x86/asm changes for v6.8:
- Replace magic numbers in GDT descriptor definitions & handling:
- Introduce symbolic names via macros for descriptor types/fields/flags,
and then use these symbolic names.
- Clean up definitions a bit, such as GDT_ENTRY_INIT()
- Fix/clean up details that became visibly inconsistent after the
symbol-based code was introduced:
- Unify accessed flag handling
- Set the D/B size flag consistently & according to the HW specification
