These patches provide a kernel tracing interface called "trace".
(update) Updated documentation and added configuration dependency
on KPROBES for trace sample code.
The motivation for "trace" is to:
- Provide a simple set of tracing primitives that will utilize the high-
performance and low-overhead of relayfs for passing traces data from
kernel to user space.
- Provide a common user interface for managing kernel traces.
- Allow for binary as well as ascii trace data.
- Incorporate features from the systemtap runtime that are
useful to others.
Patches are against 2.6.23-rc8-mm2

Note: Patch 2/3 provides a service used by patch 1/3
thus must be applied first or at the same time.
Note: The following patches must be applied prior to 3/3.
