Remove multi-descriptor support from legacy recieve path
Add memory usage efficiency by using more correct size descriptors for
small MTU sizes and optimize using LPE for <= 1522 byte frame sizes
An extra performance fix that effected our TCP window size growth
as a receiver. Set our initial buffer to be 128 bytes instead of 256
to prevent over-socket charge when truesize is computed in the stack.
old way: truesize = 256 + l1 = 256 + 1460 = 1716
new way: truesize = 128 + l1 = 128 + 1460 = 1588
The magic value that we can't cross is 1648.

Fixes for packet split related issues
* On platforms where PAGE_SIZE > 4K, driver will use only required number of
pages compared to always using 3 pages.
* Packet split won't be used if the PAGE_SIZE is > 16K
* Adds a statistics counter to splits.
* Setting the non Null ptr to zero sized buffers to solve packet split
receive descriptor error
* When the no of pages needed is calculated, the header buffer is not
included for a given MTU.

sys_reboot() now calls device_suspend(), so it is no longer necessary for
the e1000 driver to register a reboot notifier [in fact doing so results in
e1000_suspend() getting called twice].
(akpm: we need to fast-track this. It's causing ia64 to oops on shutdown)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
