Frank Rowand 045470f9f7 preempt-rt: Convert arm boot_lock to raw
The arm boot_lock is used by the secondary processor startup code.  The locking
task is the idle thread, which has idle->sched_class == &idle_sched_class.
idle_sched_class->enqueue_task == NULL, so if the idle task blocks on the
lock, the attempt to wake it when the lock becomes available will fail:

try_to_wake_up()
   ...
      activate_task()
         enqueue_task()
            p->sched_class->enqueue_task(rq, p, flags)

Fix by converting boot_lock to a raw spin lock.

Linus Torvalds 9b6d351a75 ARM: SoC DT updates for 3.14
DT and DT-conversion-related changes for various ARM platforms. Most
 of these are to enable various devices on various boards, etc, and not
 necessarily worth enumerating.
 
 New boards and systems continue to come in as new devicetree files that
 don't require corresponding C changes any more, which is indicating that
 the system is starting to work fairly well.
 
 A few things worth pointing out:
 
 * ST Ericsson ux500 platforms have made the major push to move over to fully
   support the platform with DT.
 * Renesas platforms continue their conversion over from legacy platform devices
   to DT-based for hardware description.

Linus Torvalds f2c73464d7 ARM: SoC cleanups for 3.14
This is the branch where we usually queue up cleanup efforts, moving
 drivers out of the architecture directory, header file restructuring,
 etc. Sometimes they tangle with new development so it's hard to keep it
 strictly to cleanups.
 
 Some of the things included in this branch are:
 
 * Atmel SAMA5 conversion to common clock
 * Reset framework conversion for tegra platforms
  - Some of this depends on tegra clock driver reworks that are shared with Mike
    Turquette's clk tree.
 * Tegra DMA refactoring, which are shared branches with the DMA tree.
 * Removal of some header files on exynos to prepare for multiplatform
