The tracepoint sample code was used to teach developers how to
create their own tracepoints. But now the trace_events have been
added as a higher level that is used directly by developers today.Only the trace_event code should use the tracepoint interface
directly and no new tracepoints should be added.Besides, the example had a race condition with the use of the
->d_name.name dentry field, as pointed out by Al Viro.Best just to remove the code so it wont be used by other developers.

Add an rpmsg driver sample, which demonstrates how to communicate with
an AMP-configured remote processor over the rpmsg bus.Note how once probed, the driver can immediately start sending messages
using the rpmsg_send() API, without having to worry about creating endpoints
or allocating rpmsg addresses: all that work is done by the rpmsg bus,
and the required information is already embedded in the rpmsg channel
that the driver is probed with.In this sample, the driver simply sends a "Hello World!" message to the remote
processor repeatedly.Designed with Brian Swetland .

samples/hid-example.o needs some Kconfig and Makefile additions in order
to build. It should use headers from the build tree, so use
HEADERS_CHECK to require that those header files be present.Change the kconfig symbol from tristate to bool since userspace cannot be
built as loadable modules.However, I don't understand why the userspace header files are not present
as reported in Andrew's build log, since it builds OK on x86_64 without
any of these changes.Signed-off-by: Randy Dunlap

Move kprobes examples from Documentation/kprobes.txt to under samples/.
Patch originally by Randy Dunlap.o Updated the patch to apply on 2.6.25-rc3
o Modified examples code to build on multiple architectures. Currently,
the kprobe and jprobe examples code works for x86 and powerpc
o Cleaned up unneeded #includes
o Cleaned up Kconfig per Sam Ravnborg's suggestions to fix build break
on archs that don't have kretprobes
o Implemented suggestions by Mathieu Desnoyers on CONFIG_KRETPROBES
o Included Andrew Morton's cleanup based on x86-git
o Modified kretprobe_example to act as a arch-agnostic module to
determine routine execution times:
Use 'modprobe kretprobe_example func=' to determine
execution time of func_name in nanoseconds.Signed-off-by: Randy Dunlap
