      Sergei Shtylyov contributes 5 patches for the rcar_can driver, fixing the IRQ
      check and several info and error messages. There are two patches by J.D.
      Schroeder and Roger Quadros for the c_can driver and dra7x-evm device tree,
      which precent a glitch in the DCAN1 pinmux. Oliver Hartkopp provides a better
      approach to make the CAN skbs unique, the timestamp is replaced by a counter.

      Revert "drm/i915: Use crtc_state->active in primary check_plane func" · 01e2d062
      Linus Torvalds authored
      This reverts commit dec4f799.
      
      Jörg Otte reports a NULL pointder dereference due to this commit, as
      'crtc_state' very much can be NULL:
      
              crtc_state = state->base.state ?
                      intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL;
      
      So the change to test 'crtc_state->base.active' cannot possibly be
      correct as-is.
      
      There may be some other minimal fix (like just checking crtc_state for
      NULL), but I'm just reverting it now for the rc2 release, and people
      like Daniel Vetter who actually know this code will figure out what the
      right solution is in the longer term.

      can: replace timestamp as unique skb attribute · d3b58c47
      Oliver Hartkopp authored
      Commit 514ac99c "can: fix multiple delivery of a single CAN frame for
      overlapping CAN filters" requires the skb->tstamp to be set to check for
      identical CAN skbs.
      
      Without timestamping to be required by user space applications this timestamp
      was not generated which lead to commit 36c01245 "can: fix loss of CAN frames
      in raw_rcv" - which forces the timestamp to be set in all CAN related skbuffs
      by introducing several __net_timestamp() calls.
      
      This forces e.g. out of tree drivers which are not using alloc_can{,fd}_skb()
      to add __net_timestamp() after skbuff creation to prevent the frame loss fixed
      in mainline Linux.
      
      This patch removes the timestamp dependency and uses an atomic counter to
      create an unique identifier together with the skbuff pointer.
      
      Btw: the new skbcnt element introduced in struct can_skb_priv has to be
      initialized with zero in out-of-tree drivers which are not using
      alloc_can{,fd}_skb() too.

      ARM: dts: dra7x-evm: Prevent glitch on DCAN1 pinmux · 2acb5c30
      Roger Quadros authored
      Driver core sets "default" pinmux on on probe and CAN driver
      sets "sleep" pinmux during register. This causes a small window
      where the CAN pins are in "default" state with the DCAN module
      being disabled.
      
      Change the "default" state to be like sleep so this glitch is
      avoided. Add a new "active" state that is used by the driver
      when CAN is actually active.

      can: c_can: Fix default pinmux glitch at init · 03336519
      J.D. Schroeder authored
      The previous change 3973c526 (net: can: c_can: Disable pins when CAN
      interface is down) causes a slight glitch on the pinctrl settings when used.
      Since commit ab78029e (drivers/pinctrl: grab default handles from device core),
      the device core will automatically set the default pins. This causes the pins
      to be momentarily set to the default and then to the sleep state in
      register_c_can_dev(). By adding an optional "enable" state, boards can set the
      default pin state to be disabled and avoid the glitch when the switch from
      default to sleep first occurs. If the "enable" state is not available
      c_can_pinctrl_select_state() falls back to using the "default" pinctrl state.
      
      [Roger Q] - Forward port to v4.2 and use pinctrl_get_select().

      can: rcar_can: fix IRQ check · 5e63e6ba
      Sergei Shtylyov authored
      rcar_can_probe() regards 0 as a wrong IRQ #, despite platform_get_irq() that it
      calls returns negative error code in that case. This leads to the following
      being printed to the console when attempting to open the device:
      
      error requesting interrupt fffffffa
      
      because  rcar_can_open() calls request_irq() with a negative IRQ #, and that
      function naturally fails with -EINVAL.
      
