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.

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.

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.

Commit 6d9252bd9a (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.

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.

and a maximum of 1.5V. This is indicated by bit 4 of FUSE7.

The driver wrongly assumes 16 EQs/vectors are available for each BE3 PF.
When SR-IOV is enabled, a BE3 PF can support only a max of 8 EQs.
