The putback for

	PSARC/2008/376 PowerTOP for OpenSolaris
	6713863 integrate PowerTOP into Solaris

constitutes a flag day for all ON developers. You'll need to use
"nightly" to build and "bfu" to load the new archive.

This putback integrates the PowerTOP tool into ON. PowerTOP is an
observability tool that shows you how well the system is taking
advantage of the CPU's power management features and reports on the
activity that is causing the system to wake up and go to higher energy
consumption levels.

PowerTOP is a command line tool that is being delivered through a new
package, SUNWpowertop. Binaries will be installed under /usr/bin.

The tool uses DTrace sdt probes integrated into snv_82, so it requires
snv_82 or higher. Because it uses DTrace, a user must have DTrace
privileges (dtrace_user, dtrace_proc, dtrace_kernel) in order to run
PowerTOP.

We'd like to thank the following people who contributed to this putback:
Eric Saxe, Aubrey Li and Arjan van de Ven (from Intel), Chad Mynhier,
Penny Honda/Jeff Osteen (legal), Randy Fishel, Pat Bredenberg,
Konstantin Ananyev, Vinay Devadas (intern), Mark Haywood and to those
who I may have missed.

Thanks

Rafael
