in this pull request depends on
        include/dt-bindings/clock/berlin2.h, which is already in your tree via
        the arm-soc pull request.  Building for the berlin platform will break
        when the clk tree is built on it's own, but merged into your master
        branch everything should be fine"
