Paul Mundt 19f9a34f87 sh: Initial vsyscall page support.
This implements initial support for the vsyscall page on SH.
At the moment we leave it configurable due to having nommu
to support from the same code base. We hook it up for the
signal trampoline return at present, with more to be added
later, once uClibc catches up.

Paul Mundt e5723e0eeb sh: Add support for SH7706/SH7710/SH7343 CPUs.
This adds support for the aforementioned CPU subtypes, and cleans
up some build issues encountered as a result.

Paul Mundt e7f93a355c sh: Make PAGE_OFFSET configurable.
nommu needs to be able to shift PAGE_OFFSET, so we switch it to a
non-user-visible CONFIG_PAGE_OFFSET and use that in the few places
where it matters.

Paul Mundt a328ff9a7e sh: SE73180 updates for IRQ changes.
SE73180 can use the generic support, we just need to
wire up the IRQ demuxing.

Paul Mundt cad8244840 [PATCH] sh: Move CPU subtype configuration to its own Kconfig
Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat.

Given that, this moves all of that in to its own arch/sh/mm/Kconfig.  Things
like cache configuration are also moved to this new location.

This also adds support for strict CPU tuning on newer cores, which requires
the addition of as-option.
