    SubjectRe: [ckrm-tech] [PATCH 1/6] BC: kconfig
    > Is there a reason why these can be moved to a arch-neutral place ?
    I think a good place for BC would be kernel/Kconfig.bc
    but still this should be added into archs.
    ok?

    > PS: Please keep ckrm-tech on Cc: please.
    Sorry, it is very hard to track emails coming from authors and 3 mailing lists.
    Better tell me the interested people emails.

    Thanks,
    Kirill
