From: Roland Dreier Date: Thu, 15 Oct 2009 21:21:14 +0000 (-0700) Subject: x86: Don't print number of MCE banks for every CPU X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93ae5012a79b11e7fc855b52c7ce1e16fe1540b0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
