In this case, I have to agree with PeterZ that this just looks odd:

-       if (get_user(ra, (unsigned long *)(cfa + frame->ra_off)))
+       if (UNWIND_GET_USER_LONG(ra, cfa + frame->ra_off, state))

why is UNWIND_GET_USER_LONG() so loud when it just replaces "get_user()"?

Note that "get_user()" itself is a macro, and is lower-case, even
though you couldn't actually do it as a function (because it changes
its first argument in place).

OK, I'll make it lower case.

Thanks!
