      Pull timer updates from Ingo Molnar:
       "The main changes in the timer code in this cycle were:
      
         - Clockevent updates:
      
            - timer-of framework cleanups. (Geert Uytterhoeven)
      
            - Use timer-of for the renesas-ostm and the device name to prevent
              name collision in case of multiple timers. (Geert Uytterhoeven)
      
            - Check if there is an error after calling of_clk_get in asm9260
              (Chuhong Yuan)
      
         - ABI fix: Zero out high order bits of nanoseconds on compat
           syscalls. This got broken a year ago, with apparently no side
           effects so far.
      
           Since the kernel would use random data otherwise I don't think we'd
           have other options but to fix the bug, even if there was a side
           effect to applications (Dmitry Safonov)
      
         - Optimize ns_to_timespec64() on 32-bit systems: move away from
           div_s64_rem() which can be slow, to div_u64_rem() which is faster
           (Arnd Bergmann)
      
         - Annotate KCSAN-reported false positive data races in
           hrtimer_is_queued() users by moving timer->state handling over to
           the READ_ONCE()/WRITE_ONCE() APIs. This documents these accesses
           (Eric Dumazet)
      
         - Misc cleanups and small fixes"
      
      [ I undid the "ABI fix" and updated the comments instead. The reason
        there were apparently no side effects is that the fix was a no-op.
      
        The updated comment is to say _why_ it was a no-op.    - Linus ]
      
      * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
        time: Zero the upper 32-bits in __kernel_timespec on 32-bit
        time: Rename tsk->real_start_time to ->start_boottime
        hrtimer: Remove the comment about not used HRTIMER_SOFTIRQ
        time: Fix spelling mistake in comment
        time: Optimize ns_to_timespec64()
        hrtimer: Annotate lockless access to timer->state
        clocksource/drivers/asm9260: Add a check for of_clk_get
        clocksource/drivers/renesas-ostm: Use unique device name instead of ostm

      Pull irq updates from Ingo Molnar:
       "Most of the IRQ subsystem changes in this cycle were irq-chip driver
        updates:
      
         - Qualcomm PDC wakeup interrupt support
      
         - Layerscape external IRQ support
      
         - Broadcom bcm7038 PM and wakeup support

         - GICv4 fixes
      
        There's also the series from Frederic Weisbecker that fixes memory
        ordering bugs for the irq-work logic, whose primary fix is to turn
        work->irq_work.flags into an atomic variable and then convert the
        complex (and buggy) atomic_cmpxchg() loop in irq_work_claim() into a
        much simpler atomic_fetch_or() call.

      Add a utility function dmi_memdev_handle() which returns the DMI
      handle associated with a given memory slot. This will allow kernel
      drivers to iterate over the memory slots.

      Pull XFS updates from Darrick Wong:
       "For this release, we changed quite a few things.
      
        Highlights:
      
         - Fixed some long tail latency problems in the block allocator
      
         - Removed some long deprecated (and for the past several years no-op)
           mount options and ioctls
      
         - Strengthened the extended attribute and directory verifiers
      
         - Audited and fixed all the places where we could return EFSCORRUPTED
           without logging anything
      
         - Refactored the old SGI space allocation ioctls to make the
           equivalent fallocate calls
      
         - Fixed a race between fallocate and directio
      
         - Fixed an integer overflow when files have more than a few
           billion(!) extents
      
         - Fixed a longstanding bug where quota accounting could be incorrect
           when performing unwritten extent conversion on a freshly mounted fs
      
         - Fixed various complaints in scrub about soft lockups and
           unresponsiveness to signals
      
         - De-vtable'd the directory handling code, which should make it
           faster
      
         - Converted to the new mount api, for better or for worse
      
         - Cleaned up some memory leaks
      
        and quite a lot of other smaller fixes and cleanups.
      
