Subject: [PATCH] x86/cpu: Move identify_cpu_without_cpuid() into main branch
Date: Tue, 21 May 2024 15:48:23 +0300 [thread overview]
Message-ID: <20240521124823.486372-1-nik.borisov@suse.com> (raw)
No point in duplicating if (!have_cpuid_p()) check. Simply move
identify_cpu_without_cpuid() into the else branch. No functional
changes.
