Subject: [PATCH v10 1/7] cpufreq: acpi: move MSR_K7_HWCR_CPB_DIS_BIT into msr-index.h
Date: Wed, 8 May 2024 15:21:06 +0800	[thread overview]
Message-ID: <5b37025fd0ce8f72ae4667bffd85dfdfb21380c5.1715152592.git.perry.yuan@amd.com> (raw)
In-Reply-To: <cover.1715152592.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.
