CONFIG_BASE_FULL is equivalent to !CONFIG_BASE_SMALL and is enabled by
default: CONFIG_BASE_SMALL is the special case to take care of.
So, remove CONFIG_BASE_FULL and move the config choice to
CONFIG_BASE_SMALL (which defaults to 'n')
For defconfigs explicitely disabling BASE_FULL, explicitely enable
BASE_SMALL.
For defconfigs explicitely enabling BASE_FULL, drop it as it is the
default.

SLUB is now the only remaining allocator after the SLAB removal and it
was the default already before that, so no need to mention it in the
defconfig files.

As part of general housekeeping, change the defconfig files to
sort lines based on the 'make savedefconfig' output, to make

As explained in [1], we would like to remove SLOB if possible.
- There are no known users that need its somewhat lower memory footprint
so much that they cannot handle SLUB (after some modifications by the
previous patches) instead.
- It is an extra maintenance burden, and a number of features are
incompatible with it.
- It blocks the API improvement of allowing kfree() on objects allocated
via kmem_cache_alloc().
As the first step, rename the CONFIG_SLOB option in the slab allocator
configuration choice to CONFIG_SLOB_DEPRECATED. Add CONFIG_SLOB
depending on CONFIG_SLOB_DEPRECATED as an internal option to avoid code
churn. This will cause existing .config files and defconfigs with
CONFIG_SLOB=y to silently switch to the default (and recommended
replacement) SLUB, while still allowing SLOB to be configured by anyone
that notices and needs it. But those should contact the slab maintainers
and linux-mm@kvack.org as explained in the updated help. With no valid
objections, the plan is to update the existing defconfigs to SLUB and
remove SLOB in a few cycles.
To make SLUB more suitable replacement for SLOB, a CONFIG_SLUB_TINY
option was introduced to limit SLUB's memory overhead.
There is a number of defconfigs specifying CONFIG_SLOB=y. As part of
this patch, update them to select CONFIG_SLUB and CONFIG_SLUB_TINY.

The top-level platform selection is mostly meaningless these days after
almost everything is sorted below the CONFIG_ARCH_MULTIPLATFORM, with
the only exception being the 20+ year old StrongARM based machines.
Make this more consistent by removing the entire choice statement and
moving the StrongARM specific options into regular platform specific
Kconfig files.
The three platforms (footbridge, rpc and sa1100) are still mutually
exclusive and cannot coexist with other ARMv4/v5 machines, but since
there are only three of them and we will not add more, this can be
expressed using Kconfig 'depends on' statements.

The default is always 0x0 after commit 39c3e30456 ("ARM: 8984/1:
Kconfig: set default ZBOOT_ROM_TEXT/BSS value to 0x0"), so any
defconfig file that has these two lines can now drop them to reduce
the diff against the 'make savedefconfig' version.

A lot of Kconfig options have changed over the years, and we tend
to not do a blind 'make defconfig' to refresh the files, to ensure
we catch options that should not have gone away.
I used some a bit of scripting to only rework the bits where an
option moved around in any of the defconfig files, without also
dropping any of the other lines, to make it clearer which options
we no longer have.

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively. However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers. This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:
* testing efforts are divided between two subsystems
* having duplicate drivers for same hardware confuses users
This patch converts collie_defconfig to use libata PATA
drivers.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
