This version won't eat your memory and swap when building the entire
kernel.  Apologies to Andy who discovered this over the weekend.

Tested full build and boot w/o problem.  The vmlinux sections, relocs,
size, etc. all appear to be the same before and after this set.
External tooling (kpatch-build) is happy, too.

v3:
- fix bug introduced in arch_decode_instruction() [andy]

v2:
- drop the sec->len update from the first patch [josh]
- rip out sec->len as suggested [josh]


Joe Lawrence (2):
  objtool: make .altinstructions section entry size consistent
  objtool: remove redundant len value from struct section
