Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp
Pull EDAC fixes from Borislav Petkov: - EDAC core error path fix, from Denis Kirjanov. - Generalization of AMD MCE bank names and some minor error reporting improvements. - EDAC core cleanups and simplifications, from Wei Yongjun. - amd64_edac fixes for sysfs-reported values, from Josh Hunt. - some heavy amd64_edac error reporting path shaving, leading to removing a bunch of code. - amd64_edac error injection method improvements. - EDAC core cleanups and fixes * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp: (24 commits) EDAC, pci_sysfs: Use for_each_pci_dev to simplify the code EDAC: Handle error path in edac_mc_sysfs_init() properly MCE, AMD: Dump error status MCE, AMD: Report decoded error type first MCE, AMD: Dump CPU f/m/s triple with the error MCE, AMD: Remove functional unit references EDAC: Convert to use simple_open() EDAC, Calxeda highbank: Convert to use simple_open() EDAC: Fix mc size reported in sysfs EDAC: Fix csrow size reported in sysfs EDAC: Pass mci parent EDAC: Add memory controller flags amd64_edac: Fix csrows size and pages computation amd64_edac: Use DBAM_DIMM macro amd64_edac: Fix K8 chip select reporting amd64_edac: Reorganize error reporting path amd64_edac: Do not check whether error address is valid amd64_edac: Improve error injection amd64_edac: Cleanup error injection code amd64_edac: Small fixlets and cleanups ...
