Prev: [PATCH -v3 2/2] x86, MCE, fix MSR_IA32_MCI_CTL2 CMCI threshold setup
Next: random: Check kmalloc return value and give the failed message
From: Huang Ying on 18 May 2010 01:40
Rename CMCI_EN to MCI_CTL2_CMCI_EN and CMCI_THRESHOLD_MASK to
MCI_CTL2_CMCI_THRESHOLD_MASK to make naming consistent.
