Clean up config files by:
  - removing configs that were deleted in the past
  - removing configs not in tree and without recently pending patches
  - adding new configs that are replacements for old configs in the file

For some detailed information, see Link.

Ideally I'd like a list in the change log of each symbol and why they're
being removed/changed. It's pretty easy to accidentally drop something
otherwise.

I think this is the list in this case:

Renamed:
  - CONFIG_PPC_PTDUMP -> CONFIG_GENERIC_PTDUMP
    e084728393a5 ("powerpc/ptdump: Convert powerpc to GENERIC_PTDUMP")

Removed:
  - CONFIG_BLK_DEV_CRYPTOLOOP
    47e9624616c8 ("block: remove support for cryptoloop and the xor transfer")

  - CONFIG_CRYPTO_RMD128
    b21b9a5e0aef ("crypto: rmd128 - remove RIPE-MD 128 hash algorithm")

  - CONFIG_CRYPTO_RMD256
    c15d4167f0b0 ("crypto: rmd256 - remove RIPE-MD 256 hash algorithm")

  - CONFIG_CRYPTO_RMD320
    93f64202926f ("crypto: rmd320 - remove RIPE-MD 320 hash algorithm")

  - CONFIG_CRYPTO_SALSA20
    663f63ee6d9c ("crypto: salsa20 - remove Salsa20 stream cipher algorithm")

  - CONFIG_CRYPTO_TGR192
    87cd723f8978 ("crypto: tgr192 - remove Tiger 128/160/192 hash algorithms")

  - CONFIG_HARDENED_USERCOPY_PAGESPAN
    1109a5d90701 ("usercopy: Remove HARDENED_USERCOPY_PAGESPAN")

  - CONFIG_RAPIDIO_TSI568, CONFIG_RAPIDIO_TSI57X
    612d4904191f ("rapidio: remove not used code about RIO_VID_TUNDRA")

  - CONFIG_RAW_DRIVER
    603e4922f1c8 ("remove the raw driver")

  - CONFIG_ROCKETPORT
    3b00b6af7a5b ("tty: rocket, remove the driver")

  - CONFIG_ENABLE_MUST_CHECK
    196793946264 ("Compiler Attributes: remove CONFIG_ENABLE_MUST_CHECK")


I'll fold that into the change log.

Sure. Go ahead. I have provided all information I collected in the
linked email (and this information drove my scripts to take actions)
and I am happy to provide it in any form a maintainer may think is
good for them. But I assume you did this with a simple script
yourself.

After going through the changes of Kconfig from the last decade, it
seems feasible that the information on Kconfig changes is actually
maintained somewhere and that would allow updating of arbitrary kernel
configs to newer kernel versions. It is not completely out of reach at
least.

And to really improve the situation, I would like to reduce all these
defconfigs in the repository to minimal kernel fragments that really
focus on what these config for specific machines intend to tell. E.g.,
these configs below (powerpc-configs) are about ensuring specific
hardware support, not about setting "CONFIG_CRYPTO_XYZ" one way or the
other. That is actually just "noise". I do not know how to do this
right yet, but with a bit of experimentation and investigation, I
might come with a first idea and then we will see.

Lukas

cheers
