Configure the transmitter delay register at +0x1c to correctly handle
the CAN FD bitrate switch (BRS). This moves the SSP (secondary sample
point) to a proper offset, so that the TDC mechanism works and won't
generate error frames on the CAN link.

which lead to less number of queues getting allocated for 25G & 100G

E-switch mode changes involve creating HW tables, potentially allocating

The FW command output length should be only the length of struct

On a imx6ul-pico board the following error is seen during system suspend:
dpm_run_callback(): platform_pm_resume+0x0/0x54 returns -110
PM: Device 2090000.flexcan failed to resume: error -110
The reason for this suspend error is because when the CAN interface is not
active the clocks are disabled and then flexcan_chip_enable() will
always fail due to a timeout error.
In order to fix this issue, only call flexcan_chip_enable/disable()
when the CAN interface is active.

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64). Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.
Note that only the modifier will be packed differently between compat
and non-compat versions.

Commit 6e7333d "net: add rx_nohandler stat counter" added the new entry
rx_nohandler into struct rtnl_link_stats64. Unfortunately the bna
driver foolishly depends on the structure. It uses part of it for
ethtool statistics and it's not bad but the driver assumes its size
is constant as it defines string for each existing entry. The problem
occurs when the structure is extended because you need to modify bna
driver as well. If not any attempt to retrieve ethtool statistics results
in crash in bnad_get_strings().
The patch changes BNAD_ETHTOOL_STATS_NUM so it counts real number of
strings in the array and also removes rtnl_link_stats64 entries that
are not used in output and are always zero.

In case of error during netback_probe() (e.g. an entry missing on the
xenstore) netback_remove() is called on the new device, which will set
the device backend state to XenbusStateClosed by calling
set_backend_state(). However, the backend state wasn't initialized by
netback_probe() at this point, which will cause and invalid transaction
and set_backend_state() to BUG().
Initialize the backend state at the beginning of netback_probe() to
XenbusStateInitialising, and create two new valid state transitions on
set_backend_state(), from XenbusStateInitialising to XenbusStateClosed,
and from XenbusStateInitialising to XenbusStateInitWait.

Pull ARM fixes from Russell King:
"Most of this update are fixes primarily discovered from testing on the
older StrongARM 1110 and PXA systems, as a result of recent interest
from several people in these platforms:
- Locomo interrupt handling incorrectly stores the handler data in
the chip's private data slot: when Locomo is combined with an
interrupt controller who's chip uses the chip private data, this
leads to an oops.
- SA1111 was missing a call to clk_disable() to clean up after a
failed probe.
- SA1111 and PCMCIA suspend/resume was broken:
The PCMCIA "ds" layer was using the legacy bus suspend/resume
methods, which the core PM code is no longer calling as a result of
device_pm_check_callbacks() introduced in commit aa8e54b559479
("PM / sleep: Go direct_complete if driver has no callbacks").
SA1111 was broken due to changes to PCMCIA which makes PCMCIA
suspend itself later than the SA1111 code expects, and resume
before the SA1111 code has initialised access to the pcmcia
sub-device.
- the default SA1111 interrupt mask polarity got messed up when it
was converted to use a dynamic interrupt base number for its
interrupts.
- fix platform_get_irq() error code propagation, which was causing
problems on platforms where the interrupt may not be available at
probe time in DT setups.
- fix the lack of clock to PCMCIA code on PXA platforms, which was
omitted in conversions of PXA to CCF.
- fix an oops in the PXA PCMCIA code caused by a previous commit not
realising that Lubbock is different from the rest of the PXA PCMCIA
drivers.
- ensure that SA1111 low-level PCMCIA drivers propagate their error
codes to the main probe function, rather than the driver silently
accepting a failure.
- fix the sa11xx debugfs reporting of timing information, which
always indicated zero due to the clock being a factor of 1000 out.
- fix the polarity of the status change signal reported from the
sockets.
Lastly, one ARM specific commit from Stefan Agner fixing the LPAE
cache attributes"

The userspace memory region 'mr' is allocated with kzalloc in
__rvt_alloc_mr however it is incorrectly being freed with vfree in
__rvt_free_mr. Fix this by using kfree to free it.

rxe_requester() is sending a pkt with rxe_xmit_packet() and
then calls rxe_update() to update the wqe and qp's psn values.
But sometimes the response is received before the requester
had time to update the wqe in which case the completer
acts on errornous wqe values.
This fix updates the wqe and qp before actually sending
the request and rolls back when xmit fails.

When handling ack for atomic opcodes like "fetch&add"
or "cmp&swp", the method send_atomic_ack() saves the ack
before sending it, in case it gets lost and never reach the
requester. In which case the method duplicate_request()
will need to find it using the duplicated request.psn.
But send_atomic_ack() used a wrong psn value and thus
the above ack was never found.
This fix uses the ack.psn to locate the ack in case
its needed.
This fix also copies the ack packet to the skb's control buffer
since duplicate_request() will need it when calling rxe_xmit_packet()
