EDAC/dmc520: Assign the proper type to dimm->edac_mode

2021-09-30T08:13:07+00:00

commit 54607282fae6148641a08d81a6e0953b541249c7 upstream. dimm->edac_mode contains values of type enum edac_type - not the corresponding capability flags. Fix that.

EDAC/i10nm: Fix NVDIMM detection

2021-09-15T08:02:09+00:00

[ Upstream commit 2294a7299f5e51667b841f63c6d69474491753fb ] MCDDRCFG is a per-channel register and uses bit{0,1} to indicate the NVDIMM presence on DIMM slot{0,1}. Current i10nm_edac driver wrongly uses MCDDRCFG as per-DIMM register and fails to detect the NVDIMM. Fix it by reading MCDDRCFG as per-channel register and using its bit{0,1} to check whether the NVDIMM is populated on DIMM slot{0,1}.

EDAC/mce_amd: Do not load edac_mce_amd module on guests

2021-09-15T08:02:02+00:00

[ Upstream commit 767f4b620edadac579c9b8b6660761d4285fa6f9 ] Hypervisors likely do not expose the SMCA feature to the guest and loading this module leads to false warnings. This module should not be loaded in guests to begin with, but people tend to do so, especially when testing kernels in VMs. And then they complain about those false warnings. Do the practical thing and do not load this module when running as a guest to avoid all that complaining.

kernel.h: split out panic and oops helpers

2021-07-01T18:06:04+00:00

kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.
