Merge branch 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 boot changes from Ingo Molnar:
"Two changes that prettify and compactify the SMP bootup output from:
smpboot: Booting Node 0, Processors #1 #2 #3 OK
smpboot: Booting Node 1, Processors #4 #5 #6 #7 OK
smpboot: Booting Node 2, Processors #8 #9 #10 #11 OK
smpboot: Booting Node 3, Processors #12 #13 #14 #15 OK
Brought up 16 CPUs
to something like:
x86: Booting SMP configuration:
.... node #0, CPUs: #1 #2 #3
.... node #1, CPUs: #4 #5 #6 #7
.... node #2, CPUs: #8 #9 #10 #11
.... node #3, CPUs: #12 #13 #14 #15
x86: Booted up 4 nodes, 16 CPUs"
* 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/boot: Further compress CPUs bootup message
x86: Improve the printout of the SMP bootup CPU table
