Not that I know of.  As everyone is aware, patches need to be in my
patch system if they want me to apply them - which would've been
especially important as I was away from kernel stuff for a week at
the start of March (for medical reasons) and I can't be expected to
track the status of stuff which is buried behind 1000+ extra mails.

In any case, I'm currently not accepting /any/ patches into my tree at
present; I'm chasing a horrid instability on one of my test platforms
which is making it impossible to tell whether any particular change or
changes in my tree is responsible or not for it.  It doesn't seem to be
a hardware failure (if it was, I'd simply take the board out of the
nightly test system.)

It's quite literally taking hours to figure out what's going on - I've
been on this for about 12 hours now and still not much closer to knowing
what's causing it (other than I know that -rc1 plus my queue seems to be
fine, -rc3 plus my queue is definitely broken, -rc3 alone is fine.  So
something I'm already carrying seems to be responsible, but each time I
identify a particular patch and drop _just_ that change, I find that the
problem is back when I try my queue minus the bad changes.  With a test
cycle time of 20+ minutes (due to the number of boots required to make
certain of a dependable result), this is /really/ slow progress.

Right now, I can't be positively sure that /anything/ I have already
merged isn't a factor in causing this problem, so I don't want to
augment my tree with any additional patches which would upset my
ability to move about in the tree, and get reproducable results from
repeated testing.  To merge something else will probably mean I'll
have to start again from the beginning and the last 12 hours spent
testing will have been wasted.

Sorry.
