Subject: [PATCH 09/18] arch: parisc: Remove CONFIG_OPROFILE support
Date: Thu, 14 Jan 2021 17:05:22 +0530 [thread overview]
Message-ID: <1b3e210d98d419eba4d0d648a3a181fe2190dc67.1610622251.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1610622251.git.viresh.kumar@linaro.org>
The "oprofile" user-space tools don't use the kernel OPROFILE support
any more, and haven't in a long time. User-space has been converted to
the perf interfaces.
Remove the old oprofile's architecture specific support.
