If you're sending the patches, this needs your signoff as well.

Also, it looks like these 5 all need to be applied as one, so can you
send a change log for the combined patch set saying what it is and what
it does (basically, what is the P3 and how does it differ from previous
stex models?)

Thanks,

James
