[PATCH RFC 0/8] xen/arm: initial cubieboard2 support.
See http://www.gossamer-threads.com/lists/xen/devel/297170 for some
information on how to get this going.
I''ve rebased and addressed the review comments.
As before several of the patches are not to be applied because they can
be done better using infrastructure from Julien''s "Allow Xen to boot
with a raw Device Tree" patch. They are included for completeness.

why dtrace is not quiet?
i''m running the following script:
#pragma D option quiet
profile:::tick-1sec
/ ++x >= 15 /
{
exit(0);
}
io:::start {
@io_size[execname] = sum(args[0]->b_bcount);
}
on exit, the script prints out the value of @io_size, why?
there''s no printa(), and i also specified "D option quiet" (i also tried -q).
this seems to happen with any kind of probe: on exit(0) all the associative arrays defined in the sc...

[PATCH] drm/nouveau: always do buffer object moves on bo->channel
- Use the "direct" objects that previously only the kernel fifo had.
- This avoids corruption on some buffer moves.

[PATCH v3 0/7] support for cubieboard2 / sunxi processors
See http://www.gossamer-threads.com/lists/xen/devel/297170 for some
information on how to get this going.
I''ve rebased and addressed the review comments.
With this rebase I''ve picked up some patches from Julien which were
required to do things properly, so the gic v7 and device blacklisting
patches have been changed to use the proper mechanisms.

How can I watch IO operations with dtrace on zfs?
I have been using iosoop script (see http://www.opensolaris.org/os/community/dtrace/scripts/) written by Brendan Gregg to look at the IO operations of my application. When I was running my test-program on a UFS filesystem I could see both read and write operations like:
UID PID D BLOCK SIZE COMM PATHNAME

ZFS, XFS, and EXT4 compared
I have a lot of people whispering "zfs" in my virtual ear these days,
and at the same time I have an irrational attachment to xfs based
entirely on its lack of the 32000 subdirectory limit. I''m not afraid of
ext4''s newness, since really a lot of that stuff has been in Lustre for
years. So a-benchmarking I went. Results at the bottom:

[PATCH 1/5] fs: allow short direct-io reads to be completed via buffered IO V2
V1->V2: Check to see if our current ppos is >= i_size after a short DIO read,
just in case it was actually a short read and we need to just return.
This is similar to what already happens in the write case. If we have a short
read while doing O_DIRECT, instead of just returning, fallthrough and try to
read the rest via buffered IO. BTRFS needs this because if we encounter a
compressed or
