	Ok, my objdump didn't do a good job.  With gdb I get:

0xc04040bd <xen_set_pte_at+185>:	mov    %edi,(%eax)
0xc01687f0:	Cannot access memory at address 0xc01687f0
0xc0417ab6 <__set_fixmap+326>:	pop    %ecx
0xc040288f <xen_alloc_ptpage+41>:	lock btsl $0x8,(%eax)
0xc040299a <xen_load_idt+74>:	lock incb 0xc0766148
0xc0403270 <xen_set_pte_atomic+26>:	lock cmpxchg8b (%edi)
