Same thing in 17ea:
 0x00000001285942c0:  adrp  x8, 0x00000001280ed000   ;  {no_reloc}
 0x00000001285942c4:  add   x8, x8, #0x880
 0x00000001285942c8:  blr   x8
 0x00000001285942cc:  dcps1  #0xdeae
 0x00000001285942d0:  .inst  0x064e7d23 ; undefined
 0x00000001285942d4:  .inst  0x00000001 ; undefined

So i guess it's just register saving in 11, for exceptional situation.
