The duplication between pmd and pud collapse is a bit annoying, but so be it.

All these look good on a first reading, let me go build and test the various options.
I've tested:
GCC: ibt=off ibt=on LLVM: ibt-off,cfi=off ibt=off,cfi=kcfi ibt=on,cfi=off ibt=on,cfi=kcfi ibt=on,cfi=fineibt
And all of them were able to load a module, so yay!
My plan is to merge these patches into tip/x86/mm once we have -rc1.
