[PATCH: NEW ARCHITECTURE FOR 2.5.2] support for NCR voyager

[James Bottomley]

This is basically a layout change from the previous plus fixes for the new 
scheduler.  It's at

http://www.hansenpartnership.com/voyager/files/voyager-2.5.2.diff (150k)

I've tried to remove some of the voyager specific pieces from the i386 files 
by re-arranging the code.  The most significant change is to create a 
smp_intr_init() function and move it out of i8259.c

I've also altered process.c to allow overrides of the code for performing 
machine power off and restart and removed the actual code into voyager.c.

I've also addressed Dave Jones issues with the nesting in setup.c by creating 
a new machine_specific_memory_stup() function.  However, I can't move the 
voyager memory setup routines out of here unless I export some of the 
currently static interfaces which I'm loth to do.

I haven't included the patch to make the new scheduler work with an 
architecture that uses physical cpu id in p->cpu but I have sent that off 
separately to Ingo.
