          Some drivers can be compiled on a different platform than they are
          intended to be run on. Despite they cannot be loaded there (or even
          when they load they cannot be used due to missing HW support),
          developers still, opposing to distributors, might want to build such
          drivers to compile-test them.

          If you are a developer and want to build everything available, say Y
          here. If you are a user/distributor, say N here to exclude useless
          drivers to be distributed.

I guess, 'COMPILE_TEST' is really useful for UML.

No.

We have explained you more than once what the deal and why UML does not
have ioremap() and friends.

This time, it is not for UML, it is for 'COMPILE_TEST': the
'asm-generic' whether need consider it.


Thanks.
