      edac: add a new per-dimm API and make the old per-virtual-rank API obsolete · 19974710
      Mauro Carvalho Chehab authored 
      The old EDAC API is broken. It only works fine for systems manufatured
before 2005 and for AMD 64. The reason is that it forces all memory
controller drivers to discover rank info.

Also, it doesn't allow grouping the several ranks into a DIMM.

So, what almost all modern drivers do is to create a fake virtual-rank
information, and use it to cheat the EDAC core to accept the driver.

While this works if the user has enough time to discover what DIMM slot
corresponds to each "virtual-rank" information, it prevents EDAC usage
for users with less available time. It also makes life hard for vendors
that may want to provide a table with their motherboards to the userspace
tool (edac-utils) as each driver has its own logic for the virtual
mapping.

So, the old API should be removed, in favor of a more flexible API that
allows newer drivers to not lie to the EDAC core.

      EDAC, MCE: Rework MCE injection · 9cdeb404
      Borislav Petkov authored 
      Add sysfs injection facilities for testing of the MCE decoding code.
Remove large parts of amd64_edac_dbg.c, as a result, which did only
NB MCE injection anyway and the new injection code supports that
functionality already.

Add an injection module so that MCE decoding code in production kernels
like those in RHEL and SLES can be tested.

      x86: EDAC: carve out AMD MCE decoding logic · 0d18b2e3
      Borislav Petkov authored 
      This converts the MCE decoding logic into a standalone config
option which can be built-in or a module, the first one being the
default for MCEs happening early on in the boot process.

This, beyond being separated in a cleaner way, also saves RAM by
making the decoding logic modular.

      -tip testing found the following build failure (config attached):

the AMD EDAC code has a dependency on CONFIG_CPU_SUP_AMD facilities. The
patch below solves the problem here.

      powerpc/cell: add QPACE as a separate Cell platform · def434c2
      Benjamin Krill authored 
      Since the QPACE (Chromodynamics Parallel Computing on the
Cell Broadband Engine) platform doesn't use a iommu, doesn't
have PCI devices and a MPIC much lesser setup and
configurations are needed. So far all devices are detected
as OF device. A notifier function is used to set the dma_ops
for the of_platform bus. Further this patch splits the
PPC_CELL_NATIVE into PPC_CELL_COMMON which are parts that are
shared with the QPACE platform and the rest.
