Subject: kconfig: include common Kconfig files from top-level Kconfig
Instead of duplicating the source statements in every architecture just
do it once in the toplevel Kconfig file.
Note that with this the inclusion of arch/$(SRCARCH/Kconfig moves out of
the top-level Kconfig into arch/Kconfig so that don't violate ordering
constraits while keeping a sensible menu structure.

Subject: 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.

+ 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
+ in CONFIG_CMDLINE.
+
+ 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.

From 87a4c375995ed8eaa721b08825cf73d0b02b3145 Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Tue, 31 Jul 2018 13:39:32 +0200
Subject: kconfig: include kernel/Kconfig.preempt from init/Kconfig
Almost all architectures include it. Add a ARCH_NO_PREEMPT symbol to
disable preempt support for alpha, hexagon, non-coldfire m68k and
user mode Linux.
