Commit 0160928e authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'edac_for_3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp

Pull EDAC updates from Borislav Petkov:
 "EDAC updates all over the place:

   - Enablement for AMD F15h models 0x60 CPUs.  Most notably DDR4 RAM
     support.  Out of tree stuff is adding the required PCI IDs.  From
     Aravind Gopalakrishnan.

   - Enable amd64_edac for 32-bit due to popular demand.  From Tomasz
     Pala.

   - Convert the AMD MCE injection module to debugfs, where it belongs.

   - Misc EDAC cleanups"
