      Pull x86 fix from Borislav Petkov:
       "A single fix for objtool to generate proper unwind info for newer
        toolchains which do not generate section symbols anymore. And a
        cleanup ontop.
      
        This was originally going to go during the next merge window but
        people can already trigger a build error with binutils-2.36 which
        doesn't emit section symbols - something which objtool relies on - so
        let's expedite it"

      Pull timer fix from Thomas Gleixner:
       "A fix for handling advertised, but non-existent 146818 RTCs correctly.
      
        With the recent UIP handling changes the time readout of non-existent
        RTCs hangs forever as the read returns always 0xFF which means the UIP
        bit is set.
      
        Sanity check the RTC before registering by checking the RTC_VALID
        register for correctness"

      leds: rt8515: Add Richtek RT8515 LED driver · e1c6edcb
      Linus Walleij authored
      This adds a driver for the Richtek RT8515 dual channel
      torch/flash white LED driver.
      
      This LED driver is found in some mobile phones from
      Samsung such as the GT-S7710 and GT-I8190.
      
      A V4L interface is added.
      
      We do not have a proper datasheet for the RT8515 but
      it turns out that RT9387A has a public datasheet and
      is essentially the same chip. We designed the driver
      in accordance with this datasheet. The day someone
      needs to drive a RT9387A this driver can probably
      easily be augmented to handle that chip too.
      
      Sakari Ailus, Pavel Machek and Andy Shevchenko helped
      significantly in getting this driver right.

      This lockdep splat is reported after:
      commit e9181886 ("locking: More accurate annotations for read_lock()")
      
      To clarify:
       - read-locks are recursive only in interrupt context (when
         in_interrupt() returns true)
       - after acquiring host->lock in CPU1, another cpu (i.e. CPU2) may call
         write_lock(&trig->leddev_list_lock) that would be blocked by CPU0
         that holds trig->leddev_list_lock in read-mode
       - when CPU1 (ata_ac_complete()) tries to read-lock
         trig->leddev_list_lock, it would be blocked by the write-lock waiter
         on CPU2 (because we are not in interrupt context, so the read-lock is
         not recursive)
       - at this point if an interrupt happens on CPU0 and
         ata_bmdma_interrupt() is executed it will try to acquire host->lock,
         that is held by CPU1, that is currently blocked by CPU2, so:
      
         * CPU0 blocked by CPU1
         * CPU1 blocked by CPU2
         * CPU2 blocked by CPU0
      
           *** DEADLOCK ***
      
      The deadlock scenario is better represented by the following schema
      (thanks to Boqun Feng <boqun.feng@gmail.com> for the schema and the
      detailed explanation of the deadlock condition):
      
       CPU 0:                          CPU 1:                        CPU 2:
       -----                           -----                         -----
       led_trigger_event():
         read_lock(&trig->leddev_list_lock);
       				<workqueue>
       				ata_hsm_qc_complete():
       				  spin_lock_irqsave(&host->lock);
       								write_lock(&trig->leddev_list_lock);
       				  ata_port_freeze():
       				    ata_do_link_abort():
       				      ata_qc_complete():
       					ledtrig_disk_activity():
       					  led_trigger_blink_oneshot():
       					    read_lock(&trig->leddev_list_lock);
       					    // ^ not in in_interrupt() context, so could get blocked by CPU 2
       <interrupt>
         ata_bmdma_interrupt():
           spin_lock_irqsave(&host->lock);
      
      Fix by using read_lock_irqsave/irqrestore() in led_trigger_event(), so
      that no interrupt can happen in between, preventing the deadlock
      condition.
      
      Apply the same change to led_trigger_blink_setup() as well, since the
      same deadlock scenario can also happen in power_supply_update_bat_leds()
      -> led_trigger_blink() -> led_trigger_blink_setup() (workqueue context),
      and potentially prevent other similar usages.

      dt-bindings: Cleanup standard unit properties · 32ada6b0
      Rob Herring authored
      Properties with standard unit suffixes already have a type and don't need
      type definitions. They also default to a single entry, so 'maxItems: 1'
      can be dropped.
      
      adi,ad5758 is an oddball which defined an enum of arrays. While a valid
      schema, it is simpler as a whole to only define scalar constraints.

      soc: litex: Properly depend on HAS_IOMEM · 1bea2a93
      David Gow authored
      The LiteX SOC controller driver makes use of IOMEM functions like
      devm_platform_ioremap_resource(), which are only available if
      CONFIG_HAS_IOMEM is defined.
      
      This causes the driver to be enable under make ARCH=um allyesconfig,
      even though it won't build.
      
      By adding a dependency on HAS_IOMEM, the driver will not be enabled on
      architectures which don't support it.

      tty: avoid using vfs_iocb_iter_write() for redirected console writes · a9cbbb80
      Linus Torvalds authored
      It turns out that the vfs_iocb_iter_{read,write}() functions are
      entirely broken, and don't actually use the passed-in file pointer for
      IO - only for the preparatory work (permission checking and for the
      write_iter function lookup).
      
      That worked fine for overlayfs, which always builds the new iocb with
      the same file pointer that it passes in, but in the general case it ends
      up doing nonsensical things (and could cause an iterator call that
      doesn't even match the passed-in file pointer).
      
      This subtly broke the tty conversion to write_iter in commit
      9bb48c82 ("tty: implement write_iter"), because the console
      redirection didn't actually end up redirecting anything, since the
      passed-in file pointer was basically ignored, and the actual write was
      done with the original non-redirected console tty after all.
      
      The main visible effect of this is that the console messages were no
      longer logged to /var/log/boot.log during graphical boot.
      
      Fix the issue by simply not using the vfs write "helper" function at
      all, and just redirecting the write entirely internally to the tty
      layer.  Do the target writability permission checks when actually
      registering the target tty with TIOCCONS instead of at write time.
      
      Fixes: 9bb48c82 ("tty: implement write_iter")

      drm/nouveau/kms/gk104-gp1xx: Fix > 64x64 cursors · ba839b75
      Lyude Paul authored
      While we do handle the additional cursor sizes introduced in NVE4, it looks
      like we accidentally broke this when converting over to use Nvidia's
      display headers. Since we now use NVVAL in dispnv50/head907d.c in order to
      format the value for the cursor layout and NVD9 only had one byte reserved
      vs. the 2 bytes reserved in later generations, we end up accidentally
      stripping the second bit in the cursor layout format parameter - causing us
      to set the wrong cursor size.
      
      This fixes that by adding our own curs_set hook for 917d which uses the
      NV917D headers.
