Extract out the code patching code from kprobes so that it can be used
from the jump label code. Additionally, the separated code:
- Uses the IS_ENABLED() macros instead of the #ifdefs for THUMB2
support
- Unifies the two separate functions in kprobes, providing one function
that uses stop_machine() internally, and one that can be called from
stop_machine() directly
- Patches the text on all CPUs only on processors requiring software
broadcasting of cache operations
