    ("mm/uffd: move USERFAULTFD configs into mm/")),
  - Move CONFIG_SLAB=y (moved in commit 7b42f104 ("mm: Kconfig:
    move swap and slab config options to the MM section")),
  - Replace CONFIG_ZPOOL=m by CONFIG_ZRAM=m (cfr. commit
    b3fbd58f ("mm: Kconfig: simplify zswap configuration")),
  - Replace CONFIG_CRYPTO_SM[34]=m by CONFIG_CRYPTO_SM[34]_GENERIC=m
    (cfr. commit d2825fa9 ("crypto: sm3,sm4 - move into crypto
    directory")),
  - Drop CONFIG_BITFIELD_KUNIT=m, CONFIG_BITS_TEST=m,
    CONFIG_CMDLINE_KUNIT_TEST=m, and CONFIG_RESOURCE_KUNIT_TEST=m
    (auto-modular since commit dcbb2ee2 ("lib/Kconfig.debug:
    change KUnit tests to default to KUNIT_ALL_TESTS")).
