e6cb602231 Moved macros for duplicate SSE/SSE2 functions from fetchdecode.h to 
cpu.h, and defined function prototypes for the case where bochs
  is compiled with a new #define (called StandAloneDecoder) is set.
  This allows for the decoder to be tested separately from bochs.
 2005-03-23 01:45:16 +00:00
Kevin Lawton
4e03c4448c Added some comment tags so that a script can pull out relevant parts 
of the decoder to test it in standalone mode.  A few lines in cpu.h
  were re-arranged to make this easy, but no real lines of code were
  changed or generated.
Changed a few PANICs to INFOs after testing corresponding cases.

the patch release notes by Zwane:

o Define symbols for constants like
o APIC arbitration
o Processor priority
o Various interrupt delivery fixes
o Focus processor checking
o ExtINT delivery

I need to release this now so that i don't fall too far behind CVS, when
it was part of the bochs-smp patch it could boot 2.4.18 4way. Apologies
for the whitespace changes.


Also remove patch.apic-ppr-zwane patch because it already included in
patch.apic-zwane.

I hope it will help to boot x86-64 or cmp systems required missed APIC
features !
