Subject: [PATCH v9 1/7] cpufreq: acpi: move MSR_K7_HWCR_CPB_DIS_BIT into msr-index.h
Date: Mon, 6 May 2024 18:19:53 +0800 [thread overview]
Message-ID: <b7ac14ae34c470579d02d55cd57e017daaefb21e.1714989803.git.perry.yuan@amd.com> (raw)
In-Reply-To: <cover.1714989803.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.
