Merge tag 'kconfig-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kconfig updates from Masahiro Yamada:
- allow only 'config', 'comment', 'if' statements inside 'choice' since
the other statements are not sensible inside 'choice' and should be
grammatical error
- support LMC_KEEP env variable for 'make local{yes,mod}config' to
preserve some CONFIG options
- deprecate 'make kvmconfig' and 'make xenconfig' in favor of
'make kvm_guest.config' and 'make xen.config'
- code cleanups
* tag 'kconfig-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
kconfig: announce removal of 'kvmconfig' and 'xenconfig' shorthands
streamline_config.pl: add LMC_KEEP to preserve some kconfigs
kconfig: allow only 'config', 'comment', and 'if' inside 'choice'
kconfig: tests: remove randconfig test for choice in choice
kconfig: do not assign a variable in the return statement
kconfig: do not use OR-assignment for zero-cleared structure
