From ee031c31d6381d004bfd386c2e45821211507499 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Thu, 12 Feb 2009 13:49:34 +0100 Subject: x86, mce, cmci: use polled banks bitmap in machine check poller Define a per cpu bitmap that contains the banks polled by the machine check poller. This is needed for the CMCI code in the next patches to be able to disable polling on specific banks. The bank by default contains all banks, so there is no behaviour change. Only future code will remove some banks from the polling set. Signed-off-by: Andi Kleen Signed-off-by: H.
