Pull RAS updates from Ingo Molnar: "Various RAS updates: - AMD MCE support updates for future CPUs, fixes and 'SMCA' (Scalable MCA) error decoding support (Aravind Gopalakrishnan) - x86 memcpy_mcsafe() support, to enable smart(er) hardware error recovery in NVDIMM drivers, based on an extension of the x86 exception handling code. (Tony Luck)" * 'ras-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: EDAC/sb_edac: Fix computation of channel address x86/mm, x86/mce: Add memcpy_mcsafe() x86/mce/AMD: Document some functionality x86/mce: Clarify comments regarding deferred error x86/mce/AMD: Fix logic to obtain block address x86/mce/AMD, EDAC: Enable error decoding of Scalable MCA errors x86/mce: Move MCx_CONFIG MSR definitions x86/mce: Check for faults tagged in EXTABLE_CLASS_FAULT exception table entries x86/mm: Expand the exception table logic to allow new handling options x86/mce/AMD: Set MCAX Enable bit x86/mce/AMD: Carve out threshold block preparation x86/mce/AMD: Fix LVT offset configuration for thresholding x86/mce/AMD: Reduce number of blocks scanned per bank x86/mce/AMD: Do not perform shared bank check for future processors x86/mce: Fix order of AMD MCE init function call
