X-BeenThere: xen-devel@lists.xen.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Errors-To: xen-devel-bounces@lists.xen.org Sender: "Xen-devel" X-Virus-Scanned: ClamAV using ClamSMTP This patch moves 'cpuid_count_leaf' from cpuid.c to processor.h to make it available to external codes. Signed-off-by: Yi Sun Acked-by: Jan Beulich --- v9: - create this patch alone to move 'cpuid_count_leaf'. (suggested by Wei Liu) v6: - use 'struct cpuid_leaf' in psr.c. So we have to access 'cpuid_count_leaf' which has to be moved to processor.h.
