I usually ask for defconfig changes to be merged when someone just
adds a single line per patch, but a 144 line change is clearly too
big, please split this up.

These two hunks seem to go together, but it needs an explanation
why you are removing CONFIG_KEXEC.

No, I definitely want CONFIG_IOSCHED_BFQ=y, it is essential
for performance on certain classes of machines. It would
be better to drop the 'imply IOSCHED_BFQ' in two Kconfig
files.

These also seem kind of essential for almost any machine,
I assume you are doing something wrong here.

These just get moved around in the file, please don't

This was caused by commit 9e4e24414cc6 ("arm64:
introduce STM32 family on Armv8 architecture"),
which selects ARM_SCMI_PROTOCOL and COMMON_CLK_SCMI.
I think we should instead revert those and enable
them in the defconfig for consistency with the other
platforms that need the same driver.

For the ones that got removed for a good and trivial reason,
you can probably combine the patches and just list what
happened.

Apparently caused by GPIO_SAMA5D2_PIOBU, please change that
to 'depends on'.

DRM_EXYNOS_DSI should probably depend on this rather than
selecting it.

Again we have a mix of select and depends:

drivers/remoteproc/Kconfig:     select OMAP2PLUS_MBOX
drivers/remoteproc/Kconfig:     select OMAP2PLUS_MBOX
drivers/remoteproc/Kconfig:     select OMAP2PLUS_MBOX
drivers/soc/ti/Kconfig: depends on OMAP2PLUS_MBOX

We probably want the latter for all of them.

Please fix SOUNDWIRE_QCOM to no longer 'imply SLIMBUS'.

I think the problem here are some Tegra device drivers that
incorrectly 'select INTERCONNECT' rather than using the
'depends on' that every other interconnect driver has.
Please fix those instead.

For CONFIG_CONFIGFS_FS, we have a mix of 'depends on' and 'select'
in the Kconfig options that use it. Before you remove this here,
let's discuss with all the users which of the two should actually
be used and then change them to be consistent.

These looks sensible. Can you do the same thing for
arch/arm/configs/* in a combined patch?
