Al Viro da09128685 CONFIG_TR/CONFIG_LLC: work around the problem with select 
As it is, with PCI/ISA/MCA/CCW all set to n and PCMCIA set to m
setting TR to y will set LLC to m, with very unpleasant results -
net/802/psnap gets picked into obj-y, resulting in the kernel
that won't link - psnap calls functions from llc.  The cause,
AFAICS, is that kconfig gets rev_dep for LLC containing
|| TR && (deps for TR)
and even though TR is boolean, both LLC and PCMCIA are tristate
and that thing becomes || y && (n || m), i.e. || m.  The reason
for dependency on PCMCIA is that when none of PCI, ISA, MCA, CCW
or PCMCIA is set there'll be no tokenring drivers, so there's no
point building tokenring core.  Proper fix probably belongs in
kconfig (we need strict and, such that y <strict_and> m would be
y, so that rev_deps added for tristate selected by bool would
use that instead of &&; we'd have || TR <strict_and> (deps for TR)
in this case), but it's a rather intrusive change.  There's an
easy workaround in case of TR -> LLC select, namely to have a def_bool y
symbol sitting under if TR and have that symbol selecting LLC.
Kudos to johill for suggesting that one...

Token Ring is IBM's way of communication on a local network; the
rest of the world uses Ethernet. To participate on a Token Ring
network, you need a special Token ring network card. If you are
connected to such a Token Ring network and want to use your Token
Ring card under Linux, say Y here and to the driver for your
particular card below and read the Token-Ring mini-HOWTO, available
from <http://www.tldp.org/docs.html#howto>. Most people can
say N here.

Say Y here if you intend to attach this type of Token Ring PCMCIA
card to your computer. You then also need to say Y to "Token Ring

Warning: this driver will almost definitely fail if more than one
active Token Ring card is present.
