Commit some helper scripts

These only work on my workstation in the lab, but I find them useful and
want them versioned, so I'm committing them for now.  They do a cross
compile build of the kernel (xcc.sh) and install modules into a
sub-directory of the tree (ins_mods.sh).
Import Linux 3.8.8 in branch linux-newer

Let's try this one.
Update xccmake.sh with new ARCH options and specify CFLAGS

ARCH is now just sparc, not sparc64 and add -mcpu=niagara to CFLAGS
because why not?
Update branch linux-newer to Linux v3.9

3.8.8 had some problems, let's see if 3.9 has fixes for them! :)
Add support for forward ported patches from the OpenSPARC T1 tree

Applied by hand with slight changes.  Also made the things configurable.
Import & forward port sunhv_disk into Linux 3.9 tree.

This driver originally came from the OpenSPARC T1 tree, where it lives @
design/sys/edk/os/Ubuntu/7.10-Gutsy/src/drivers/sunhv_disk

This commit imports that driver into my Linux tree under drivers/block
and adds a config option for it.

Needed to update for new interfaces over the last 5 years.  I'm not sure
I have it right because I don't know the block interface almost at all,
so I just fixed whatever the compiler noticed was wrong.  It now
compiles, boots and even seems to work.

Good enough for now.
