SCM_SCREDENTIALS should apply to write() syscalls only either source or destination
socket asserted SOCK_PASSCRED. The original implememtation in maybe_add_creds is wrong,
and breaks several LSB testcases ( i.e. /tset/LSB.os/netowkr/recvfrom/T.recvfrom).

Johan's 'fix use-after-free in TIOCMIWAIT' patchset[1] introduces
one bug which can cause kernel hang when opening port.
This patch initialized the 'port->delta_msr_wait' waitqueue head
to fix the bug which is introduced in 3.9-rc4.

Jeff Kirsher says:
====================
This series contains updates to ixgbevf and igb.
The ixgbevf calls to pci_disable_msix() and to free the msix_entries
memory should not occur if device open fails. Instead they should be
called during device driver removal to balance with the call to
pci_enable_msix() and the call to allocate msix_entries memory
during the device probe and driver load.
The remaining 4 of 5 igb patches are simple 1-3 line patches to fix
several issues such as possible null pointer dereference, PHC stopping
on max frequency, make sensor info static and SR-IOV initialization
reordering.
The remaining igb patch to fix anti-spoofing config fixes a problem
in i350 where anti spoofing configuration was written into a wrong
register.

skb->ip_summed should be CHECKSUM_UNNECESSARY when the driver reports that
checksums were correct and CHECKSUM_NONE in any other case. They're
currently placed vice versa, which breaks the forwarding scenario. Fix it
by placing them as described above.

Running HPDET while the headphone outputs are enabled can disrupt the
operation of HPDET. In order to avoid this HPDET needs to disable the
headphone outputs and ASoC needs to not enable them while HPDET is
running.
For extcon instead of checking if the headphone output is enabled when
doing magic application unconditionally disable the output and restore
the state which ASoC wants set when undoing the magic.

Do the ASoC side of this by storing the enable state in the core driver
structure and only writing to the device if a flag indicating that the
accessory detection side is in a state where it can have the headphone
output stage enabled.

Currently the mxs_dma_data struct, which gets passed to the dmaengine driver, is
allocated in the pcm driver's open callback. The mxs_dma_data struct has exactly
one field which is initialized from the the same field in the mxs_pcm_dma_params
struct. The mxs_pcm_dma_params struct gets passed to the pcm driver from the dai
driver. Instead of taking this indirection embed the mxs_dma_data struct
directly in the mxs_pcm_dma_params struct. This allows us to simplify the pcm
driver quite a bit, since we don't have to care about memory managing the
mxs_dma_data struct anymore.

Currently the ep93xx_dma_params struct which is passed to the dmaengine driver
is constructed at runtime from the ep93xx_pcm_dma_params that gets passed to the
ep93xx PCM driver from one of the ep93xx DAI drivers. The ep93xx_pcm_dma_params
struct is almost identical to the ep93xx_dma_params struct. The only missing
field is the 'direction' field, which is computed at runtime in the PCM driver
based on the current substream. Since we know in advance which
ep93xx_pcm_dma_params struct is being used for which substream at compile time,
we also already know which direction to use at compile time. So we can easily
replace all instances of ep93xx_pcm_dma_params with their ep93xx_dma_params
counterpart. This allows us to simplify the code in the ep93xx pcm driver quite
a bit.

The omap PCM driver provides a set_threshold callback which gets called by the
PCM driver when either playback or capture is started. The only DAI driver which
sets this callback is the mcbsp driver. This patch removes the callback from the
PCM driver and moves the invocation of the omap_mcbsp_set_threshold() function
to the mcbsp hw_params callback since this is the only place where the threshold
size can change. Doing so allows us to use the default dmaengine PCM trigger
callback in the omap PCM driver.

There is a sync issue with hotplug operation. It's possible that when
imx_cpu_kill gets running on primary core, the imx_cpu_die execution
on the core which is to be killed hasn't been finished yet. The problem
will very likely be hit when running suspend without no_console_suspend
setting on kernel cmdline.
It uses cpu jumping argument register to sync imx_cpu_die and
imx_cpu_kill. The register will be set in imx_cpu_die and imx_cpu_kill
will wait for the register being cleared to actually kill the cpu.

