Thanks Neil, I use both, especially if grepping does not reveal what I am 
looking for.

Yes, I got (almost) the same and it shows that MICROCODE is a top level 
module, but I can't see it when I walk through the 'Processor type and 
features' contents.  Fine, my eyesight is not what it used to be, but it can't 
be this bad!  :p

Symbol: MICROCODE [=n] 
Type  : boolean  
Prompt: CPU microcode loading support  
  Location:  
(1) -> Processor type and features  
  Defined at arch/x86/Kconfig:1125  
  Depends on: (CPU_SUP_AMD [=y] || CPU_SUP_INTEL [=y]) && BLK_DEV_INITRD 
  Selects: FW_LOADER [=y]

I built this 4.4.6 kernel with oldconfig, so it *should* retain previously 
selected modules, like MICROCODE.  Either way, why would it not show in 
menuconfig, if a search says it is?
