       "A number of driver specific fixes (including several missing
        dependencies for randconfig type cases) plus two core fixes.
      
        One makes the setup_transfer() callback optional which unbreaks some
        drivers which had been merged with it omitted due to local versions of
        this patch and another ensures that we don't corrupt data by leaking
        internal dummy buffers to callers, causing the callers to think they
        allocated those buffers"

      iommu/arm-smmu: Fix sign-extension of upstream bus addresses at stage 1 · 5dc5616e
      Will Deacon authored
      Stage 1 translation is controlled by two sets of page tables (TTBR0 and
      TTBR1) which grow up and down from zero respectively in the ARMv8
      translation regime. For the SMMU, we only care about TTBR0 and, in the
      case of a 48-bit virtual space, we expect to map virtual addresses 0x0
      through to 0xffff_ffff_ffff.
      
      Given that some masters may be incapable of emitting virtual addresses
      targetting TTBR1 (e.g. because they sit on a 48-bit bus), the SMMU
      architecture allows bit 47 to be sign-extended, halving the virtual
      range of TTBR0 but allowing TTBR1 to be used. This is controlled by the
      SEP field in TTBCR2.
      
      The SMMU driver incorrectly enables this sign-extension feature, which
      causes problems when userspace addresses are programmed into a master
      device with the SMMU expecting to map the incoming transactions via
      TTBR0; if the top bit of address is set, we will instead get a
      translation fault since TTBR1 walks are disabled in the TTBCR.
      
      This patch fixes the issue by disabling sign-extension of a fixed
      virtual address bit and instead basing the behaviour on the upstream bus
      size: the incoming address is zero extended unless the upstream bus is
      only 49 bits wide, in which case bit 48 is used as the sign bit and is
      replicated to the upper bits.

      spi: Fixes for v4.1
      
      A few driver fixes plus two changes for the core, one to make the
      setup_transfer() callback optional which fixes crashes in some drivers
      which were updated to use new interfaces without apparent testing and
      one to ensure we don't expose the data buffers we use for dummy
      transfers to drivers which avoids potential issues with multiple
      accesses to them or reuse.

      drm: Zero out invalid vblank timestamp in drm_update_vblank_count. · fdb68e09
      Mario Kleiner authored
      Since commit 844b03f2 we make
      sure that after vblank irq off, we return the last valid
      (vblank count, vblank timestamp) pair to clients, e.g., during
      modesets, which is good.
      
      An overlooked side effect of that commit for kms drivers without
      support for precise vblank timestamping is that at vblank irq
      enable, when we update the vblank counter from the hw counter, we
      can't update the corresponding vblank timestamp, so now we have a
      totally mismatched timestamp for the new count to confuse clients.
      
      Restore old client visible behaviour from before Linux 3.17, but
      zero out the timestamp at vblank counter update (instead of disable
      as in original implementation) if we can't generate a meaningful
      timestamp immediately for the new vblank counter. This will fix
      this regression, so callers know they need to retry again later
      if they need a valid timestamp, but at the same time preserves
      the improvements made in the commit mentioned above.
