So far I have identified:

1) smp_locks
2) .alt_instructions - although from writing a script to parse the
alt_instr structures, it seems these may not affect .text, any
clarification on this would be greatly appreciated.
3) dynamic ftracing (related to mcount)

4)
I also see where the paravirt instructions (PVOP_CALL4) seems to
compile as absolute call instructions, but then become relative calls
at runtime.

maybe also kprobe and dynamic printk
