I can reproduce this locally with an allmodconfig build. The offset
parameter to make_nop_arm64 is nuts:

  Program received signal SIGSEGV, Segmentation fault.
  make_nop_arm64 (map=0x7ffff7fef000, offset=2600547309829750784) at scripts/recordmcount.c:170
  170		if (*ptr != 0x94000000)

Both shdr->sh_offset (0x17000000000000) and relp->r_offset (0x2400000000000000)
look dodgy in the caller.

Li, can you take a look please?
