EIP > CS.limit should not be a problem
...
Manual says that GP(0) shouldd be generated in this case ALWAYS
Fixed instructions PANIC messages to ERROR for this case
And ... do not leave PANIC messages w/o taking care that user could push CONTINUE button and program should know to continue after the PANIC code line. Mainly in rerurn instructions were several problems ...

Merge and commit patch.apic-zwane from CVS patches directory.
...
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 !
