arm64: vdso32: Convert to modern assembler annotations
PATCH 1/1 arm64: vdso32: Convert to modern assembler annotations
In an effort to clarify and simplify the annotation of assembly functions new macros have been introduced. These replace ENTRY and ENDPROC with two different annotations for normal functions and those with unusual calling conventions. Use these for the compat VDSO, allowing us to drop the custom ARM_ENTRY() and ARM_ENDPROC() macros.
