Shea Levy 4fa4ab3a6e Partially revert my recent kernelPackages changes
First, pass in `self' again so that overriding works properly (thanks
for pointing that out, @edolstra)

Second, instead of having linuxPackages*.kernel mean something different
inside the set and out, add a new attribute linuxPackages*.kernelDev,
which for the generic kernel is simply linuxPackages*.kernel but for the
manual-config kernel is the `dev' output (which has the build tree,
source tree, etc.)

The second change required trivial modifications in a bunch of
expressions, I verified that all of the linuxPackages* sets defined in
all-packages.nix have the same drv paths before and after the change.

Exmap is a utility which takes a snapshot of how the physical
memory and swap space are currently used by all the processes on
your system. It examines which page of memory are shared between
which processes, so that it can share the cost of the pages
fairly when calculating usage totals.
