struct pt_regs is hard to read because the member or section related
comments are not aligned with the members.
The 'cs' and 'ss' members of pt_regs are type of 'unsigned long' while
in reality they are only 16-bit wide. This works so far as the
remaining space is unused, but FRED will use the remaining bits for
other purposes.
To prepare for FRED:
- Cleanup the formatting
- Convert 'cs' and 'ss' to u16 and embed them into an union
with a u64
- Fixup the related printk() format strings
