Pull ARM updates from Russell King:
 "In this ARM merge, we remove more lines than we add.  Changes include:

   - Enable imprecise aborts early, so that bus errors aren't masked
     until later in the boot.  This has the side effect that boot
     loaders which provoke these aborts can cause the kernel to crash
     early in boot, so we install a handler to report this event around
     the site where these are enabled.

   - Remove the buggy but impossible to enable cmpxchg syscall code.

   - Add unwinding annotations to some assembly code.

   - Add support for atomic half-word exchange for ARMv6k+.

   - Reduce ioremap() alignment for SMP/LPAE cases where we don't need
     the large alignment.

   - Addition of an "optimal" 3G configuration for systems with 1G of
     RAM.

   - Increase vmalloc space by 128M.

   - Constify some SMP operations structures, which have never been
     writable.

   - Improve ARMs dma_mmap() support for mapping DMA coherent mappings
     into userspace.

   - Fix to the NMI backtrace code in the IPI case on ARM where the
     failing CPU gets stuck for 10s waiting for its own IPI to be
     delivered.

Use resource-managed function devm_led_classdev_register instead
of led_classdev_register to make the error-path simpler.

To be compatible with the change, goto is replaced with direct
return, unneeded label err_null is dropped and unnecessary variable
retval is removed. Also, remove redundant cobalt_qube_led_remove.

Pull regmap updates from Mark Brown:
 "Quite a few new features for regmap this time, mostly expanding things
  around the edges of the existing functionality to cover more devices
  rather than thinsg with wide applicability:

   - Support for offload of the update_bits() operation to hardware
     where devices implement bit level access.
   - Support for a few extra operations that need scratch buffers on
     fast_io devices where we can't sleep.
   - Expanded the feature set of regmap_irq to cope with some extra
     register layouts.
   - Cleanups to the debugfs code"

* tag 'regmap-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
  regmap: Allow installing custom reg_update_bits function
  regmap: debugfs: simplify regmap_reg_ranges_read_file() slightly
  regmap: debugfs: use memcpy instead of snprintf
  regmap: debugfs: use snprintf return value in regmap_reg_ranges_read_file()
  regmap: Add generic macro to define regmap_irq
  regmap: debugfs: Remove scratch buffer for register length calculation
  regmap: irq: add ack_invert flag for chips using cleared bits as ack
  regmap: irq: add support for chips who have separate unmask registers
  regmap: Allocate buffers with GFP_ATOMIC when fast_io == true
