Make the "defconfig" target valid for arch/h8300.  Currently
"make ARCH=h8300 defconfig" produces:

*** Can't find default configuration "arch/h8300/defconfig"!
../scripts/kconfig/Makefile:87: recipe for target 'defconfig' failed

By adding a value for KBUILD_DEFCONFIG, "make ARCH=h8300 defconfig"
successfully produces a kernel .config file:

*** Default configuration is based on 'edosk2674_defconfig'

This is useful for Kconfig editing/testing.

All 64bit archs use unsigned long for size_t and most 32bit
archs use 'unsigned int'. By default, this is what is assumed
by sparse.

However, on h8300 (a 32bit arch) size_t is unsigned long which
can led sparse to emit wrong warnings.

Fix this by passing to sparse the flag -msize-long, telling it
that size_t is unsigned long.

Commit 0fa1c579 ("of/fdt: use memblock_virt_alloc for early alloc")
inadvertently switched the DT unflattening allocations from memblock to
bootmem which doesn't work because the unflattening happens before
bootmem is initialized. Swapping the order of bootmem init and
unflattening could also fix this, but removing bootmem is desired. So
enable NO_BOOTMEM on h8300 like other architectures have done.

     actually delivered we know if the signal is being sent to a a group

     appear to be received after the fork completes"

Pull tracing updates from Steven Rostedt:

 - Restructure of lockdep and latency tracers

   This is the biggest change. Joel Fernandes restructured the hooks
   from irqs and preemption disabling and enabling. He got rid of a lot
   of the preprocessor #ifdef mess that they caused.

   He turned both lockdep and the latency tracers to use trace events
   inserted in the preempt/irqs disabling paths. But unfortunately,
   these started to cause issues in corner cases. Thus, parts of the
   code was reverted back to where lockdep and the latency tracers just
   get called directly (without using the trace events). But because the
   original change cleaned up the code very nicely we kept that, as well
   as the trace events for preempt and irqs disabling, but they are
   limited to not being called in NMIs.

 - Have trace events use SRCU for "rcu idle" calls. This was required
   for the preempt/irqs off trace events. But it also had to not allow
   them to be called in NMI context. Waiting till Paul makes an NMI safe
   SRCU API.

 - New notrace SRCU API to allow trace events to use SRCU.

 - Addition of mcount-nop option support

 - SPDX headers replacing GPL templates.

 - Various other fixes and clean ups.

Pull RTC updates from Alexandre Belloni:
 "It is now possible to add custom sysfs attributes while avoiding a
  possible race condition. Unused code has been removed resulting in a
  nice reduction of the code base. And more drivers have been switched
  to SPDX by their maintainers.

 Summary:

  Subsystem:
   - new helpers to add custom sysfs attributes
   - struct rtc_task removal along with rtc_irq_[un]register()
   - rtc_irq_set_state and rtc_irq_set_freq are not exported anymore

  Drivers:
   - armada38x: reset after rtc power loss
   - ds1307: now supports m41t11
   - isl1208: now supports isl1219 and tamper detection
   - pcf2127: internal SRAM support"
