Compiling 2.6.21-rc5 with gcc-4.2.0 20070317 (prerelease)
for sparc64 fails as follows:

gcc gets unhappy when the MSTK_SET macro's u8 __val variable
is updated with &= ~0xff (MSTK_YEAR_MASK). Making the constant
unsigned fixes the problem.
[ I fixed up the sparc32 side as well -DaveM ]

void * __iomem foo is not a pointer to iomem - it's an iomem variable
containing void *. A pile of such guys in arch/sparc64/kernel/time.c,
drivers/sbus/char/rtc.c and include/asm-sparc64/mostek.h turned into
intended void __iomem *.

Provide support for drivers/char/rtc.c ioctls in the
Mostek rtc driver as well as the Sparc specific RTCGET
and RTCSET.
This allows userspace to be much less messy. Currently
util-linux and other spots jump through hoops trying
various ioctl variants until it hits the right one whatever
driver actually being used supports.
Eventually all of this should move over to the genrtc.c
driver, but not today...
While we are here, fix up the register types for sparse.
Thanks to Frans Pop for helping point out this issue.

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!
