Instead of exposing the arm-optimized SHA-1 code via arm-specific
crypto_shash algorithms, instead just implement the sha1_blocks()
library function. This is much simpler, it makes the SHA-1 library
functions be arm-optimized, and it fixes the longstanding issue where
the arm-optimized SHA-1 code was disabled by default. SHA-1 still
remains available through crypto_shash, but individual architectures no
longer need to handle it.
To match sha1_blocks(), change the type of the nblocks parameter of the
assembly functions from int to size_t. The assembly functions actually
already treated it as size_t.

As a preparation for adding support for Samsung's S2MPG10, which is
connected via SPEEDY / ACPM rather than I2C, split out (move) all
I2C-specific driver code into its own kernel module, sec-i2c, and
make the existing sec-core module be just the transport-agnostic core
driver kernel module.
At the same time, update all defconfigs that reference the old kconfig
symbol name.
While at it, also update file header comments and module description(s)
to drop references to 'mfd', and update comments to be C-style, not

Instead of providing crypto_shash algorithms for the arch-optimized
SHA-256 code, instead implement the SHA-256 library. This is much
simpler, it makes the SHA-256 library functions be arch-optimized, and
it fixes the longstanding issue where the arch-optimized SHA-256 was
disabled by default. SHA-256 still remains available through
crypto_shash, but individual architectures no longer need to handle it.
To merge the scalar, NEON, and CE code all into one module cleanly, add
!CPU_V7M as a direct dependency of the CE code. Previously, !CPU_V7M
was only a direct dependency of the scalar and NEON code. The result is
still the same because CPU_V7M implies !KERNEL_MODE_NEON, so !CPU_V7M
was already an indirect dependency of the CE code.
To match sha256_blocks_arch(), change the type of the nblocks parameter
of the assembly functions from int to size_t. The assembly functions
actually already treated it as size_t.
While renaming the assembly files, also fix the naming quirk where
"sha2" meant sha256. (SHA-512 is also part of SHA-2.)

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

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.

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.

Commit 06b93644f4 ("media: Kconfig: add an option to filter in/out

on the new CONFIG_MEDIA_PLATFORM_SUPPORT symbol, so add it also to
exynos_defconfig. While touching this part, update the media related
configs to the current layout.

Most CEC platform drivers are using VIDEO_*_CEC pattern, some with
an _HDMI extension too.
Well, they're not related to V4L2 support, and we don't really
need those big config names. So drop VIDEO_* from them, remove
_HDMI (if present) and move CEC to the start.
This way, all platform driver options are now CEC_<driver>.

MAC80211/CFG80211 framework requires loading regulatory.db from
/lib/firmware directory, so it makes very little sense to have it
built-in. Change it to be built as modules to let it properly load the
needed firmware/db files. As a side effect of this change, the size of
the compressed modules on SquashFS increased significantly from 27MiB
to 38MiB, so increase the size of BLK_DEV_RAM to allow the modules to
fit into it.

The Energy Model (EM) is needed to run Energy Aware Scheduler (EAS).
Enable ENERGY_MODEL to make that happen. This will increase energy
efficiency of the big.LITTLE platforms (e.g. Exynos5422) by smarter

Add SCHED_MC in order to create another level in scheduling domains: 'MC'.

We keep this in a separate branch to avoid cross-branch conflicts, but

for hardware since they were merged, and some refreshed files due to
time having moved a lot of entries around.

Few options KALLSYMS_ALL, SCSI, PM_DEVFREQ and mutex/spinlock debugging
were removed with savedefconfig because they were selected by other
options. However these are user-visible options and they might not be
selected in the future. Exactly this happened with commit 0e4a459f56
("tracing: Remove unnecessary DEBUG_FS dependency") removing the
dependency between DEBUG_FS and TRACING.
To avoid losing these options in the future, explicitly mention them in

Commit 9f532d26c7 ("ARM: exynos_defconfig: Trim and reorganize with

that feature has been selected by other enabled options: CONFIG_TRACING,
which in turn had been selected by CONFIG_PERF_EVENTS and
CONFIG_PROVE_LOCKING.
In meantime, commit 0e4a459f56 ("tracing: Remove unnecessary DEBUG_FS
dependency") removed the dependency between CONFIG_DEBUG_FS and
CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds.

Some big.LITTLE systems have I-Cache line size mismatch between
LITTLE and big cores. This patch adds a workaround for proper I-Cache
support on such systems. Without it, some class of the userspace code
(typically self-modifying) might suffer from random SIGILL failures.
Similar workaround already exists for ARM64 architecture. I has been
added by commit 116c81f427 ("arm64: Work around systems with mismatched
