In particular, CONFIG_TIGON3 newly depends on
CONFIG_NET_VENDOR_BROADCOM which will no be selected when doing a
"make oldconfig" from a working config.

When you type "make oldconfig" with an existing .config it prompts you
for those vendor guards, giving you ample opportunity to say yes to
them.

Which is a bit of a pain for automated systems.  Ours does (essentially):

yes '' | make oldconfig

We really don't want to select every new config item that comes along.

So, Mikey did a test for me (he was bitten by this today).  Just one of
the powerpc configs (pseries_defconfig which should, in theory, build a
kernel that will boot on almost all our POWER server machines) loses all
these drivers if you do a "make pseries_defconfig":

 -CONFIG_IBMVETH=y
 -CONFIG_PCNET32=y
 -CONFIG_E100=y
 -CONFIG_ACENIC=m
 -CONFIG_ACENIC_OMIT_TIGON_I=y
 -CONFIG_E1000=y
 -CONFIG_E1000E=y
 -CONFIG_BNX2=m
 -CONFIG_CHELSIO_T3=m
 -CONFIG_CHELSIO_T4=m
 -CONFIG_IXGBE=m
 -CONFIG_IXGB=m
 -CONFIG_S2IO=m
 -CONFIG_MYRI10GE=m
 -CONFIG_NETXEN_NIC=m
 -CONFIG_QLGE=m
 -CONFIG_BE2NET=m

That is just one of our deconfigs ... there are over 400 defconfigs in
the kernel and a lot of them will need to be updated.

Mikey asks:  Will Dave take these updates if we get Acks from the
maintainers?  :-)
