From 1e4729ed028d1e70508926a58363ee85243fdaaa Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 18 Feb 2020 19:58:32 +0000 Subject: [PATCH] arm64: ftrace: Modernise annotation of return_to_handler 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. return_to_handler does entertaining things with LR so doesn't follow the usual C conventions and should therefore be annotated as code rather than a function.
