I focused on patches 2, 3 & 5, seems like you have good feedback on
the others by more qualified folks than me.
At a high level I don't have any major issues with the set. There are
some rough edges that I noticed as I was reading it (as would any
patch of this size), but I think it's probably not a good use of
either of our time for me to nitpick 10k lines of code over multiple
iterations.
So in the interest of not letting the perfect get in the way of the
good, I suggest we apply the set and fix up as time and necessity
allow.
Patches 2/3/5 are:
