4.6.1 KVM guests boot with "amd64_edac_mod: Unknown symbol" errors on AMD 64-bit platforms

The following repeated errors might be displayed when KVM guests are booting on AMD 64-bit systems:

[   12.474069] amd64_edac_mod: Unknown symbol amd_register_ecc_decoder (err
0)
[   12.474083] amd64_edac_mod: Unknown symbol amd_report_gart_errors (err 0)
[   12.852250] amd64_edac_mod: Unknown symbol amd_unregister_ecc_decoder (err
0)
[   12.852297] amd64_edac_mod: Unknown symbol amd_register_ecc_decoder (err
0)
.
.
.

These errors occur because the module code for the kernel erroneously returns -EEXIST for modules that failed to load and are in the process of being removed from the module list. The amd64_edac_mod module will not be loaded in a VM. These errors can be ignored, as they do not impact functionality in any way.
