3d5ae6b69e [SPARC64]: Fix sparse warnings in arch/sparc64/kernel/{cpu,setup}.c
We create a local header file entry.h, under arch/sparc64/kernel/,
that we can use to declare routines either defined in assembler
or only invoked from assembler.  As well as other data objects
which are private to the inner sparc64 kernel arch code.

6c70b6fc7b [SPARC64]: Do not assume sun4v chips have load-twin/store-init support.
Check the cpu type in the OBP device tree before committing to
using the optimized Niagara memcpy and memset implementation.

If we don't recognize the cpu type, use a completely generic
version.

d82ace7dc4 [SPARC64]: Detect sun4v early in boot process.
We look for "SUNW,sun4v" in the 'compatible' property
of the root OBP device tree node.

Protect every %ver register access, to make sure it is
not touched on sun4v, as %ver is hyperprivileged there.

Lock kernel TLB entries using hypervisor calls instead of
calls into OBP.

84c1a13a30 [SPARC64]: Use ARRAY_SIZE macro
Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove a
duplicate of ARRAY_SIZE which is never used anyways.

d2212bc7db [SPARC64]: Add missing IDs for newer cpus.
Also, the us3_cpufreq driver can work on Ultra-IV and IV+.
They use the SAFARI bus register to control the clock divider
just like Ultra-III and III+ do.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
