Ingo Molnar 8446f1d391 [PATCH] detect soft lockups
This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP.

When enabled then per-CPU watchdog threads are started, which try to run
once per second.  If they get delayed for more than 10 seconds then a
callback from the timer interrupt detects this condition and prints out a
warning message and a stack dump (once per lockup incident).  The feature
is otherwise non-intrusive, it doesnt try to unlock the box in any way, it
only gets the debug info out, automatically, and on all CPUs affected by
the lockup.

Paolo 'Blaisorblade' Giarrusso 37fce857be [PATCH] uml: split CONFIG_FRAME_POINTER from DEBUG_INFO
Until now, FRAME_POINTER was set = DEBUG_INFO for UML.  Change it to be the
default way, so that it can be enabled alone (for instance to get better
backtraces on crashes).  The call-trace dumper which uses the frame pointer is
not yet in, I'm going to introduce it in a separate patch.

Matt Mackall c8538a7aa5 [PATCH] remove all kernel BUGs
This patch eliminates all kernel BUGs, trims about 35k off the typical
kernel, and makes the system slightly faster.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
