Use "select" to ensure that the required kconfig symbols are set
as expected.
Drop HOSTAUDIO since it is now equivalent to UML_SOUND.
Set CONFIG_SOUND=m in ARCH=um defconfig files to maintain the
status quo of the default configs.
Allow SOUND with UML regardless of HAS_IOMEM. Otherwise there is a
kconfig warning for unmet dependencies. (This was not an issue when
SOUND was defined in arch/um/drivers/Kconfig. I have done 50 randconfig
builds and didn't find any issues.)
This fixes build errors when CONFIG_SOUND is not set:
ld: arch/um/drivers/hostaudio_kern.o: in function `hostaudio_cleanup_module':
hostaudio_kern.c:(.exit.text+0xa): undefined reference to `unregister_sound_mixer'
ld: hostaudio_kern.c:(.exit.text+0x15): undefined reference to `unregister_sound_dsp'

Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.
Get rid of it mechanically:
git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'
Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

As discussed at LSF/MM [1] [2] and with no objections raised there,
deprecate the SLAB allocator. Rename the user-visible option so that
users with CONFIG_SLAB=y get a new prompt with explanation during make
oldconfig, while make olddefconfig will just switch to SLUB.
In all defconfigs with CONFIG_SLAB=y remove the line so those also
switch to SLUB. Regressions due to the switch should be reported to
linux-mm and slab maintainers.

CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.
This was actually not what I had in mind when I suggested making it a
'choice' statement, but it's too late to change again now, and the Kconfig
logic is more sensible in the new form.
Change any defconfig file that had CONFIG_DEBUG_INFO enabled but did not
pick DWARF4 or DWARF5 explicitly to now pick the toolchain default.

The default .kunitconfig file is currently kept in
arch/um/configs/kunit_defconfig, but -- with the impending QEMU patch
-- will no-longer be exclusively used for UML-based kernels.
Move it alongside the other KUnit configs in
tools/testing/kunit/configs, and give it a name which matches the
existing all_tests.config and broken_on_uml.config files.
Also update the Getting Started documentation to point to the new file.

Make the default .kunitconfig (specified in
arch/um/configs/kunit_defconfig) specify CONFIG_KUNIT_ALL_TESTS by
default. KUNIT_ALL_TESTS runs all tests which have satisfied
dependencies in the current .config (which would be the architecture
defconfig).
Currently, the default .kunitconfig enables only the example tests and
KUnit's own tests. While this does provide a good example of what a
.kunitconfig for running a few individual tests should look like, it
does mean that kunit_tool runs a pretty paltry collection of tests by
default.
The example tests' config entry (CONFIG_KUNIT_EXAMPLE_TEST=y) continues
to be included -- despite now being redundant -- to provide an example
of how tests are enabled when KUNIT_ALL_TESTS is disabled.
A default run of ./tools/testing/kunit/kunit.py run now runs 70 tests
instead of 14.

Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
made default to 'n',
2. It is not recommended (help message: "This should not be used today
[...] creates a high system load") and was kept only for ancient
userland,
3. Certain userland specifically requests it to be disabled (systemd
README: "Legacy hotplug slows down the system and confuses udev").

arch/um/defconfig only lists one default configuration, and that applies
only to the i386 architecture. Replace it with two minimal
configuration files generated using `make savedefconfig`:
i386_defconfig and x86_64_defconfig
The build scripts now require two updates:
1. um's Kconfig (arch/x86/um/Kconfig) should specify an ARCH_DEFCONFIG
section explicitly pointing to these scripts if the required
variables are set. Take care to remove the DEFCONFIG_LIST section
defined in the included file arch/um/Kconfig.common.
2. um's Makefile (arch/um/Makefile) should set KBUILD_DEFCONFIG properly
for the top-level Makefile to pick up. Copy the logic in
arch/x86/Makefile to properly pick the defconfig file depending on
the actual architecture; except we're working with $SUBARCH here,
instead of $ARCH.
Now, you can do:
$ ARCH=um make defconfig
$ ARCH=um make
and successfully build User-Mode Linux on an x86_64 box in default
configuration.
