From 93ae5012a79b11e7fc855b52c7ce1e16fe1540b0 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Thu, 15 Oct 2009 14:21:14 -0700 Subject: x86: Don't print number of MCE banks for every CPU The MCE initialization code explicitly says it doesn't handle asymmetric configurations where different CPUs support different numbers of MCE banks, and it prints a big warning in that case. Therefore, printing the "mce: CPU supports MCE banks" message into the kernel log for every CPU is pure redundancy that clutters the log significantly for systems with lots of CPUs.
