You get a gold star!

Somewhere in between 3.3.x and 3.7.x I managed to lose PIMV1 and PIMV2
support
in the kernel configuration, and also lost the NO_HZ and faster clock I'd
had there too.

CONFIG_NO_HZ=y
CONFIG_HZ=256
CONFIG_HZ_256=y

As well as the other TCP variants like VENO and LP (I think, I might have
added them elsewhere)

Checking into that latter bit as well as into the unaligned traps tonight
(unless someone beats me to it)
