Subject: init: introduce DEBUG_MISC option
Patch series "init: Do not select DEBUG_KERNEL by default", v5.
CONFIG_DEBUG_KERNEL has been designed to just enable Kconfig options.
Kernel code generatoin should not depend on CONFIG_DEBUG_KERNEL.
Proposed alternative plan: let's add a new symbol, something like
DEBUG_MISC ("Miscellaneous debug code that should be under a more specific
debug option but isn't"), make it depend on DEBUG_KERNEL and be "default
DEBUG_KERNEL" but allow itself to be turned off, and then mechanically
change the small handful of "#ifdef CONFIG_DEBUG_KERNEL" to "#ifdef
CONFIG_DEBUG_MISC".
This patch (of 5):
Introduce DEBUG_MISC ("Miscellaneous debug code that should be under a
more specific debug option but isn't"), make it depend on DEBUG_KERNEL and
be "default DEBUG_KERNEL" but allow itself to be turned off, and then
mechanically change the small handful of "#ifdef CONFIG_DEBUG_KERNEL" to
"#ifdef CONFIG_DEBUG_MISC".
