From: Mark Brown <[email protected]> commit 3ac0f4526dfb80625f5c2365bccd85be68db93ef upstream.
In an effort to clarify and simplify the annotation of assembly functions in the kernel new macros have been introduced. These replace ENTRY and ENDPROC and also add a new annotation for static functions which previously had no ENTRY equivalent. Update the annotations in the library code to the new macros.
