The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

 - drop EXPERIMENTAL from bool and help text too.

Please do not change the text this way.
The fact that CONFIG_EXPERIMENTAL is going away it doesn't change the
fact that this feature is experimental.
Maybe you want to replace EXPERIMENTAL with experimental, or if
experimental has become as taboo word, I am sure you can find a suitable
synonym.

Ah, sorry, I misunderstood what was being recommended from the other
thread (quoting below...)

It certainly is unstable right now (which is why it was unstaged from
the v3.9 train). I hope that by v3.10 it won't be - at which
point this patch (and the EXPERIMENTAL) makes sense.

Only "depends on EXPERIMENTAL" must go away. Did you want either the
bool or help text to go away too? If neither, my original patch should
work. If you only want the bool text gone, I can send that version
instead.

I think your original patch is good, but I'll let Konrad decide.
