In that specific case, they are not executed, they are after a jump:

82e7: __switch_to_asm+0x27 <alternative.82e7>
= DEFAULT
82e7: __switch_to_asm+0x27 | jmp 0x8312 <__switch_to_asm+0x52>
82e9: __switch_to_asm+0x29 | NOP41

nop41 is a bit naf since x86 can only have 15 byte instructions :-)

Yes, "nop1 x41" would be better for this specific case. But I think
I will just drop it for now as Josh suggested.
