Given the alignment, i'm going to assume i'm looking at the right thing:
0000000000000820 <__kvm_hyp_reset>:
820: d51c2000 msr ttbr0_el2, x0
824: d5033fdf isb
828: d50c871f tlbi alle2
82c: d5033f9f dsb sy
830: 10000060 adr x0, 83c <__kvm_hyp_reset+0x1c>
834: b3403c01 bfxil x1, x0, #0, #16
838: d61f0020 br x1
83c: d53c1000 mrs x0, sctlr_el2
but it seems fairly implausible to be trapping on ADR x0, 1f...