      Check for the negative error codes instead and propagate them upstream instead
      of just returning -ENODEV.

      freeing unlinked file indefinitely delayed · 75a6f82a
      Al Viro authored
      	Normally opening a file, unlinking it and then closing will have
      the inode freed upon close() (provided that it's not otherwise busy and
      has no remaining links, of course).  However, there's one case where that
      does *not* happen.  Namely, if you open it by fhandle with cold dcache,
      then unlink() and close().
      
      	In normal case you get d_delete() in unlink(2) notice that dentry
      is busy and unhash it; on the final dput() it will be forcibly evicted from
      dcache, triggering iput() and inode removal.  In this case, though, we end
      up with *two* dentries - disconnected (created by open-by-fhandle) and
      regular one (used by unlink()).  The latter will have its reference to inode
      dropped just fine, but the former will not - it's considered hashed (it
      is on the ->s_anon list), so it will stay around until the memory pressure
      will finally do it in.  As the result, we have the final iput() delayed
      indefinitely.  It's trivial to reproduce -
      
      void flush_dcache(void)
      {
              system("mount -o remount,rw /");
      }
      
      static char buf[20 * 1024 * 1024];
      
      main()
      {
              int fd;
              union {
                      struct file_handle f;
                      char buf[MAX_HANDLE_SZ];
              } x;
              int m;
      
              x.f.handle_bytes = sizeof(x);
              chdir("/root");
              mkdir("foo", 0700);
              fd = open("foo/bar", O_CREAT | O_RDWR, 0600);
              close(fd);
              name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0);
              flush_dcache();
              fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR);
              unlink("foo/bar");
              write(fd, buf, sizeof(buf));
              system("df .");			/* 20Mb eaten */
              close(fd);
              system("df .");			/* should've freed those 20Mb */
              flush_dcache();
              system("df .");			/* should be the same as #2 */
      }
      
      will spit out something like
      Filesystem     1K-blocks   Used Available Use% Mounted on
      /dev/root         322023 303843      1131 100% /
      Filesystem     1K-blocks   Used Available Use% Mounted on
      /dev/root         322023 303843      1131 100% /
      Filesystem     1K-blocks   Used Available Use% Mounted on
      /dev/root         322023 283282     21692  93% /
      - inode gets freed only when dentry is finally evicted (here we trigger
      than by remount; normally it would've happened in response to memory
      pressure hell knows when).

      There is no need to abort attribute setting or object addition, if the

      Thus, abort these two transactions only if the error is not -EOPNOTSUPP.

      net: bcmgenet: fix accounting of packet drops vs errors · c590032f
      Petri Gynther authored
      bcmgenet driver needs to separate packet drops from packet errors.
      
      When the driver has to drop a *good* packet, due to lack of buffers or
      replacement skbs, increment only dev->stats.[rx|tx]_dropped.
      
      When the driver encounters a bad Rx packet or Tx error, increment only
      dev->stats.[rx|tx]_errors + relevant detailed error counter.

      Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm · 59c3cb55
      Linus Torvalds authored
      Pull libnvdimm fixes from Dan Williams:
       "1) Fixes for a handful of smatch reports (Thanks Dan C.!) and minor
           bug fixes (patches 1-6)
      
        2) Correctness fixes to the BLK-mode nvdimm driver (patches 7-10).
      
           Granted these are slightly large for a -rc update.  They have been
           out for review in one form or another since the end of May and were
           deferred from the merge window while we settled on the "PMEM API"
           for the PMEM-mode nvdimm driver (ie memremap_pmem, memcpy_to_pmem,
           and wmb_pmem).
      
           Now that those apis are merged we implement them in the BLK driver
           to guarantee that mmio aperture moves stay ordered with respect to
           incoming read/write requests, and that writes are flushed through
           those mmio-windows and platform-buffers to be persistent on media.
      
        These pass the sub-system unit tests with the updates to
        tools/testing/nvdimm, and have received a successful build-report from
        the kbuild robot (468 configs).
      
        With acks from Rafael for the touches to drivers/acpi/"
