Konstantin Belousov 8f4a1f3a83 Bring back the save/restore of the %ds, %es, %fs and %gs registers for ... the 32bit images on amd64. Change the semantic of the PCB_32BIT pcb flag to request the context switch code to operate on the segment registers. Its previous meaning of saving or restoring the %gs base offset is assigned to the new PCB_GS32BIT flag. FreeBSD 32bit image activator sets the PCB_32BIT flag, while Linux 32bit emulation sets PCB_32BIT | PCB_GS32BIT. Reviewed by: peter MFC after: 2 weeks		2008-07-30 11:30:55 +00:00
