Starting with commit 2dc33bbc "bnx2x: Remove the sriov VFOP mechanism",
the bnx2x started enforcing vlan credits for all vlan configurations.
This exposed 2 issues:
- Vlan credits are not returned once a VF is removed; this causes a leak
of credits, and eventually will lead to VFs with no vlan credits.
- A vlan credit must be set aside for the Hypervisor to use, and should
not be visible to the VF.
Although linux VFs at the moment do not support vlan configuration [from the
VF side] which causes them to be resilient to this sort of issue, Windows VF
over linux hypervisors might fail to load as the vlan credits become depleted.

fs_path_ensure_buf is used to make sure our path buffers for
send are big enough for the path names as we construct them.
The buffer size is limited to 32K by the length field in
the struct.
But bugs in the path construction can end up trying to build
a huge buffer, and we'll do invalid memmmoves when the
buffer length field wraps.
This patch is step one, preventing the overflows.

The whole IIO subsystem can be built as modules. If you make it a
module then stuff marked as "Y" in the adc directory simply won't be
linked in properly.
The two configs that were wrong were EXYNOS_ADC and LP8788_ADC. I
know for a fact that EXYNOS_ADC will work as a module. I assume
LP8788_ADC will also be fine.

Using pdev->dev with device_for_each_child() would iterate over all
of the children of the platform device and delete them.
Thus, causing crashes during module unload.
We should be using the indio_dev->dev structure for
registering/unregistering child nodes.

The mmu-gather operation 'tlb_flush_mmu()' has done two things: the
actual tlb flush operation, and the batched freeing of the pages that
the TLB entries pointed at.
This splits the operation into separate phases, so that the forced
batched flushing done by zap_pte_range() can now do the actual TLB flush
while still holding the page table lock, but delay the batched freeing
of all the pages to after the lock has been dropped.
This in turn allows us to avoid a race condition between
set_page_dirty() (as called by zap_pte_range() when it finds a dirty
shared memory pte) and page_mkclean(): because we now flush all the
dirty page data from the TLB's while holding the pte lock,
page_mkclean() will be held up walking the (recently cleaned) page
tables until after the TLB entries have been flushed from all CPU's.

The codec is defined both in DT and the board file. The board file
however contains platform data which is required in order that the
codec works. When the DT instantiates the codec before the board files
does, it is missing the platform data and so fails. Remove the DT node
until we have a binding which can pass the additional data.

In commit 249f382250 ('ARM: mvebu: add
audio support to Armada 370 DB'), the I2C bus 0 was enabled on the
Armada 370 DB board, and an I2C codec was described as being connected
on this bus.
However, this commit forgot to define the I2C bus frequency, which
leads the i2c-mv64xxx to fail probing, as it cannot calculate the baud
rate multiplier/divisor to derive the I2C bus frequency from the core
SoC frequency. It makes audio completely unusable, as the I2C bus is
not probed, and therefore the audio codec is not probed either.

The Armada XP GP isn't using rgmii-id connections between the MAC and
PHY, but instead a single QSGMII connection, which is a quad-SGMII
connection: a double pair of differential lines that are multiplexed
to convey the traffic of four network interfaces between a MAC and a
PHY.
Until now, the Armada XP GP was relying on the bootloader setting the
correct values in various configuration registers. With this change,
the mvneta driver can be used as a module on this platform.

The mvebu-devbus driver had a serious bug, which lead to a 8 bits bus
width declared in the Device Tree being considered as a 16 bits bus
width when configuring the hardware.
This bug in mvebu-devbus driver was compensated by a symetric mistake
in the Armada XP OpenBlocks AX3 Device Tree: a 8 bits bus width was
declared, even though the hardware actually has a 16 bits bus width
connection with the NOR flash.

While updating how mmap enabled kernfs files are handled by lockdep,
9b2db6e189 ("sysfs: bail early from kernfs_file_mmap() to avoid
spurious lockdep warning") inadvertently dropped error return check
from kernfs_file_mmap(). The intention was just dropping "if
(ops->mmap)" check as the control won't reach the point if the mmap
callback isn't implemented, but I mistakenly removed the error return
check together with it.
This led to Xorg crash on i810 which was reported and bisected to the
commit and then to the specific change by Tobias.

