AFIAK, the way you are using USE_INIT is totally different from what
Greg is doing on PPC. I am not an expert on this issue but I believe
the only common thing in these two is the same macro name. Greg, can
you have some comment on this?
Auto.c and cache_as_ram_auto.c is very different
1. cache_as_ram_auto include failover.c
Why do you do that? Why don't you have cache_as_ram_failover.c too?
2. later cache_as_ram_auto will have struct sys_info
sysinfox, and it
will include every info include dimm.....and we don't need to keep read
smbus and pci conf space for....
Any reason it has to be in cache_as_ram_auto only?

Is there any reason we need two different ways to do it? If both of them
are as good, can we drop one and support just the other?
BTW, after reading your patch, I found there is very little difference
between auto.c and cache_as_ram_auto.c. Most of the differences are in
the included files, can we merge auto.c and cache_as_ram_auto.c?
