      drm/i915/gt: Avoid resetting ring->head outside of its timeline mutex · 15de9cb5
      Chris Wilson authored
      We manipulate ring->head while active in i915_request_retire underneath
      the timeline manipulation. We cannot rely on a stable ring->head outside
      of the timeline->mutex, in particular while setting up the context for
      resume and reset.
      
      Closes: https://gitlab.freedesktop.org/drm/intel/issues/1126

      drm/i915/execlists: Always force a context reload when rewinding RING_TAIL · b1339eca
      Chris Wilson authored
      If we rewind the RING_TAIL on a context, due to a preemption event, we
      must force the context restore for the RING_TAIL update to be properly
      handled. Rather than note which preemption events may cause us to rewind
      the tail, compare the new request's tail with the previously submitted
      RING_TAIL, as it turns out that timeslicing was causing unexpected
      rewinds.

          page-flags: define PG_reserved behavior on compound pages
      
          As far as I can see there's no users of PG_reserved on compound pages.
          Let's use PF_NO_COMPOUND here.
      
      drm_pci_alloc has been declared broken since it mixes GFP_COMP and
      SetPageReserved. Avoid this conflict by weaning ourselves off using the
      abstraction and using the dma functions directly.

      bus: moxtet: fix potential stack buffer overflow · 3bf3c974
      Marek Behún authored
      The input_read function declares the size of the hex array relative to
      sizeof(buf), but buf is a pointer argument of the function. The hex
      array is meant to contain hexadecimal representation of the bin array.

      ext4: improve explanation of a mount failure caused by a misconfigured kernel · d65d87a0
      Theodore Ts'o authored
      If CONFIG_QFMT_V2 is not enabled, but CONFIG_QUOTA is enabled, when a
      user tries to mount a file system with the quota or project quota
      enabled, the kernel will emit a very confusing messsage:
      
          EXT4-fs warning (device vdc): ext4_enable_quotas:5914: Failed to enable quota tracking (type=0, err=-3). Please run e2fsck to fix.
          EXT4-fs (vdc): mount failed
      
      We will now report an explanatory message indicating which kernel
      configuration options have to be enabled, to avoid customer/sysadmin
      confusion.
