Change Details

- Set PCB_FULL_IRET in pcb_flags when adjusting fsbase or gsbase. linux32 was setting PCB_32BIT which should be a no-op (exec sets it). - Remove write-only variables to construct unused segment descriptors for linux32.

- Use update_pcb_bases() when updating FS or GS base addresses to permit use of FSBASE and GSBASE in Linux processes. This also sets PCB_FULL_IRET. linux32 was setting PCB_32BIT which should be a no-op (exec sets it). - Remove write-only variables to construct unused segment descriptors for linux32.
