Subject: [PATCH 05/10] x86/cpu: Move TSC CPUID leaf definition
Date: Fri, 13 Dec 2024 12:50:33 -0800 [thread overview]
Message-ID: <20241213205033.68799E53@davehans-spike.ostc.intel.com> (raw)
In-Reply-To: <20241213205026.25B1D283@davehans-spike.ostc.intel.com>
From: Dave Hansen <dave.hansen@linux.intel.com>
Prepare to use the TSC CPUID leaf definition more widely by moving
it to the common header.
