Merge tag 'ras_for_3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp into x86/ras
Pull RAS updates from Borislav Petkov: * Add the functionality to override error reporting agents as some machines are sporting a new extended error logging capability which, if done properly in the BIOS, makes a corresponding EDAC module redundant, from Gong Chen. * PCIe AER tracepoint severity levels fix, from Rui Wang. * Error path correction for the mce device init, from Levente Kurusa.
