The functions used for working with ceph page vectors are defined
with char pointers, but they're really intended to operate on
untyped data. Change the types of these function parameters
to (void *) to reflect this.
(Note that the functions now assume void pointer arithmetic works
like arithmetic on char pointers.)

Please pull mpc5xxx patches for v3.9. The bestcomm driver is
moved to drivers/dma (so it will be usable for ColdFire).
mpc5121 now provides common dtsi file and existing mpc5121 device
trees use it. There are some minor clock init and sparse fixes
and updates for various 5200 device tree files from Grant. Some
fixes for bugs in the mpc5121 DIU driver are also included here
(Andrew Morton suggested to push them via my mpc5xxx tree).

Replace llist_for_each_entry_safe with a while loop.
llist_for_each_entry_safe can trigger a bug in GCC 4.1, so it's best
to remove it and use a while loop and do the deletion manually.
Specifically this bug can be triggered by hot-unplugging a disk, either
by doing xm block-detach or by save/restore cycle.
BUG: unable to handle kernel paging request at fffffffffffffff0
IP: [<ffffffffa0047223>] blkif_free+0x63/0x130 [xen_blkfront]
The crash call trace is:

When drilling down to the assembler code, on newer GCC it does
.L29:
cmpq $-16, %r12 #, persistent_gnt check
je .L30 #, out of the loop
.L25:
... code in the loop
testq %r13, %r13 # n
je .L29 #, back to the top of the loop
cmpq $-16, %r12 #, persistent_gnt check
movq 16(%r12), %r13 # <variable>.node.next, n
jne .L25 #, back to the top of the loop
.L30:
While on GCC 4.1, it is:
L78:
... code in the loop
testq %r13, %r13 # n
je .L78 #, back to the top of the loop
movq 16(%rbx), %r13 # <variable>.node.next, n
jmp .L78 #, back to the top of the loop
Which basically means that the exit loop condition instead of
being:
&(pos)->member != NULL;
is:
;
which makes the loop unbound.
Since xen-blkfront is the only user of the llist_for_each_entry_safe
macro remove it from llist.h.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
These changes contain the OMAP USB related platform data changes
that were dropped from linux next because of the merge conflicts
as requested by me and Olof. The reason was that at this point
we really should be able to do the arch/arm related changes
separately from driver changes to avoid dependencies between
branches.
These patches were initially part of the USB related MFD patches.
Based on our comments, Roger Quadros quickly reworked these
patches into a shared branch between ARM SoC tree and the MFD
tree, then separate patches for the OMAP platform data and
MFD driver.
Note that this branch will conflict with c1d1cd597fc7
("ARM: OMAP2+: omap_device: remove obsolete pm_lats and
early_device code"). Please see http://lkml.org/lkml/2013/2/11/16

fs/nfsd/nfs4state.c: In function ‘free_client’:

The cause of that warning is that lockdep_assert_held() compiles

the argument to lockdep_assert_held() as a nop if CONFIG_LOCKDEP

Connection tracking helpers have to drop packets under exceptional
situations. Currently, the user gets the following logging message
in case that happens:
nf_ct_%s: dropping packet ...
However, depending on the helper, there are different reasons why a
packet can be dropped.
This patch modifies the existing code to provide more specific
error message in the scope of each helper to help users to debug
the reason why the packet has been dropped, ie:
nf_ct_%s: dropping packet: reason ...

