Masahiro, Tom, Petr,

Thanks for your prompt feedback.

I would happily attempt that. However, see my below question.

Just to avoid any miscommunication, is my understanding correct that
this is an explicit request for Masahiro to take care of the update? I
would totally understand this.

FWIW, here is some statistics of the kernel kconfig development in the
v4.10..v4.17-rc4 commit range:

- 86 non-merge change-sets:
git rev-list --no-merges --count v4.10..v4.17-rc4 -- scripts/kconfig/
86

- 8 Kconfig commits which touch non-Kconfig files too (ignoring
  Documentation) and hence might require more delicate conflict
  resolution:

for c in $(git rev-list --reverse --no-merges v4.10..v4.17-rc4 -- scripts/kconfig/); do
  if (git log --full-diff --format="" --name-only -1 $c -- scripts/kconfig  |
    egrep -v "scripts/kconfig|Documentation" > /dev/null); then
      git --no-pager log --oneline $c -1;
  fi;
done

b23d1a241f4e kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically

I also think that the most sensitive part of this update is related to:
- changed tooling requirements for hosts, e.g. flex and bison seem to
  be required starting with commit 29c833061c1d ("kconfig: generate
  lexer and parser during build instead of shipping").
- dropped silentoldconfig support, starting with commit cedd55d49dee
  ("kconfig: Remove silentoldconfig from help and docs; fix
  kconfig/conf's help").

There might be questions from users experiencing build errors/warnings
after the update, same as we've seen in [1].

I would appreciate if Tom answers the question raised in the beginning
of my post.

Best regards,
Eugeniu.
