Subject: [PATCH -next v6 02/10] arm64: asm-extable: move data fields
Date:   Tue, 21 Jun 2022 07:26:30 +0000
Message-ID: <20220621072638.1273594-3-tongtiangen@huawei.com>
In-Reply-To: <20220621072638.1273594-1-tongtiangen@huawei.com>

In subsequent patches we'll need to fill in extable data fields in
regular assembly files. In preparation for this, move the definitions of
the extable data fields earlier in asm-extable.h so that they are
defined for both assembly and C files.

There should be no functional change as a result of this patch.
