This fixes a "start_kernel(): bug: interrupts were enabled early".

rtc_cmos now takes care of initializing the ISA RTC and reading the
current time and date from it; there's no need to repeat that here,
thereby causing interrupts to be enabled too early.

This does not seem to be a recent breakage.

The ARCH_CO285 support is old - kernel 2.2.0 contains first traces of
it, an it seems to have been pretty complete in later 2.2 kernels.

Since it seems to be completely dead code now this patch therefore
removes it.

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!
