Subject: [PATCH 11/19] arm64: Group start_thread() functions together
Date: Fri, 18 Sep 2020 17:47:21 +0100	[thread overview]
Message-ID: <20200918164729.31994-12-will@kernel.org> (raw)
In-Reply-To: <20200918164729.31994-1-will@kernel.org>

The is_ttbrX_addr() functions have somehow ended up in the middle of
the start_thread() functions, so move them out of the way to keep the
code readable.
