Subject: [PATCH v13 1/9] cpufreq: acpi: move MSR_K7_HWCR_CPB_DIS_BIT into msr-index.h
Date: Sat, 22 Jun 2024 00:50:56 +0800 [thread overview]
Message-ID: <78b6c75e6cffddce3e950dd543af6ae9f8eeccc3.1718988436.git.perry.yuan@amd.com> (raw)
In-Reply-To: <cover.1718988436.git.perry.yuan@amd.com>
There are some other drivers also need to use the
MSR_K7_HWCR_CPB_DIS_BIT for CPB control bit, so it makes sense to move
the definition to a common header file to allow other driver to use it.
No intentional functional impact.
