test case
As seen in Fedora rawhide (4.9):
0x000003ffb1371ea4 <+100>: cmp w6, #0x1
0x000003ffb1371ea8 <+104>: adrp x0, 0x3ffb1385000
0x000003ffb1371eac <+108>: ldr x7, [x0,#352]
0x000003ffb1371eb0 <+112>: add x0, x0, #0x160
0x000003ffb1371eb4 <+116>: blr x7
0x000003ffb1371eb8 <+120>: mov w4, w5
0x000003ffb1371ebc <+124>: add x0, x3, x0
0x000003ffb1371ec0 <+128>: b.eq 0x3ffb1372088 <capng_update+584>
but I don't see anything preventing this on HEAD.
Patch to follow.
