dd2fdd264e sh64: provide a stub per_cpu_trap_init() definition.
This is needed to fix up the build at the moment. Gradually this will be
reworked to follow the 32-bit initialization path and deal with delayed
VBR initialization.

c77b29db74 sh: fix up CONFIG_KEXEC=n build.
The reserve_crashkernel() definition is in asm/kexec.h which is only
dragged in via linux/kexec.h if CONFIG_KEXEC is set. Just switch over to
asm/kexec.h unconditionally to fix up the build.

fa676ca394 sh: move sh clock-cpg.c contents to drivers/sh/clk-cpg.c
Move the CPG helpers to drivers/sh/clk-cpg.c V2.

This to allow SH-Mobile ARM to share the code with
SH. All functions except the legacy CPG stuff is moved.

8b5ee113e1 sh: move sh clock.c contents to drivers/sh/clk.
This patch is V2 of the SH clock framework move from
arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All
code except the following functions are moved:
clk_init(), clk_get() and clk_put().

The init function is still kept in clock.c since it
depends on the SH-specific machvec implementation.

The symbols clk_get() and clk_put() already exist in
the common ARM clkdev code, those symbols are left in
the SH tree to avoid duplicating them for SH-Mobile ARM.

This patch is V2 of the clock framework move from

21823259a7 sh: Ensure active regions have a backing PMB entry.
In the NUMA or memory hot-add case where system memory has been
partitioned up, we immediately run in to a situation where the existing
PMB entry doesn't cover the new range (primarily as a result of the entry
size being shrunk to match the node size early in the initialization). In
order to fix this up it's necessary to preload a PMB mapping for the new
range prior to activation in order to circumvent reset by MMU.

The minimum section size for the PMB is 16M, so just always error

4bc277ac9c sh: bootmem refactoring.
This reworks much of the bootmem setup and initialization code allowing
us to get rid of duplicate work between the NUMA and non-NUMA cases. The
end result is that we end up with a much more flexible interface for
supporting more complex topologies (fake NUMA, highmem, etc, etc.) which
is entirely LMB backed. This is an incremental step for more NUMA work as
well as gradually enabling migration off of bootmem entirely.
