Hi Linus,

Please pull Kconfig updates for v4.18

(The follow-up cleanup works are not included in this PR.
I will send them later on because I need to wait for
some prerequisite patches from the PowerPC subsystem.)

You will see a conflict in the top-level Makefile.
It should be resolved as follows:
(The correct fix is also available in linux-next)

------------------------------------------
diff --cc Makefile

kconfig: Avoid format overflow warning from GCC 8.1 (2018-06-05
22:07:21 +0900)

----------------------------------------------------------------
Kconfig updates for v4.18

Kconfig now supports new functionality to perform textual substitution.
It has been a while since Linus suggested to move compiler option tests
from makefiles to Kconfig. Finally, here it is. The implementation has
been generalized into a Make-like macro language. Some built-in functions
such as 'shell' are provided. Variables and user-defined functions are
also supported so that 'cc-option', 'ld-option', etc. are implemented as
macros.

Summary:

- refactor package checks for building {m,n,q,g}conf

- remove unused/unmaintained localization support

- remove Kbuild cache

- drop CONFIG_CROSS_COMPILE support

- replace 'option env=' with direct variable expansion

- add built-in functions such as 'shell'

- support variables and user-defined functions

- add helper macros as as 'cc-option'

- add unit tests and a document of the new macro language

- add 'testconfig' to help

- fix warnings from GCC 8.1
