Usual cleanup.		  
117 6940 d 4 h jermar /SPARTAN/trunk/ Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.

Tiny changes here and there.		  
112 6948 d 0 h jermar /SPARTAN/trunk/ Define two placeholder functions for atomic_inc and atomic_dec on IA-64.

110 6949 d 5 h jermar /SPARTAN/trunk/ SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.

MIPS.
Move msim dprinter device to 0xB0000000.
