Merge tag 'kconfig-v4.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kconfig consolidation from Masahiro Yamada:
"Consolidation of Kconfig files by Christoph Hellwig.
Move the source statements of arch-independent Kconfig files instead
of duplicating the includes in every arch/$(SRCARCH)/Kconfig"
* tag 'kconfig-v4.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
kconfig: add a Memory Management options" menu
kconfig: move the "Executable file formats" menu to fs/Kconfig.binfmt
kconfig: use a menu in arch/Kconfig to reduce clutter
kconfig: include kernel/Kconfig.preempt from init/Kconfig
Kconfig: consolidate the "Kernel hacking" menu
kconfig: include common Kconfig files from top-level Kconfig
kconfig: remove duplicate SWAP symbol defintions
um: create a proper drivers Kconfig
um: cleanup Kconfig files
um: stop abusing KBUILD_KCONFIG
