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)
