Subject: [PATCH v3 1/5] perf: cs-etm: Don't duplicate FIELD_GET()
Date:   Tue, 11 Jul 2023 11:02:11 +0100
Message-Id: <20230711100218.1651995-2-james.clark@arm.com>

Precedence: bulk

linux/bitfield.h can be included as long as linux/kernel.h is included
first, so change the order of the includes and drop the duplicate macro.
