      mm, vmstat: Remove spurious WARN() during zoneinfo print · 8d35bb31
      Reza Arbab authored
      After commit e2ecc8a7 ("mm, vmstat: print non-populated zones in
      zoneinfo"), /proc/zoneinfo will show unpopulated zones.
      
      A memoryless node, having no populated zones at all, was previously
      ignored, but will now trigger the WARN() in is_zone_first_populated().
      
      Remove this warning, as its only purpose was to warn of a situation that
      has since been enabled.
      
      Aside: The "per-node stats" are still printed under the first populated
      zone, but that's not necessarily the first stanza any more.  I'm not
      sure which criteria is more important with regard to not breaking
      parsers, but it looks a little weird to the eye.
      
      Fixes:  e2ecc8a7 ("mm, vmstat: print node-based stats in zoneinfo file")

      time: delete current_fs_time() · 572e0ca9
      Deepa Dinamani authored
      All uses of the current_fs_time() function have been replaced by other
      time interfaces.
      
      And, its use cases can be fulfilled by current_time() or ktime_get_*
      variants.

      hwpoison, memcg: forcibly uncharge LRU pages · 18365225
      Michal Hocko authored
      Laurent Dufour has noticed that hwpoinsoned pages are kept charged.  In
      his particular case he has hit a bad_page("page still charged to
      cgroup") when onlining a hwpoison page.  While this looks like something
      that shouldn't happen in the first place because onlining hwpages and
      returning them to the page allocator makes only little sense it shows a
      real problem.
      
      hwpoison pages do not get freed usually so we do not uncharge them (at
      least not since commit 0a31bc97 ("mm: memcontrol: rewrite uncharge
      API")).  Each charge pins memcg (since e8ea14cc ("mm: memcontrol:
      take a css reference for each charged page")) as well and so the
      mem_cgroup and the associated state will never go away.  Fix this leak
      by forcibly uncharging a LRU hwpoisoned page in delete_from_lru_cache().
      We also have to tweak uncharge_list because it cannot rely on zero ref
      count for these pages.

      Pull thermal management updates from Zhang Rui:
      
       - Fix a problem where orderly_shutdown() is called for multiple times
         due to multiple critical overheating events raised in a short period
         by platform thermal driver. (Keerthy)
      
       - Introduce a backup thermal shutdown mechanism, which invokes
         kernel_power_off()/emergency_restart() directly, after
         orderly_shutdown() being issued for certain amount of time(specified
         via Kconfig). This is useful in certain conditions that userspace may
         be unable to power off the system in a clean manner and leaves the
         system in a critical state, like in the middle of driver probing
         phase. (Keerthy)
      
       - Introduce a new interface in thermal devfreq_cooling code so that the
         driver can provide more precise data regarding actual power to the
         thermal governor every time the power budget is calculated. (Lukasz
         Luba)
      
       - Introduce BCM 2835 soc thermal driver and northstar thermal driver,
         within a new sub-folder. (Rafał Miłecki)
      
       - Introduce DA9062/61 thermal driver. (Steve Twiss)
      
       - Remove non-DT booting on TI-SoC driver. Also add support to fetching
         coefficients from DT. (Keerthy)
      
       - Refactorf RCAR Gen3 thermal driver. (Niklas Söderlund)

       "Things were a lot more calm than previously expected. It's primarily
        fixes in various areas, with most of the new functionality centering
        around TCMU backend driver work that Xiubo Li has been driving.
      
