When queue_mode is NULL_Q_MQ and null_blk is being removed,
blk_cleanup_queue() isn't called to cleanup queue, so the queue
allocated won't be freed.
This patch calls blk_cleanup_queue() for MQ to drain all pending
requests first and release the reference counter of queue kobject, then
blk_mq_free_queue() will be called in queue kobject's release handler
when queue kobject's reference counter drops to zero.

crashes. From Erik Hugne
4) Fix access to uninitialized buffer in nf_nat netfilter code, from

they basically timeout immediately. From Hannes Frederic Sowa
6) Fix DMA unmapping of TSO packets in bnx2x driver, from Michal
Schmidt
7) Do not allow L2 forwarding offload via macvtap device, the way
things are now it will not end up being forwaded at all. From
Jason Wang
8) Fix transmit queue selection via ndo_dfwd_start_xmit(), fixing
things like applying NETIF_F_LLTX to the wrong device (!!) and
eliding the proper transmit watchdog handling

It can be a problem when a pattern is loaded via the firmware interface.
LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'.
So it should be deleted.
On the other hand, locks are required in store_engine_load()
on updating program memory.

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
will cause several issues:
- NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
instead of lower device which misses the necessary txq synchronization for
lower device such as txq stopping or frozen required by dev watchdog or
control path.
- dev_hard_start_xmit() was called with NULL txq which bypasses the net device
watchdog.
- dev_hard_start_xmit() does not check txq everywhere which will lead a crash
when tso is disabled for lower device.
Fix this by explicitly introducing a new param for .ndo_select_queue() for just
selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
forwarding transmission.
With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
dev_queue_xmit() to do the transmission.
In the future, it was also required for macvtap l2 forwarding support since it
provides a necessary synchronization method.

L2 fowarding offload will bypass the rx handler of real device. This will make
the packet could not be forwarded to macvtap device. Another problem is the
dev_hard_start_xmit() called for macvtap does not have any synchronization.
Fix this by forbidding L2 forwarding for macvtap.

bnx2x triggers warnings with CONFIG_DMA_API_DEBUG=y:
WARNING: CPU: 0 PID: 2253 at lib/dma-debug.c:887 check_unmap+0xf8/0x920()

different size [device address=0x00000000da2b389e] [map size=1490 bytes]
[unmap size=66 bytes]
The reason is that bnx2x splits a TSO BD into two BDs (headers + data)
using one DMA mapping for both, but it uses only the length of the first
BD when unmapping.
This patch fixes the bug by unmapping the whole length of the two BDs.

Starting with commit 80c33dd "net: add might_sleep() call to napi_disable"
bnx2x fails the might_sleep tests causing a stack trace to appear whenever
the driver is unloaded, as local_bh_disable() is being called before
napi_disable().
This changes the locking schematics related to CONFIG_NET_RX_BUSY_POLL,
preventing the need for calling local_bh_disable() and thus eliminating
the issue.

Commit 6d9252bd9a4bb (clk: Add support for power of two type dividers)
merged in v3.6 added the _get_val function to convert a divisor value to
a register field value depending on the flags. However it used the type
u8 for the div field, causing divisors larger than 255 to be masked
and the resultant clock rate to be too high.
E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down
to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This
was masked to 238 (0xee) resulting in a frequency of 103.26KHz.

The only BIOS on record that needs the 14 offset has a bios major
version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18
offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the
bios major version, look at the BMP version. BIOSes with BMP version 0
do not contain a detectable script, so always return 0 for them.

The existing serial state notification handling expected older Option
devices, having a hardcoded assumption that the Modem port was always
USB interface #2. That isn't true for devices from the past few years.
hso_serial_state_notification is a local cache of a USB Communications
Interface Class SERIAL_STATE notification from the device, and the
USB CDC specification (section 6.3, table 67 "Class-Specific Notifications")
defines wIndex as the USB interface the event applies to. For hso
devices this will always be the Modem port, as the Modem port is the
only port which is set up to receive them by the driver.
So instead of always expecting USB interface #2, instead validate the
notification with the actual USB interface number of the Modem port.

The AML method _BIX of NEC LZ750/LS returns a broken package which
skips the first member "Revision" (ACPI 5.0, Table 10-234).
Add a quirk for this machine to skip member "Revision" during parsing
the package returned by _BIX.

KVM environments do not support APERF/MPERF MSRs. intel_pstate cannot
operate without these registers.
The previous validity checks in intel_pstate_msrs_not_valid() are
insufficent in nested KVMs.

With arm:allmodconfig, building the Teles PCI driver fails with
telespci.c:294:2: error: #error "not running on big endian machines now"
Similar, building the driver for HFC PCI-Bus cards fails with
hfc_pci.c:1647:2: error: #error "not running on big endian machines now"
Remove the big endian cpp check from both drivers to fix the build errors.

When *only* the default RXQ is used, the RSS policy must be disabled so
that all IP and no-IP traffic is placed into the default RXQ. If not,
IP traffic is dropped.
Also, issue the RSS_CONFIG cmd only if FW advertises RSS capability for
the interface.

git://git.kernel.org/pub/scm/linux/kernel/git/tfiga/samsung-clk into clk-fixes
Samsung Clock fixes for 3.13-rc7
* Several patches fixing up incorrectly defined register addresses and
bitfield offsets that could lead to undefined operation when accessing
respective registers or bitfields.
1) clk: exynos5250: fix sysmmu_mfc{l,r} gate clocks
2a) clk: samsung: exynos5250: Fix ACP gate register offset
2b) clk: samsung: exynos5250: Add MDMA0 clocks
2c) ARM: dts: exynos5250: Fix MDMA0 clock number
3) clk: samsung: exynos4: Correct SRC_MFC register
All three issues have been present since Exynos5250 and Exynos4 clock
drivers were added by commits 6e3ad26816b72 ("clk: exynos5250:
register clocks using common clock framework") and e062b571777f5
("clk: exynos4: register clocks using common clock framework")
respectively.
* Patch to fix automatic disabling of Exynos5250 sysreg clock that could
cause undefined operation of several peripherals, such as USB, I2C,
MIPI or display block.
4) clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg
clock
Present since Exynos5250 clock drivers was added by commits
6e3ad26816b72 ("clk: exynos5250: register clocks using common clock
framework").
* Patch fixing compilation warning in clk-exynos-audss driver when
CONFIG_PM_SLEEP is disabled.
5) clk: exynos: File scope reg_save array should depend on PM_SLEEP
Present since the driver was added by commit 1241ef94ccc3 ("clk:
samsung: register audio subsystem clocks using common clock
framework").

If the hypervisor configures a vlan for the VF via the PF, the expected
result is that only packets tagged by said vlan will be received by the VF
(and that vlan will be silently removed).
Due to an incorrect manipulation of vlan filters in the driver, the
VF can receive untagged traffic even if the hypervisor configured
some vlan for it.
This patch corrects the behaviour.

There are 2 different (related) flows in the slowpath configuration
that utilize the same pointer and cast it to different structs;
This is obviously incorrect as the intended allocated memory is that
of the smaller struct, possibly causing the flow utilizing the larger
struct to corrupt other slowpath configuration.
Since both flows are exclusive, set the allocated memory to be a union
of both structs.
