[PATCH v5 0/5] init: Do not select DEBUG_KERNEL by default

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".

Diff from v4:
- collect reviewed-by
- collect acked-by
- fix nit on 1/5

Sinan Kaya (5):
init: Introduce DEBUG_MISC option
powerpc: Replace CONFIG_DEBUG_KERNEL with CONFIG_DEBUG_MISC
mips: Replace CONFIG_DEBUG_KERNEL with CONFIG_DEBUG_MISC
xtensa: Replace CONFIG_DEBUG_KERNEL with CONFIG_DEBUG_MISC
net: Replace CONFIG_DEBUG_KERNEL with CONFIG_DEBUG_MISC
