The SET_LOOPBACK_MODE command is always issued from ethtool only in a
process context. So, while waiting for the cmd to complete, the driver
can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
only after the cmd completes while the MCCQ is locked).

This fix makes the RX_FILTER cmd asynchronous, i.e., the caller issues
this cmd and doesn't wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock
and keeping bottom halves disabled while the driver timesout waiting for
a response from the FW.

When packet encapsulation is in use, the MTU needs to be reduced for
headroom reservation.
The existing code takes the updated MTU value only from the host side.
But vSwitch extensions, such as Open vSwitch, require the flexibility
to change the MTU to different values from within a guest during the
lifecycle of a vNIC, when the encapsulation protocol is changed. The
patch supports this kind of MTU changes.

Part of commit 49aa284fe64c4c1 ("cxgb4: Add support for devlog")
change introduced a real bug where the Device Log Sequence Numbers are
no longer being converted from firmware Big-Endian to local CPU-Endian
format.
This patch moves all of the translation into the devlog_show() routine.
The only endianness code now in devlog_open() is the small loop to find the
earliest (lowest Sequence Number) Device Log entry in the circular buffer.

In enic_poll, we clean tx and rx queues, when low latency busy socket polling
is happening, enic_poll will only clean tx queue. After cleaning tx, it should
return total budget for re-poll.
There is a small window between vnic_intr_unmask() and enic_poll_unlock_napi().
In this window if an irq occurs and napi is scheduled on different cpu, it tries
to acquire enic_poll_lock_napi() and fails. Unlock napi_poll before unmasking
the interrupt.
v2:
Do not change tx wonk done behaviour. Consider only rx work done for completing
napi.

Pull module_platform_driver replacement from Paul Gortmaker:
"Replace module_platform_driver with builtin_platform driver in non
modules.
We see an increasing number of non-modular drivers using
modular_driver() type register functions. There are several downsides
to letting this continue unchecked:
- The code can appear modular to a reader of the code, and they won't
know if the code really is modular without checking the Makefile
and Kconfig to see if compilation is governed by a bool or
tristate.
- Coders of drivers may be tempted to code up an __exit function that
is never used, just in order to satisfy the required three args of
the modular registration function.
- Non-modular code ends up including the <module.h> which increases
CPP overhead that they don't need.
- It hinders us from performing better separation of the module init
code and the generic init code.
So here we introduce similar macros for builtin drivers. Then we
convert builtin drivers (controlled by a bool Kconfig) by making the
following type of mapping:
module_platform_driver() ---> builtin_platform_driver()
module_platform_driver_probe() ---> builtin_platform_driver_probe().
The set of drivers that are converted here are just the ones that
showed up as relying on an implicit include of <module.h> during a
pending header cleanup. So we convert them here vs adding an include
of <module.h> to non-modular code to avoid compile fails. Additonal
conversions can be done asynchronously at any time.
Once again, an unused module_exit function that is removed here
appears in the diffstat as an outlier wrt all the other changes"

Pull module_init replacement part two from Paul Gortmaker:
"Replace module_init with appropriate alternate initcall in non
modules.
This series converts non-modular code that is using the module_init()
call to hook itself into the system to instead use one of our
alternate priority initcalls.
Unlike the previous series that used device_initcall and hence was a
runtime no-op, these commits change to one of the alternate initcalls,
because (a) we have them and (b) it seems like the right thing to do.
For example, it would seem logical to use arch_initcall for arch
specific setup code and fs_initcall for filesystem setup code.
This does mean however, that changes in the init ordering will be
taking place, and so there is a small risk that some kind of implicit
init ordering issue may lie uncovered. But I think it is still better
to give these ones sensible priorities than to just assign them all to
device_initcall in order to exactly preserve the old ordering.
Thad said, we have already made similar changes in core kernel code in
commit c96d6660dc65 ("kernel: audit/fix non-modular users of
module_init in core code") without any regressions reported, so this
type of change isn't without precedent. It has also got the same
local testing and linux-next coverage as all the other pull requests
that I'm sending for this merge window have got.

up as an outlier upon casual inspection of the diffstat"

The conversion is a runtime no-op, since module_init actually becomes

"Four fixes have queued up to fix regressions introduced after v4.1:
- Don't fail IOMMU driver initialization when the add_device
call-back returns -ENODEV, as that just means that the device is
not translated by the IOMMU. This is pretty common on ARM.
- Two fixes for the ARM-SMMU driver for a wrong feature check and to
remove a redundant NULL check.
- A fix for the AMD IOMMU driver to fix a boot panic on systems where
the BIOS requests Unity Mappings in the IVRS table"

prevent it from triggering too early on some systems (Takashi Iwai)
- Prevent the cpuidle powernv driver from registering idle states

another module (yeah, really). Unfortunately that broke the usual

Add a early_enable module parameter to the omap_wdt that starts the
watchdog on module insertion. The default value is 0 which does not
start the watchdog - which also does not change the behavior if the
parameter is not given.
