[Josh Poimboeuf]

v3:
- remove "size = 0" and add comments to create_fake_symbols()
- add patches 8 & 9

v2: https://lore.kernel.org/cover.1785939903.git.jpoimboe@xxxxxxxxxx
- rebased on tip/master (first 6 patches were merged)
- dropped original patches 7-8 (will post followup)
- added .klp.symid fix

v1: https://lore.kernel.org/cover.1785727106.git.jpoimboe@xxxxxxxxxx

This consolidates fixes for the klp-build issues reported by Joe over
the last several weeks, plus some more things I found while
testing/reviewing.
