Kconfig: consolidate the "Kernel hacking" menu
Move the source of lib/Kconfig.debug and arch/$(ARCH)/Kconfig.debug to the top-level Kconfig. For two architectures that means moving their arch-specific symbols in that menu into a new arch Kconfig.debug file, and for a few more creating a dummy file so that we can include it unconditionally. Also move the actual 'Kernel hacking' menu to lib/Kconfig.debug, where it belongs. Signed-off-by: Christoph Hellwig <> Signed-off-by: Masahiro Yamada <>

+ bool "Built-in kernel command line"
+ help
+ For most platforms, it is firmware or second stage bootloader
+ that by default specifies the kernel command line options.
+ However, it might be necessary or advantageous to either override
+ the default kernel command line or add a few extra options to it.
+ For such cases, this option allows hardcoding command line options
+ directly into the kernel.
+ For that, choose 'Y' here and fill in the extra boot parameters
+ The built-in options will be concatenated to the default command
+ line if CMDLINE_FORCE is set to 'N'. Otherwise, the default
+ command line will be ignored and replaced by the built-in string.

+ Set this option to 'Y' to have the kernel ignore the bootloader
+ or firmware command line. Instead, the built-in command line
+ will be used exclusively.
+ If you don't know what to do here, say N.
