From ebdf44a189984d6f72db6427194d4f5a6b07dc17 Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie@kernel.org> Date: Tue, 18 Feb 2020 19:58:34 +0000 Subject: [PATCH] arm64: head: Annotate stext and preserve_boot_args as code 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. Neither stext nor preserve_boot_args is called with the usual AAPCS calling conventions and they should therefore be annotated as code.