Since commit a1fd287780c8e91fed4957b30c757b0c93021162:
"[media] bttv-driver: fix two warnings"
cropcap.defrect.height and cropcap.bounds.height for the PAL entry are 32
resp 30 pixels too large, if a userspace app (ie xawtv) actually tries to use
the full advertised height, the resulting image is broken in ways only a
screenshot can describe.
The cause of this is the fix for this warning:
drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init]
In this chunk of the commit:
@@ -301,11 +301,10 @@ const struct bttv_tvnorm bttv_tvnorms[] = {
/* totalwidth */ 1135,
/* sqwidth */ 944,
/* vdelay */ 0x20,
- /* sheight */ 576,
- /* videostart0 */ 23)
/* bt878 (and bt848?) can capture another
line below active video. */
- .cropcap.bounds.height = (576 + 2) + 0x20 - 2,
+ /* sheight */ (576 + 2) + 0x20 - 2,
+ /* videostart0 */ 23)
},{
.v4l2_id = V4L2_STD_NTSC_M | V4L2_STD_NTSC_M_KR,
.name = "NTSC",
Which replaces the overriding of cropcap.bounds.height initialization outside
of the CROPCAP macro (which also initializes it), with passing a
different sheight value to the CROPCAP macro.
There are 2 problems with this warning fix:
1) The sheight value is used twice in the CROPCAP macro, and the old code
only changed one resulting value.
2) The old code increased the .cropcap.bounds.height value (and did not
touch the .cropcap.defrect.height value at all) by 2, where as the fixed
code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2
to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so
now is done twice for .cropcap.bounds.height, and also is applied to
.cropcap.defrect.height where it should not be applied at all.
This patch fixes this by adding an extraheight parameter to the CROPCAP entry
and using it for the PAL entry.

When a multi-threaded init exits and the initial thread is not the
last thread to exit the initial thread hangs around as a zombie
until the last thread exits. In that case zap_pid_ns_processes
needs to wait until there are only 2 hashed pids in the pid
namespace not one.

For 82576 MAC type, max_adj is reported as 1000000000 ppb. However, if
this value is passed to igb_ptp_adjfreq_82576, incvalue overflows out of
INCVALUE_82576_MASK, resulting in setting of zero TIMINCA.incvalue, stopping
the PHC (instead of going at twice the nominal speed).
Fix the advertised max_adj value to the largest value hardware can handle.
As there is no min_adj value available (-max_adj is used instead), this will
also prevent stopping the clock intentionally. It's probably not a big deal,
other igb MAC types don't support stopping the clock, either.

The max_vfs= option has always been self limiting to the number of VFs
supported by the device. fa44f2f1 added SR-IOV configuration via
sysfs, but in the process broke this self correction factor. The
failing path is:
igb_probe
igb_sw_init
if (max_vfs > 7) {
adapter->vfs_allocated_count = 7;
...
igb_probe_vfs
igb_enable_sriov(, max_vfs)
if (num_vfs > 7) {
err = -EPERM;
...
This leaves vfs_allocated_count = 7 and vf_data = NULL, so we bomb out
when igb_probe finally calls igb_reset. It seems like a really bad
idea, and somewhat pointless, to set vfs_allocated_count separate from
vf_data, but limiting max_vfs is enough to avoid the null pointer.

The setup code in proc-arm740.S is completely broken and, as far as I
can tell, always has been. I was >this< close to ripping it out, when a
740t core-tile materialised in the office, so I've had a crack at fixing
things up:
- Fix the ram/flash area calculations so that we actually set
the condition flags before testing them...
- Fix the proc_info structure so that __cpu_io_mmu_flags are
defined as 0, placing the __cpu_flush pointer at the correct
offset
- Re-number the registers used during __arm740_setup so that
we don't clobber the machine ID et al
- Advertise Thumb support via the hwcaps, since 740T is the only

This is only used by 740t, which is a v4 core and (by my reading of the

making the v4 cache implementation in cache-v4.S sufficient for this

When the ixgbevf driver is opened the request to allocate MSIX irq
vectors may fail. In that case the driver will call ixgbevf_down()
which will call ixgbevf_irq_disable() to clear the HW interrupt
registers and calls synchronize_irq() using the msix_entries pointer in
the adapter structure. However, when the function to request the MSIX
irq vectors failed it had already freed the msix_entries which causes
an OOPs from using the NULL pointer in synchronize_irq().
The calls to pci_disable_msix() and to free the msix_entries memory
should not occur if device open fails. Instead they should be called
during device driver removal to balance with the call to
pci_enable_msix() and the call to allocate msix_entries memory
during the device probe and driver load.

Thanks to apple gpu mux fail we detect an eDP output, but can't read
anything over dp aux. In the resulting failure path we then hit a
paranoid WARN about potential locking.
Since the WARN is pretty useful for normal operation just paper over
it in the failure case by grabbing the demanded (but for init/teardown
not really required) lock.
I've checked our driver unload code and we already don't hold the kms
lock when calling drm_mode_config_cleanup. So this won't lead to a new
deadlock when reloading i915.ko.
v2: Make it compile.
