2.6.1-tiny1 tree for small systems

2.6.1-tiny1 tree for small systems

[Matt Mackall]

This is the latest release of the -tiny kernel tree. The aim of this
tree is to collect patches that reduce kernel disk and memory
footprint as well as tools for working on small systems. Target users
are things like embedded systems, small or legacy desktop folks, and
handhelds.

Latest release includes:
 - update to 2.6.1
 - add latest netdrvr patchkit (Jeff Garzik)
 - various compile fixes for last release
 - various tweaks to netpoll, netconsole, and kgdb-over-ethernet
 - laptop mode (Bart Samwel via -mm)
 - optional block device layer (Eric Biederman)
 - optional simple boot flag (Zwane Mwaikambo)
 - optional ksyms (Zwane Mwaikambo)
 - optional PCI quirk detection (Zwane Mwaikambo)
 - free early bootstrap code (Zwane Mwaikambo)
 - optional direct IO support
 - optional minimal lockless mempool
 - minor cleanups

Here's a test boot of my development config (console, ide, ext2, and
ipv4) with mem=2m, which is actually only 1664k after accounting for
BIOS memory hole:

Uncompressing Linux... Ok, booting the kernel.

Good catch.  I can't account for it all.  But half of it is that
/proc does not compile out it's block device reporting when CONFIG_BLOCK
is disabled.  Which accounts for:

Which still leaves:

That one pops up if you don't have CPU support for Intel which, at least according to the menus, seems like a valid configuration.

That should be fixed in latest -tiny as well as some of the proc
stuff.
