Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Fri, 30 Nov 2012 15:18:16 -0800 x86/smpboot.c: Early update ucode on AP This updates ucode on AP. At this point, BSP should store some valid ucode patches in memory if it finds the ucode patches in initrd. AP searches the stored ucode and uploads the ucode.
