ETA on HPS USB stack into CURRENT?

[Anish Mistry]

	What requirements still need to be met before the HPS USB stack is 
committed to CURRENT?  I understand that introducing a major 
sub-system change so close the start of a release cycle can be very 
disruptive.  My main concern is that the RELENG_7 branch will be 
arriving in the next couple months and imp@ mentioned in the (Re: 
UMASS pbm at startup) thread that RELENG_7 might not see the new 
stack.  This means that we'll have to wait until an 8.x release 
(2009?) until we see the new stack in a stock install.  Also the 
current stack will then need to be supported during the entire life 
of RELENG_7 which will probably into at least late 2010.
	From here on out the limitations of the current USB stack not being 
MPSAFE will only become more apparent with more systems shipping with 
multiple processors.  Such as not allow CPUs to drop to C3 when USB 
is loaded, performance issues, and various HID parsing problems.
	With all that said what would be needed so that we could see the new 
stack in 7.1 eventhough 7.0 would have the old stack?  Though this 
does seem to be asking for a lot of trouble since it would be a 
STABLE branch.
