lib/crc32: remove obsolete CRC32 options from defconfig files

Remove all remaining references to CONFIG_CRC32_BIT,
CONFIG_CRC32_SARWATE, CONFIG_CRC32_SLICEBY4, and CONFIG_CRC32_SLICEBY8.
These options no longer exist, now that we've standardized on a single
generic CRC32 implementation.

printk: Remove redundant CONFIG_BASE_FULL

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.

powerpc: Restore CONFIG_DEBUG_INFO in defconfigs

Commit f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a
choice") broke the selection of CONFIG_DEBUG_INFO by powerpc defconfigs.

It is now necessary to select one of the three DEBUG_INFO_DWARF*
options to get DEBUG_INFO enabled.

Replace DEBUG_INFO=y by DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y in all
defconfigs using the following command:

sed -i s/DEBUG_INFO=y/DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y/g `git grep -l DEBUG_INFO arch/powerpc/configs/`

powerpc/8xx: Drop CONFIG_8xx_COPYBACK option

CONFIG_8xx_COPYBACK was there to help disabling copyback cache mode
for debuging hardware. But nobody will design new boards with 8xx now.

All 8xx platforms select it, so make it the default and remove
the option.

Also remove the Mx_RESETVAL values which are pretty useless and hide
the real value while reading code.

It looks like it's ~4 years since we updated some of these, so do a bulk

Verified that the before and after generated configs are exactly the

Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

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.
