#     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
