Subject: kconfig: tinyconfig: provide whole choice blocks to avoid warnings
From: Arnd Bergmann <[email protected]>
commit 236dec051078a8691950f56949612b4b74107e48 upstream.
Using "make tinyconfig" produces a couple of annoying warnings that show up for build test machines all the time:
.config:966:warning: override: NOHIGHMEM changes choice state .config:965:warning: override: SLOB changes choice state .config:963:warning: override: KERNEL_XZ changes choice state .config:962:warning: override: CC_OPTIMIZE_FOR_SIZE changes choice state .config:933:warning: override: SLOB changes choice state .config:930:warning: override: CC_OPTIMIZE_FOR_SIZE changes choice state .config:870:warning: override: SLOB changes choice state .config:868:warning: override: KERNEL_XZ changes choice state .config:867:warning: override: CC_OPTIMIZE_FOR_SIZE changes choice state
I've made a previous attempt at fixing them and we discussed a number of alternatives.
I tried changing the Makefile to use "merge_config.sh -n $(fragment-list)" but couldn't get that to work properly.
This is yet another approach, based on the observation that we do want to see a warning for conflicting 'choice' options, and that we can simply make them non-conflicting by listing all other options as disabled. This is a trivial patch that we can apply independent of plans for other changes.
