The patch titled
x86_64 setup.c: print cmp related boottime information
has been added to the -mm tree. Its filename is

See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: x86_64 setup.c: print cmp related boottime information
From: Rohit Seth <rohitseth@xxxxxxxxxx>
Get phys_proc_id and cpu_core_id information to be printed at boot time for
AMD processors. Also match the Node related boot time information that gets
printed for Intel and AMD processors for NUMA configurations.
