      USB: dummy-hcd: bandwidth limits for non-bulk transfers · ffc4ea79
      Alan Stern authored
      Part of the emulation performed by dummy-hcd is accounting for
      bandwidth utilization.  The total amount of data transferred in a
      single frame is supposed to be no larger than an actual USB connection
      could accommodate.
      
      Currently the driver performs bandwidth limiting only for bulk
      transfers; control and periodic transfers are effectively unlimited.
      (Presumably drivers were not expected to request extremely large
      control or interrupt transfers.)  This patch improves the situation
      somewhat by restricting them as well.
      
      The emulation still isn't perfect.  On a real system, even 0-length
      transfers use some bandwidth because of transaction overhead
      (IN, OUT, ACK, NACK packets) and packet overhead (SYNC, PID, bit
      stuffing, CRC, EOP).  Adding in those factors is left as an exercise
      for a later patch.

       "The watchdog (hard/softlockup detector) code is pretty much broken in
        its current state. The patch series addresses this by removing all
        duct tape and refactoring it into a workable state.
      
        The reasons why I ask for inclusion that late in the cycle are:
      
         1) The code causes lockdep splats vs. hotplug locking which get
            reported over and over. Unfortunately there is no easy fix.
      
         2) The risk of breakage is minimal because it's already broken
      
         3) As 4.14 is a long term stable kernel, I prefer to have working
            watchdog code in that and the lockdep issues resolved. I wouldn't
            ask you to pull if 4.14 wouldn't be a LTS kernel or if the
            solution would be easy to backport.
      
         4) The series was around before the merge window opened, but then got
            delayed due to the UP failure caused by the for_each_cpu()
            surprise which we discussed recently.
      
        Changes vs. V1:
      
         - Addressed your review points
      
         - Addressed the warning in the powerpc code which was discovered late
      
         - Changed two function names which made sense up to a certain point
           in the series. Now they match what they do in the end.
      
         - Fixed a 'unused variable' warning, which got not detected by the
           intel robot. I triggered it when trying all possible related config
           combinations manually. Randconfig testing seems not random enough.
      
        The changes have been tested by and reviewed by Don Zickus and tested
        and acked by Micheal Ellerman for powerpc"

      arm64: Ensure fpsimd support is ready before userspace is active · ae2e972d
      Suzuki K Poulose authored
      We register the pm/hotplug callbacks for FPSIMD as late_initcall,
      which happens after the userspace is active (from initramfs via
      populate_rootfs, a rootfs_initcall). Make sure we are ready even
      before the userspace could potentially use it, by promoting to
      a core_initcall.

      arm64: Ensure the instruction emulation is ready for userspace · c0d8832e
      Suzuki K Poulose authored
      We trap and emulate some instructions (e.g, mrs, deprecated instructions)
      for the userspace. However the handlers for these are registered as
      late_initcalls and the userspace could be up and running from the initramfs
      by that time (with populate_rootfs, which is a rootfs_initcall()). This
      could cause problems for the early applications ending up in failure
      like :
      
      [   11.152061] modprobe[93]: undefined instruction: pc=0000ffff8ca48ff4
      
      This patch promotes the specific calls to core_initcalls, which are
      guaranteed to be completed before we hit userspace.

      powerpc/powernv: Increase memory block size to 1GB on radix · 53ecde0b
      Anton Blanchard authored
      Memory hot unplug on PowerNV radix hosts is broken. Our memory block
      size is 256MB but since we map the linear region with very large
      pages, each pte we tear down maps 1GB.
      
      A hot unplug of one 256MB memory block results in 768MB of memory
      getting unintentionally unmapped. At this point we are likely to oops.
      
      Fix this by increasing our memory block size to 1GB on PowerNV radix
      hosts.

      dm raid: fix incorrect status output at the end of a "recover" process · 41dcf197
      Jonathan Brassow authored
      There are three important fields that indicate the overall health and
      status of an array: dev_health, sync_ratio, and sync_action.  They tell
      us the condition of the devices in the array, and the degree to which
      the array is synchronized.
      
      This commit fixes a condition that is reported incorrectly.  When a member
      of the array is being rebuilt or a new device is added, the "recover"
      process is used to synchronize it with the rest of the array.  When the
      process is complete, but the sync thread hasn't yet been reaped, it is
      possible for the state of MD to be:
       mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
       curr_resync_completed = <max dev size> (but not MaxSector)
       and all rdevs to be In_sync.
      This causes the 'array_in_sync' output parameter that is passed to
      rs_get_progress() to be computed incorrectly and reported as 'false' --
      or not in-sync.  This in turn causes the dev_health status characters to
      be reported as all 'a', rather than the proper 'A'.
      
      This can cause erroneous output for several seconds at a time when tools
      will want to be checking the condition due to events that are raised at
      the end of a sync process.  Fix this by properly calculating the
      'array_in_sync' return parameter in rs_get_progress().
      
      Also, remove an unnecessary intermediate 'recovery_cp' variable in
      rs_get_progress().

      KVM: add X86_LOCAL_APIC dependency · e42eef4b
      Arnd Bergmann authored
      The rework of the posted interrupt handling broke building without
      support for the local APIC:
      
      ERROR: "boot_cpu_physical_apicid" [arch/x86/kvm/kvm-intel.ko] undefined!
      
      That configuration is probably not particularly useful anyway, so
      we can avoid the randconfig failures by adding a Kconfig dependency.

      ovl: fix regression caused by exclusive upper/work dir protection · 85fdee1e
      Amir Goldstein authored
      Enforcing exclusive ownership on upper/work dirs caused a docker
      regression: https://github.com/moby/moby/issues/34672.
      
      Euan spotted the regression and pointed to the offending commit.
      Vivek has brought the regression to my attention and provided this
      reproducer:
      
      Terminal 1:
      
        mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
              merged/
      
      Terminal 2:
      
        unshare -m
      
      Terminal 1:
      
        umount merged
        mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
              merged/
        mount: /root/overlay-testing/merged: none already mounted or mount point
               busy
      
      To fix the regression, I replaced the error with an alarming warning.
      With index feature enabled, mount does fail, but logs a suggestion to
      override exclusive dir protection by disabling index.
      Note that index=off mount does take the inuse locks, so a concurrent
      index=off will issue the warning and a concurrent index=on mount will fail.
      
      Documentation was updated to reflect this change.
