Hi,

Very sorry for long distance between my previous post and this...

I wrote a patch to add HAVE_READQ and HAVE_WRITEQ to each architecture's Kconfig file
which have readq() and writeq().

But there is problem.
I wrote helps for HAVE_READQ and HAVE_WRITEQ in Kconfig file
accodring to the advice by Russell King ( http://marc.info/?l=linux-kernel&m=122701161824218&w=2 ),
but these helps are invisible when I doing menuconfig.
(when type '/' and search readq string, HAVE_READQ found, but
help string is not printed...)

Do you have some nice technique that make these helps visible easily?
I paste a patch for x86 as sample. If I could find a good way,
I'll rewrite patches and send them to maintainers of each architectures.
