From 140f190bc3a3b6f200548d204befd998eadd63fd Mon Sep 17 00:00:00 2001 From: "Luck, Tony" Date: Wed, 22 Feb 2012 10:06:44 -0800 Subject: [PATCH] x86: Remove some noise from boot log when starting cpus Printing the "start_ip" for every secondary cpu is very noisy on a large system - and doesn't add any value. Drop this message. Console log before: Booting Node 0, Processors #1 smpboot cpu 1: start_ip = 96000 #2 smpboot cpu 2: start_ip = 96000 #3 smpboot cpu 3: start_ip = 96000 #4 smpboot cpu 4: start_ip = 96000 ... #31 smpboot cpu 31: start_ip = 96000 Brought up 32 CPUs Console log after: Booting Node 0, Processors #1 #2 #3 #4 #5 #6 #7 Ok. Booting Node 1, Processors #8 #9 #10 #11 #12 #13 #14 #15 Ok. Booting Node 0, Processors #16 #17 #18 #19 #20 #21 #22 #23 Ok. Booting Node 1, Processors #24 #25 #26 #27 #28 #29 #30 #31 Brought up 32 CPUs Acked-by: Borislav Petkov Signed-off-by: Tony Luck Link: http://lkml.kernel.org/r/4f452eb42507460426@agluck-desktop.sc.intel.com Signed-off-by: H.
