From 2d144e63098be47c21ad59d68a4fd17bd73a3aaf Mon Sep 17 00:00:00 2001 From: Venki Pallipadi Date: Tue, 24 Jun 2008 17:12:56 -0700 Subject: x86, mce_64.c: mce_cpu_quirks being ignored Quirks getting ignored was a bug. Below patch fixes the bug, until we have the dynamic banks support. Sysfs choice configuration should not have any issues with the earlier patch as we look for NR_SYSFS_BANKS in do_machine_check().