        A more detailed summary:
      
         - Fill out the build string
      
         - Prevent inode fork extent count overflows
      
         - Refactor the allocator to reduce long tail latency
      
         - Rework incore log locking a little to reduce spinning
      
         - Break up the xfs_iomap_begin functions into smaller more cohesive
           parts
      
         - Fix allocation alignment being dropped too early when the
           allocation request is for more blocks than an AG is large
      
         - Other small cleanups
      
         - Clean up file buftarg retrieval helpers
      
         - Hoist the resvsp and unresvsp ioctls to the vfs
      
         - Remove the undocumented biosize mount option, since it has never
           been mentioned as existing or supported on linux
      
         - Clean up some of the mount option printing and parsing
      
         - Enhance attr leaf verifier to check block structure
      
         - Check dirent and attr names for invalid characters before passing
           them to the vfs
      
         - Refactor open-coded bmbt walking
      
         - Fix a few places where we return EIO instead of EFSCORRUPTED after
           failing metadata sanity checks
      
         - Fix a synchronization problem between fallocate and aio dio
           corrupting the file length
      
         - Clean up various loose ends in the iomap and bmap code
      
         - Convert to the new mount api
      
         - Make sure we always log something when returning EFSCORRUPTED
      
         - Fix some problems where long running scrub loops could trigger soft
           lockup warnings and/or fail to exit due to fatal signals pending
      
         - Fix various Coverity complaints
      
         - Remove most of the function pointers from the directory code to
           reduce indirection penalties
      
         - Ensure that dquots are attached to the inode when performing
           unwritten extent conversion after io
      
         - Deuglify incore projid and crtime types
      
         - Fix another AGI/AGF locking order deadlock when renaming
      
         - Clean up some quota typedefs
      
         - Remove the FSSETDM ioctls which haven't done anything in 20 years
      
         - Fix some memory leaks when mounting the log fails
      
         - Fix an underflow when updating an xattr leaf freemap

         - Various kerneldoc script enhancements.
      
         - More RST conversions; those are slowing down as we run out of
           things to convert, but we're a ways from done still.
      
         - Dan's "maintainer profile entry" work landed at last. Now we just
           need to get maintainers to fill in the profiles...
      
         - A reworking of the parallel build setup to work better with a
           variety of systems (and to not take over huge systems entirely in
           particular).
      
         - The MAINTAINERS file is now converted to RST during the build.
           Hopefully nobody ever tries to print this thing, or they will need
           to load a lot of paper.
      
         - A script and documentation making it easy for maintainers to add
           Link: tags at commit time.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.5 kernel cycle
      
        Core changes:
      
         - Expose pull up/down flags for the GPIO character device to
           userspace.
      
           After clear input from the RaspberryPi and Beagle communities, it
           has been established that prototyping, industrial automation and
           make communities strongly need this feature, and as we want people
           to use the character device, we have implemented the simple pull
           up/down interface for GPIO lines.
      
           This means we can specify that a (chip-specific) pull up/down
           resistor can be enabled, but does not offer fine-grained control
           such as cases where the resistance of the same pull resistor can be
           controlled (yet).
      
         - Introduce devm_fwnode_gpiod_get_index() and start to phase out the
           old symbol devm_fwnode_get_index_gpiod_from_child().
      
         - A bit of documentation clean-up work.
      
         - Introduce a define for GPIO line directions and deploy it in all
           GPIO drivers in the drivers/gpio directory.
      
         - Add a special callback to populate pin ranges when cooperating with
           the pin control subsystem and registering ranges as part of adding
           a gpiolib driver and a gpio_irq_chip driver at the same time. This
           is also deployed in the Intel Merrifield driver.
      
        New drivers:
      
         - RDA Micro GPIO controller.
      
         - XGS-iproc GPIO driver.
      
        Driver improvements:
      
         - Wake event and debounce support on the Tegra 186 driver.
      
         - Finalize the Aspeed SGPIO driver.
      
         - MPC8xxx uses a normal IRQ handler rather than a chained handler"
