Unlike other alphas, marvel doesn't have real PC-style CMOS clock hardware
- RTC accesses are emulated via PAL calls.  Unfortunately, for unknown
reason these calls work only on CPU #0.  So current implementation for
arbitrary CPU makes CMOS_READ/WRITE to be executed on CPU #0 via IPI.
However, for obvious reason this doesn't work with standard
get/set_rtc_time() functions, where a bunch of CMOS accesses is done with
disabled interrupts.

Solved by making the IPI calls for entire get/set_rtc_time() functions,
not for individual CMOS accesses.  Which is also a lot more effective
performance-wise.

The patch is largely based on the code from Jay Estabrook.
My changes:
- tweak asm-generic/rtc.h by adding a couple of #defines to
  avoid a massive code duplication in arch/alpha/include/asm/rtc.h;
- sys_marvel.c: fix get/set_rtc_time() return values (Jay's FIXMEs).

NOTE: this fixes *only* LIB_RTC drivers.  Legacy (CONFIG_RTC) driver
wont't work on marvel.  Actually I think that we should just disable
CONFIG_RTC on alpha (maybe in 2.6.30?), like most other arches - AFAIK,
all modern distributions use LIB_RTC anyway.

This fixes some of the alpha-specific build problems, except a) modpost
warning about COMMON symbol "saved_config" and b) nasty final link
failure with gcc-4.x, -Os and scsi-disk driver configured built-in
(due to jump table in .rodata referencing discarded .exit.text).

- build failure with gcc-4.2.x: fix up casts in cia_io* routines to avoid
  warnings ('discards qualifiers from pointer target type'), which are
  failures, thanks to -Werror;
- modpost warnings: add missing __init qualifier for titan and marvel;
  for non-generic build, move machine vectors from .data to .data.init.refok
  section;
- unbreak CPU-specific optimization: rearrange cpuflags-y assignments
  so that extended -mcpu value (ev56, pca56, ev67) overrides basic
  one (ev5, ev6) and not vice versa.

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!
