Hi Linus,
I would like to ask for pulling a set of fixup patches for ARM
dma-mapping extensions merged in v3.6-rc1.
The following changes since commit 0d7614f09c1ebdbaa1599a5aba7593f147bf96ee:
Linux 3.6-rc1 (2012-08-02 16:38:10 -0700)
with the top-most commit
Do not leak memory by updating pointer with potentially NULL realloc return
value.
Found by Linux Driver Verification project (linuxtesting.org).

Hi,
Yes it used to work with 2.6 kernel.
Ok I will do a bisect and try to find the source of the problem.
I'll notify you if I'll find something but don't expect it to be fast
cause the problem happens on my home laptop (pretty old and rusty :) )
and I also have a lot of other stuff to do.

Hi all,
Now, We have node masks for both N_NORMAL_MEMORY and
N_HIGH_MEMORY to distinguish between normal and highmem on platforms such as
x86.
But we still don't have such a mechanism to distinguish between "normal" and
"movable"
memory.

NFS appears to use d_obtain_alias() to create the root dentry rather
than d_make_root. This can cause 'prepend_path()' to complain that the
root has a weird name if an NFS filesystem is lazily unmounted.
e.g. if "/mnt" is an NFS mount then
{ cd /mnt; umount -l /mnt ; ls -l /proc/self/cwd; }
This patchset updates arch-vt8500 to devicetree and removes all the old-style
code. Support for WM8650 has also been added.
Example dts/dtsi files are given for the three currently supported models.
Major changes:
GPIO code has been converted to a platform_device and rewritten as WM8505

Hi Boaz,
Today's linux-next merge of the osd tree got a conflict in
fs/nfs/nfs4proc.c between commit 47fbf7976e0b ("NFSv4.1: Remove a bogus
BUG_ON() in nfs4_layoutreturn_done") from the nfs tree and commit
d8e8b68405db ("pnfs: Don't BUG on info received from Server") from the
osd tree.

This is changing the semantics of the clone. Sorry, I missed this

I think it would be better to introduce bio_clone*() functions in a
separate patch and convert the users in a different one.

This patch is exporting the rproc_report_crash function which can be used
to report a rproc crash to the remoteproc core. This function is specially
thought to be called by low-level remoteproc driver code in case of
detecting a crash (remoteproc is not functional anymore). Using this
function
This patch is introducing rproc_trigger_recover function which is in
charge of recovering the rproc. One way to recover the rproc after a crash
is resetting all its virtio devices. Doing that, all rpmsg drivers are
restored along with the rpmsg devices and that also causes the reset of
the

Add a debugfs entry (named recovery) so that recovery can be disabled
dynamically at runtime. This entry is very useful when you are trying to
debug a rproc crash. Without this a recovery will take place making
impossible to debug the issue.

These set of patches make possible the remoteproc recover after a crash.
This is a hard recovery, that means the remoteproc is reset and it will
start from the beginning. When a crash happen all the virtio devices are
destroyed. Therefore, both rpmsg drivers and devices are gracefully
removed
