ext3_msg() takes the printk prefix as the second parameter and the
format string as the third parameter. Two callers of ext3_msg omit the
prefix and pass the format string as the second parameter and the first
parameter to the format string as the third parameter. In both cases
this string comes from an arbitrary source. Which means the string may
contain format string characters, which will
lead to undefined and potentially harmful behavior.
The issue was introduced in commit 4cf46b67eb("ext3: Unify log messages
in ext3") and is fixed by this patch.

The bulk of __dquot_initialize runs under the dqptr_sem which
protects the inode->i_dquot pointers. It doesn't protect the
dereferenced contents, though. Those are protected by the
dq_data_lock, which is missing around the dquot_resv_space call.

When building a multiplatform kernel, we could end up with a smaller
number of GPIOs than the one required by the platform the kernel was
running on.
Sort the max GPIO number by descending order so that we always take the
highest number required.

Rob Herring has observed that c81611c4e96f "xen: event channel arrays are
xen_ulong_t and not unsigned long" introduced a compile failure when building
without CONFIG_AEABI:
/tmp/ccJaIZOW.s: Assembler messages:
/tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]'
Will Deacon pointed out that this is because OABI does not require even base
registers for 64-bit values. We can avoid this by simply using the existing
atomic64_xchg operation and the same containerof trick as used by the cmpxchg
macros. However since this code is used on memory which is shared with the
hypervisor we require proper atomic instructions and cannot use the generic
atomic64 callbacks (which are based on spinlocks), therefore add a dependency
on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much
downside to this.
While thinking about this we also observed that OABI has different struct
alignment requirements to EABI, which is a problem for hypercall argument
structs which are shared with the hypervisor and which must be in EABI layout.
Since I don't expect people to want to run OABI kernels on Xen depend on
CONFIG_AEABI explicitly too (although it also happens to be enforced by the
!GENERIC_ATOMIC64 requirement too).

As pointed out by Dan Carpenper in
<http://driverdev.linuxdriverproject.org/pipermail/devel/2013-February/036025.html>,
the dt9812 comedi driver's use of the `chanspec` member of `struct
comedi_insn` as a channel number is incorrect. Change it to use
`CR_CHAN(insn->chanspec)` as the channel number (where `insn` is a
pointer to the `struct comedi_insn` being processed).

added at this time, the call to imx_drm_handle_vblank will result in

usb: fixes for v3.9-rc3
Most fixes are on 'musb' driver. There's a sparse warning
fix which marks omap2430_glue as static, a build warning
fix which was found with randconfig, a fix for omap_musb_mailbox
check and removal of 'select' from musb's Kconfig to prevent
Kconfig warnings.
Other than that, pxa25x got a fix which was introduced by the
latest conversion to udc_start/udc_stop patchset, kernel-doc

git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
Regression fixes and oops fixes for nouveau.
* 'drm-nouveau-fixes-3.9' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nv50: use correct tiling methods for m2mf buffer moves
drm/nouveau: idle channel before releasing notify object
drm/nouveau: fix regression in vblanking
drm/nv50: encoder creation failure doesn't mean full init failure

We always boot from PLL1, so let's have pll1_sys in the clks_init_on
list to have clk prepare/enable use count match the hardware status,
so that drivers managing pll1_sys like cpufreq can get the use count
right from the start.

When it uses regulators the mms114 driver checks to see if it managed to
acquire regulators and ignores errors. This is not the intended usage and
not great style in general.
Since the driver already refuses to probe if it fails to allocate the
regulators simply make the enable and disable calls unconditional and
add appropriate error handling, including adding cleanup of the
regulators if setup_reg() fails.

The keymap size used by tc3589x is too low, leading to the driver
overwriting other people's memory. Fix this by making the driver
use the automatically allocated keymap provided by
matrix_keypad_build_keymap() instead of allocating one on its own.

Unmapping it while it's still in use (e.g. by M2MF) can lead to page faults
and a lot of TRAP_M2MF spam in dmesg.

nv50_vblank_enable/disable got switched from NV50_PDISPLAY_INTR_EN_1_VBLANK_CRTC_0 (4) << head to 1 << head, which is wrong.
4 << head is the correct value.

The dcb netlink interface leaks stack memory in various places:
* perm_addr[] buffer is only filled at max with 12 of the 32 bytes but
copied completely,
* no in-kernel driver fills all fields of an IEEE 802.1Qaz subcommand,
so we're leaking up to 58 bytes for ieee_ets structs, up to 136 bytes
for ieee_pfc structs, etc.,
* the same is true for CEE -- no in-kernel driver fills the whole
struct,
Prevent all of the above stack info leaks by properly initializing the
buffers/structures involved.

Initialize the mac address buffer with 0 as the driver specific function
will probably not fill the whole buffer. In fact, all in-kernel drivers
fill only ETH_ALEN of the MAX_ADDR_LEN bytes, i.e. 6 of the 32 possible
bytes. Therefore we currently leak 26 bytes of stack memory to userland
via the netlink interface.
