Hi,

Been bugging me that I didn't like the v2 of the "improve the usercopy
for sendmsg/recvmsg" patch, so I re-did patch 1 here so that I could
do a prep patch (patch 2), and finally re-do the usercopy improvement
on top of that. Passes my testing, win is actually slightly larger
with this change (closer to 10%, so at least it didn't regress.
