+
+ Drop PS2 architecture support.
+
+ * i386/i386/fpu.c (fpintr): Remove PS2 from #if.
+ * 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.
+ * i386/i386/locore.S (RET_OFFSET): Remove PS2 stack layout.
+ * i386/i386/pic.c (picinit): Remove #ifdef PS2.
+ * i386/i386/pic.h: Remove PS2 from #if.
+ * i386/i386/pit.c (clock_int_handler): Remove extern declaration.
+ (clock_request_block, clock_flags, cqbuf): Remove variables.
+ (clkstart): Remove call to abios_clock_start function.
+ (abios_clock_start, ackrtclock): Remove function.
+ * i386/i386/pit.h: Remove PS2 from #if.
+
2006-10-26 Thomas Schwinge <tschwinge@gnu.org>
* Makefile.in: Regenerate.
