[PATCH] x86: fix PDA variables to work during boot
The current PDA code, which went in in post 2.6.19 has a flaw in that it doesn't correctly cycle the GDT and %GS segment through the boot PDA, the CPU PDA and finally the per-cpu PDA. The bug generally doesn't show up if the boot CPU id is zero, but everything falls apart for a non zero boot CPU id. The basically kills voyager which is perfectly capable of doing non zero CPU id boots, so voyager currently won't boot without this. The fix is to be careful and actually do the GDT setups correctly.
