Subject: [RESEND PATCH v3 07/11] ARM: mark setup_machine_tags() stub as __init __noreturn
Date:   Tue, 23 Apr 2019 12:49:55 +0900
Message-Id: <20190423034959.13525-8-yamada.masahiro@socionext.com>
In-Reply-To: <20190423034959.13525-1-yamada.masahiro@socionext.com>

Precedence: bulk

This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place. We need to eliminate potential issues beforehand.

If it is enabled for arm, Clang build results in the following modpost
warning:

WARNING: vmlinux.o(.text+0x1124): Section mismatch in reference from the function setup_machine_tags() to the function .init.text:early_print()
The function setup_machine_tags() references
the function __init early_print().
This is often because setup_machine_tags lacks a __init
annotation or the annotation of early_print is wrong.
