2020-09-10objtool: Make unwind hint definitions available to other architecturesJulien Thierry1-0/+88
Unwind hints are useful to provide objtool with information about stack states in non-standard functions/code. While the type of information being provided might be very arch specific, the mechanism to provide the information can be useful for other architectures. Move the relevant unwint hint definitions for all architectures to see.
