Having N different copies of the NixOS kernel configuration is bad
because these copies tend to diverge. For instance, our 3.10 config
lacked some modules that were enabled in older configs, probably
because the 3.10 config had been copied off an earlier version of some
older kernel config.
So now there is a single kernel config in common-config.nix. It has a
few conditionals to deal with new/removed kernel options, but
otherwise it's pretty straightforward.
Also, a lot of cut&paste boilerplate between the kernel Nix
expressions is gone (such as preConfigure).
This is for consistency with terminology in stdenv (and the terms
"hostDrv" and "buildDrv" are not very intuitive, even if they're
consistent with GNU terminology).
what the new nix thinks the fuloong is.
Anyone having the old nix should use a nixpkgs previous to this change to build
the new nix. And then, with the new nix, he can use any newer nixpkgs revision.

The "unset MODULE_DIR" trick was enough to get Linux 3.x kernels compiling, but it was definitely the Wrong Thing
We NEED MODULE_DIR set so that depmod can store the right dependencies during the build. The REAL problem with the
3.x kernels was two-fold: Our module-init-tools was so old that the kernel build needed to introduce a hack when
calling depmod (involving creating a symlink prepending 99.98 to the version number), and the depmod wrapper was
moved out of the Makefile into scripts/depmod.sh, so our substituteInPlace to get rid of '-b $(INSTALL_MOD_PATH)' in
the Makefile was a noop and INSTALL_MOD_PATH was still being passed to depmod. This is now fixed and modprobe can
successfully find dependencies using the modules.dep created during install

With the new kernel versioning scheme, the first release in a series only has a version number and
a major revision number (e.g. linux 3.0, linux 3.1-rc1, etc.). Unfortunately, the module
directory for these kernels still has a minor revision number (e.g. lib/modules/3.0.0, lib/modules/3.0.1-rc1, etc.).
This causes problems for packages such as broadcom_sta that need to know the module directory, so
this attribute will allow setting the module directory version number separate from the
kernel version number when necessary.

Moved the hardcoded postBuild hook from the builder to generic.nix:
Some old kernel (such as 2.6.15) did not yet support the unifdef target.
As a result, compiling them with the current Linux builder leads to a
failure.
Fixed by moving this hook as argument of the top-level function of
generic.nix. This allows some kernel nix codes to overrides its default
value.

I fixed conflicts regarding the renaming 'kernel' -> 'linux' in all-packages.
Also a small conflict in all-packages about making openssl overridable.
And I some linux 2.6.31-zen kernel files also marked in conflict.

I still have not added anything in the kernels about cross compilation.
I moved the platform definitions out of all-packages.
I have not written good platform definitions for the sheevaplug - only for the
PC.
Only the linux-2.6.32 expression uses the platforms kernelConfig.
The linux-2.6.31 was broken, and I left it broken.

`generate-config.pl' runs `make config' to generate a Linux kernel
configuration file. For each question (i.e. kernel configuration
option), unless an override is provided, it answers "m" if possible,
and otherwise uses the default answer (as determined by the default
config for the architecture). This is safer than allmodconfig,
which answers "y" everywhere it can't answer "m" and thus ends up
enabling a lot of experimental or debug options. (For this reason,
a configuration generated by allmodconfig must be carefully checked
with every new release to ensure that nothing dangerous is enabled.
The default config should be safer wrt new kernel releases.)
Overrides are specified in the `config' argument to generic.nix,
which is a string that contains lines such as `EXT2_FS_POSIX_ACL y'.
The script warns about ignored options, and aborts if `make config'
selects an answer inconsistent with the one in `config'. This
allows us to be sure that `make config' doesn't silently override
our configuration values (e.g., depending on other options, it will
set FB_TILEBLITTING to "y" even if we want it to be "n").

This comes from:
svn diff ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.
trunk@18255 comes from the last time I updated stdenv-updates from trunk.