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
This probably is the last big pull request for wireless bits
for 3.9. Of course, I'm sure there will be a few stragglers here
and there...surely a few bug fixes as well... :-) (In fact, I see
that Johannes has already queued-up a few more for me while I was
preparing this...)
Included are a number of pulls...
For mac80211-next, Johannes says:
"The biggest change I have is undoubtedly Marco's mesh powersave
implementation. Beyond that, I have a patch from Emmanuel to modify the
DTIM period API in mac80211, scan improvements and a removal of some
previous workaround code from Stanislaw, dynamic short slot time from
Thomas and 64-bit station byte counters from Vladimir. I also made a
number of changes myself, some related to WoWLAN, some auth/deauth
improvements and most of them BSS list cleanups."
"This time, I have relatively large number of fixes in various areas of
the code (a memory leak in regulatory, an RX race in mac80211, the new
radar checking caused a P2P device problem, some mesh issues with
stations, an older bug in tracing and for kernel-doc) as well as a
number of small new features. The biggest (in the diffstat) is my work
on hidden SSID tracking."
"Please pull to get
* radar detection work from Simon
* mesh improvements from Thomas
* a connection monitoring/powersave fix from Wojciech
* TDLS-related station management work from Jouni
* VLAN crypto fixes from Michael Braun
* CCK support in minstrel_ht from Felix
* an SMPS (not SMSP, oops) related improvement in mac80211 (Emmanuel)
* some WoWLAN work from Amitkumar Karwar: pattern match offset and a
documentation fix
* some WoWLAN work from myself (TCP connection wakeup feature API)
* and a lot of VHT (and some HT) work (also from myself)
And a number of more random cleanups/fixes. I merged mac80211/master to
avoid a merge problem there."
And regarding iwlwifi-next, Johannes says:
"We continue work on our new driver, but I also have a WoWLAN and AP mode
improvement for the previous driver and a change to use threaded
interrupts to prepare us for working with non-PCIe devices."
Regarding wl12xx, Luca says:
"A few more patches intended for 3.9. Mostly some clean-ups I've been
doing to make it easier to support device-tree. Also including one bug
fix for wl12xx where the rates we advertise were wrong and an update in
the wlconf structure to support newer firmwares."
For the nfc-next bits, Samuel says:
"This is the second NFC pull request for 3.9.
We have:
- A few pn533 fixes on top of Waldemar refactorization of the driver, one of
them fixes target mode.
- A new driver for Inside Secure microread chipset. It supports two
physical layers: i2c and MEI. The MEI one depends on a patchset that's
been sent to Greg Kroah-Hartman for inclusion into the 3.9 kernel [1]. The
dependency is a KConfig one which means this code is not buildable as long
as the MEI API is not usptream."
"This 3rd NFC pull request for 3.9 contains a fix for the microread MEI
physical layer support, as the MEI bus API changed.
From the MEI code, we now pass the MEI id back to the driver probe routine,
and we also pass a name and a MEI id table through the mei_bus_driver
structure. A few renames as well like e.g. mei_bus_driver to mei_driver or
mei_bus_client to mei_device in order to be closer to the driver model
practices."
For the ath6kl bits, Kalle says:
"There's not anything special here, most of the patches are just code
cleanup. The only functional changes are using the beacon interval from user
space and fixing a crash which happens when inserting and removing the
module in a loop."
Also, I pulled the wireless tree in order to resolve some pending
merge issues. On top of that, there is a bunch of work on brcmfmac
that leads up to P2P support. Also, mwifiex, rtlwifi, and a variety
of other drivers see some basic cleanups and minor enhancements.
Please let me know if there are problems!

Update most of "include/linux/ceph/rados.h" to match its user space

- ceph_osd_op_mode_read() and ceph_osd_op_mode_modify() are

- CEPH_OSD_FLAG_PEERSTAT is now CEPH_OSD_FLAG_PEERSTAT_OLD, but
that was never used in the kernel

Although extent status is loaded on-demand, we also need to reclaim
extent from the tree when we are under a heavy memory pressure because
in some cases fragmented extent tree causes status tree costs too much
memory.
Here we maintain a lru list in super_block. When the extent status of
an inode is accessed and changed, this inode will be move to the tail
of the list. The inode will be dropped from this list when it is
cleared. In the inode, a counter is added to count the number of
cached objects in extent status tree. Here only written/unwritten/hole
extent is counted because delayed extent doesn't be reclaimed due to
fiemap, bigalloc and seek_data/hole need it. The counter will be
increased as a new extent is allocated, and it will be decreased as a
extent is freed.
In this commit we use normal shrinker framework to reclaim memory from
the status tree. ext4_es_reclaim_extents_count() traverses the lru list
to count the number of reclaimable extents. ext4_es_shrink() tries to
reclaim written/unwritten/hole extents from extent status tree. The
inode that has been shrunk is moved to the tail of lru list.

After tracking all extent status, we already have a extent cache in
memory. Every time we want to lookup a block mapping, we can first
try to lookup it in extent status tree to avoid a potential disk I/O.
A new function called ext4_es_lookup_extent is defined to finish this
work. When we try to lookup a block mapping, we always call
ext4_map_blocks and/or ext4_da_map_blocks. So in these functions we
first try to lookup a block mapping in extent status tree.
A new flag EXT4_GET_BLOCKS_NO_PUT_HOLE is used in ext4_da_map_blocks
in order not to put a hole into extent status tree because this hole
will be converted to delayed extent in the tree immediately.

This commit adds two members in extent_status structure to let it record
physical block and extent status. Here es_pblk is used to record both
of them because physical block only has 48 bits. So extent status could

unwritten, delayed and hole are defined as status.
Due to new member is added into extent status tree, all interfaces need

pm_idle appears in no generic Linux code,
it appears only in architecture-specific code.
Thus, pm_idle should not be declared in pm.h.
Architectures that use an idle function pointer
should delcare one local to their architecture,
and/or use cpuidle.

Simplify life for drivers using an encoder-slave, so that they can make
their drm_encoder_helper_funcs const, rather than needing to dynamically
allocate and populate them.

Add helper to display fb's which can be used directly in drm_info_list:
static struct drm_info_list foo_debugfs_list[] = {
...
{ "fb", drm_fb_cma_debugfs_show, 0 },
};
to display information about CMA fb objects, as well as a
drm_gem_cma_describe() which can be used if the driver bothers to keep
a list of CMA GEM objects.

Now that the omapdss interface has been reworked so that omapdrm can use
dispc directly, we have been able to fix the remaining functional kms
issues with omapdrm. And in the mean time the PM sequencing and many
other of that open issues have been solved. So I think it makes sense
to finally move omapdrm out of staging.
