[PATCH 0/3] A kernel tracing interface

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

Summary of patches:
[patch 1/3]  Trace code and documentation
[patch 2/3]  Relay Reset Consumed
[patch 3/3]  Trace sample

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.
[patch 3/5] Add samples subdir

[patch 4/5] Linux Kernel Markers - Samples
