Subject: [PATCH v7 01/11] arm: perf: Remove inlines from arm_pmuv3.c
Date:   Mon, 11 Dec 2023 16:13:13 +0000
Message-Id: <20231211161331.1277825-2-james.clark@arm.com>
In-Reply-To: <20231211161331.1277825-1-james.clark@arm.com>
References: <20231211161331.1277825-1-james.clark@arm.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

These are all static and in one compilation unit so the inline has no
effect on the binary. Except if FTRACE is enabled, then 3 functions
which were already not inlined now get the nops added which allows them
to be traced.
