Well this does seem like a "clever" way out of the randconfig
problem. New patch applies and when I set .config to have:
CONFIG_EDAC_DEBUG=y
CONFIG_EDAC_SKX=y
CONFIG_EDAC_I10NM=m
CONFIG_EDAC_SKX_COMMON=y
I don't see any build errors.
There are lots of "skx_" symbols in System.map
But I'm not at all sure what happened to the I10NM driver.
I don't see it mentioned in the output from "make".
It didn't get built as a module (no ".ko" file for it).
It doesn't seem to be built in (no ".o" in drivers/edac/built-in.a)
So I added a #error line to the start of i10nm_edac.c and
ran "make" again. Nothing.
So, I don't think this is doing what you think it should
do. Even if it did, it would seem very confusing to a user
that asked for "one module, one built-in" in Kconfig, but
found both built-in.
Boris: I'm voting for Qiuxu's most recent solution (moving
all the EDAC_DEBUG bits out of skx_common.c).
