Subject: [PATCH 12/18] arm64: kernel: Convert to modern annotations for assembly functions
Date: Tue, 18 Feb 2020 19:58:36 +0000	[thread overview]
Message-ID: <20200218195842.34156-13-broonie@kernel.org> (raw)
In-Reply-To: <20200218195842.34156-1-broonie@kernel.org>

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 core kernel code to
the new macros.