        Here's the summary on the feature side:
      
         - Make T10-PI verify configurable for emulated (FILEIO + RD) backends
          (Dmitry Monakhov)
         - Allow target-core/TCMU pass-through to use in-kernel SPC-PR logic
          (Bryant Ly + MNC)
         - Add TCMU support for growing ring buffer size (Xiubo Li + MNC)
         - Add TCMU support for global block data pool (Xiubo Li + MNC)
      
        and on the bug-fix side:
      
         - Fix COMPARE_AND_WRITE non GOOD status handling for READ phase
          failures (Gary Guo + nab)
         - Fix iscsi-target hang with explicitly changing per NodeACL
          CmdSN number depth with concurrent login driven session
          reinstatement.  (Gary Guo + nab)
         - Fix ibmvscsis fabric driver ABORT task handling (Bryant Ly)
         - Fix target-core/FILEIO zero length handling (Bart Van Assche)
      
        Also, there was an OOPs introduced with the WRITE_VERIFY changes that
        I ended up reverting at the last minute, because as not unusual Bart
        and I could not agree on the fix in time for -rc1. Since it's specific
        to a conformance test, it's been reverted for now.
      
        There is a separate patch in the queue to address the underlying
        control CDB write overflow regression in >= v4.3 separate from the
        WRITE_VERIFY revert here, that will be pushed post -rc1"

       "The change to the Linux page table geometry was delayed for more
        testing with 16G pages, and there's the new CPU features stuff which
        just needed one more polish before going in. Plus a few changes from
        Scott which came in a bit late. And then various fixes, mostly minor.
      
        Summary highlights:
      
         - rework the Linux page table geometry to lower memory usage on
           64-bit Book3S (IBM chips) using the Hash MMU.
      
         - support for a new device tree binding for discovering CPU features
           on future firmwares.
      
         - Freescale updates from Scott:
            "Includes a fix for a powerpc/next mm regression on 64e, a fix for
             a kernel hang on 64e when using a debugger inside a relocated

      sound: Disable the build of OSS drivers · 31cbee6a
      Takashi Iwai authored
      OSS drivers are left as badly unmaintained, and now we're facing a
      problem to clean up the hackish set_fs() usage in their codes.  Since
      most of drivers have been covered by ALSA, and the others are dead old
      and inactive, let's leave them RIP.
      
      This patch is the first step: disable the build of OSS drivers.
      We'll eventually drop the whole codes and clean up later.
      
      Note that sound/oss/dmasound is still kept, since it's a completely
      different implementation of OSS, and it doesn't suffer from set_fs()
      hack.  Moreover, the build of ALSA is disabled on M68K by some reason,
      thus disabling it shall result in a regression.  This one will be
      disabled / removed once when we add the support in ALSA side.

      drm/i915: Make vblank evade warnings optional · 7b8cd336
      Ville Syrjälä authored
      Add a new Kconfig option to enable/disable the extra warnings
      from the vblank evade code. For now we'll keep the warning
      about an actually missed vblank always enabled as that can have
      an actual user visible impact. But if we miss the deadline
      othrwise there's no real need to bother the user with that.
      We'll want these warnings enabled during development however
      so that we can catch regressions.
      
      Based on the reports it looks like this is still very easy
      to hit on SKL, so we have more work ahead of us to optimize
      the crtiical section further.

      Ben Skeggs authored
      The idea here was to avoid having to "manually" program the HW if there's
      a new earliest alarm.  This was lazy and bad, as it leads to loads of fun
      races between inter-related callers (ie. therm).
      
      Turns out, it's not so difficult after all.  Go figure ;)

         - The previous blk-mq hot unplug lock reversal depends on the CPU
           hotplug rework that isn't in mainline yet. This caused a lockdep
           splat when people unplugged CPUs with blk-mq devices. From Wanpeng.

      xen: adjust early dom0 p2m handling to xen hypervisor behavior · 69861e0a
      Juergen Gross authored
      When booted as pv-guest the p2m list presented by the Xen is already
      mapped to virtual addresses. In dom0 case the hypervisor might make use
      of 2M- or 1G-pages for this mapping. Unfortunately while being properly
      aligned in virtual and machine address space, those pages might not be
      aligned properly in guest physical address space.
      
      So when trying to obtain the guest physical address of such a page
      pud_pfn() and pmd_pfn() must be avoided as those will mask away guest
      physical address bits not being zero in this special case.
