Subject: linux-next: build failure after merge of the edac-amd tree

Hi Borislav,

After merging the edac-amd tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/edac/xgene_edac.c: In function 'xgene_edac_pmd_l2c_version1':
drivers/edac/xgene_edac.c:792:2: error: implicit declaration of function 'MIDR_VARIANT' [-Werror=implicit-function-declaration]

                                     ^

Caused by commit  ("EDAC: Add APM X-Gene SoC EDAC driver").  You can't
use COMPIlE_TEST for drivers that use arch specific APIs ...

I have used the edac-amd tree from next-20150529 for today.
