that is also more efficient code by 6 bytes:

before:

ffffffff81020856:	ff c3                	inc    %ebx
ffffffff81020858:	48 05 f0 00 00 00    	add    $0xf0,%rax
ffffffff8102085e:	8b 00                	mov    (%rax),%eax
ffffffff81020860:	8b 15 2a 79 85 00    	mov    0x85792a(%rip),%edx        # ffffffff81878190 <hpet_t1_cmp>
ffffffff81020866:	89 c0                	mov    %eax,%eax
ffffffff81020868:	48 29 d0             	sub    %rdx,%rax
ffffffff8102086b:	48 85 c0             	test   %rax,%rax
ffffffff8102086e:	7f bf                	jg     ffffffff8102082f <hpet_rtc_interrupt+0x68>
ffffffff81020870:	85 db                	test   %ebx,%ebx

after:

ffffffff81020856:	ff c3                	inc    %ebx
ffffffff81020858:	48 05 f0 00 00 00    	add    $0xf0,%rax

ffffffff81020866:	85 c0                	test   %eax,%eax
