* i386/i386/gdt.c (abios_int_return, abios_th_return, intstack): Remove
extern declaration.
* i386/i386/gdt.h (ABIOS_INT_RET, ABIOS_TH_RET, ABIOS_INT_SS,
ABIOS_TH_SS, ABIOS_FIRST_AVAIL_SEL): Remove macros.
(GDTSZ): Remove PS2 case.
* i386/i386/hardclock.c: Don't include `i386/pic.h' and `i386/pio.h'.
(hardclock): Remove PS2 prototype and code.
