Merge tag 'edac_for_4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp 

Pull EDAC updates from Borislav Petkov:

 - hide EDAC workqueue from users (Borislav Petkov)

 - edac_subsys init/teardown cleanup (Borislav Petkov)

 - make mpc85xx-pci-edac a platform device (Scott Wood)

 - sb_edac KNL gen2 support (Jim Snow)

 - other small cleanups all over the place

EDAC - Error Detection And Correction
=====================================
"bluesmoke" was the name for this device driver when it was "out-of-tree"
and maintained at sourceforge.net. When it was pushed into 2.6.16 for the
first time, it was renamed to 'EDAC'.
"bluesmoke" was the name for this device driver when it
was "out-of-tree" and maintained at sourceforge.net -
bluesmoke.sourceforge.net. That site is mostly archaic now and can be
used only for historical purposes.
When the subsystem was pushed into 2.6.16 for the first time, it was
renamed to 'EDAC'.
