and but yet, in linux-4.17-rc4, with this posted config file (after
using:  yes '' |make oldconfig), we can see:

WARNING: unmet direct dependencies detected for DELL_SMBIOS
  Depends on [m]: X86 [=y] && X86_PLATFORM_DEVICES [=y] && (DCDBAS [=m] || DCDBAS [=m]=n) && (ACPI_WMI [=y] || ACPI_WMI [=y]=n)

I'll stare at it some (more), but no promises.