Currently kernfs_link_sibling() increates parent->dir.subdirs before
adding the node into parent's chidren rb tree.
Because it is possible that kernfs_link_sibling() couldn't find
a suitable slot and bail out, this leads to a mismatch between
elevated subdir count with actual children node numbers.
This patches fix this problem, by moving the subdir accouting
after the actual addtion happening.

The mailbox module is capable of generating two interrupts
to MPU in OMAP2420, compared to one in OMAP2430. The second
interrupt is to handle interrupts from the additional IVA
processor present only on OMAP2420.
Move the current common mailbox DT node into the SoC
specific files to allow the above differentiation. Also,
added back the interrupt-names on OMAP2420, that were
previously defined in hwmod data.
This fixes regression caused by the recent dropping of
hwmod data in favor for defining it in the .dts files.

On my DRA7 system, when the kernel is built in Thumb-2 mode, the secondary CPU
(Cortex A15) fails to come up causing SMP boot on second CPU to timeout. This
seems to be because the CPU is in ARM mode once the ROM hands over control to
the kernel. Switch to Thumb-2 mode if required once the kernel is control of
secondary CPU. On OMAP4 on the other hand, it appears to be in Thumb-2 mode on
entry so this is not required and SMP boot works as is.
Also corrected a spurious '+' and updated copyright information.

The same issue like with Panther Point chipsets. If the USB ports are
switched to xHCI on shutdown, the xHCI host will send a spurious interrupt,
which will wake the system. Some BIOS have work around for this, but not all.
One example is Compulab's mini-desktop, the Intense-PC2.
The bug can be avoided if the USB ports are switched back to EHCI on
shutdown.
This patch should be backported to stable kernels as old as 3.12,
that contain the commit 638298dc66

We have observed a rare cycle state desync bug after Set TR Dequeue
Pointer commands on Intel LynxPoint xHCs (resulting in an endpoint that
doesn't fetch new TRBs and thus an unresponsive USB device). It always
triggers when a previous Set TR Dequeue Pointer command has set the
pointer to the final Link TRB of a segment, and then another URB gets
enqueued and cancelled again before it can be completed. Further
investigation showed that the xHC had returned the Link TRB in the TRB
Pointer field of the Transfer Event (CC == Stopped -- Length Invalid),
but when xhci_find_new_dequeue_state() later accesses the Endpoint
Context's TR Dequeue Pointer field it is set to the first TRB of the
next segment.
The driver expects those two values to be the same in this situation,
and uses the cycle state of the latter together with the address of the
former. This should be fine according to the XHCI specification, since
the endpoint ring should be stopped when returning the Transfer Event
and thus should not advance over the Link TRB before it gets restarted.
However, real-world XHCI implementations apparently don't really care
that much about these details, so the driver should follow a more
defensive approach to try to work around HC spec violations.
This patch removes the stopped_trb variable that had been used to store
the TRB Pointer from the last Transfer Event of a stopped TRB. Instead,
xhci_find_new_dequeue_state() now relies only on the Endpoint Context,
requiring a small amount of additional processing to find the virtual
address corresponding to the TR Dequeue Pointer. Some other parts of the
function were slightly rearranged to better fit into this model.
This patch should be backported to kernels as old as 2.6.31 that contain
the commit ae63674714 "USB: xhci: URB
cancellation support."

be justified from EL1, do_debug_exception will already do the right thing,

Depending on the SDVO output_flags SDVO may have multiple connectors
linking to the same encoder (in intel_connector->encoder->base).
Only one of those connectors should be active (ie link to the encoder
thru drm_connector->encoder).
If intel_connector_break_all_links() is called from intel_sanitize_crtc()
we may break the crtc connection of an encoder thru an inactive connector
in which case intel_connector_break_all_links() will not be called again
for the active connector if this happens to come later in the list due to:
if (connector->encoder->base.crtc != &crtc->base)
continue;
in intel_sanitize_crtc().
This will however leave the drm_connector->encoder linkage for this
active connector in place. Subsequently this will cause multiple
warnings in intel_connector_check_state() to trigger and the driver
will eventually die in drm_encoder_crtc_ok() (because of crtc == NULL).
To avoid this remove intel_connector_break_all_links() and move its
code to its two calling functions: intel_sanitize_crtc() and
intel_sanitize_encoder().
This allows to implement the link breaking more flexibly matching
the surrounding code: ie. in intel_sanitize_crtc() we can break the
crtc link separatly after the links to the encoders have been
broken which avoids above problem.
This regression has been introduced in:
