Modified Files:
        src/sys/arch/amd64/amd64: amd64_trap.S locore.S
        src/sys/arch/amd64/include: frameasm.h
        src/sys/arch/x86/x86: cpu.c

Log Message:
Have the cpu clear PSL_D automatically when entering the kernel via a
syscall. Then, don't clear PSL_D and PSL_AC in the syscall entry point,
they are now both cleared by the cpu (faster). However they still need to
be manually cleared in the interrupt/trap entry points.
