Commit 1f0f467b "qlcnic: Add hwmon interface to export board
temperature" introduced a randconfig build error in the case
when the hwmon framework is built as a module and the qlcnic
driver itself is built-in:

drivers/built-in.o: In function `qlcnic_register_hwmon_dev':
drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1301:

drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1309:
undefined reference to `hwmon_device_unregister'.

This changes the Kconfig logic to enforce that the qlcnic hwmon
support can only be enabled if it is possible to successfully
build it.

commit 8f0ea0fe (snmp: reduce percpu needs by 50%)
reduced snmp array size to 1, so technically it doesn't have to be
an array any more. What's more, after the following commit:

	commit 933393f5
	Date:   Thu Dec 22 11:58:51 2011 -0600

	    percpu: Remove irqsafe_cpu_xxx variants

	    We simply say that regular this_cpu use must be safe regardless of
	    preemption and interrupt state.  That has no material change for x86
	    and s390 implementations of this_cpu operations.  However, arches that
	    do not provide their own implementation for this_cpu operations will
	    now get code generated that disables interrupts instead of preemption.

probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after
almost 3 years, no one complains.

So, just convert the array to a single pointer and remove snmp_mib_init()
and snmp_mib_free() as well.

tipc: purge signal handler infrastructure

When we delay some actions to be executed in asynchronous contexts,
these usually add unnecessary code complexities, and make their
behaviours unpredictable and indeterministic. Moreover, as the signal
handler infrastructure is first stopped when tipc module is removed,
this may cause some potential risks for us. For instance, although
signal handler is already stopped, some tipc components still submit
signal requests to signal handler infrastructure, which may lead to
some resources not to be released or freed correctly.

So the series aims to convert all actions being performed in tasklet
context asynchronously with interface provided by signal handler
infrastructure to be executed synchronously, thereby deleting the
whole infrastructure of signal handler.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In the previous commits of this series, we removed all asynchronous
actions which were based on the tasklet handler - "tipc_k_signal()".

So the moment has now come when we can completely remove the tasklet
handler infrastructure. That is done with this commit.

This introduces another flag in 'quirks' to replace the preprocessor
define (USE_MMIO) used to indicate whether the device needs a
separate enable routine to operate in MMIO mode.

All of the currently known platform Rhine cores operate in MMIO
mode by default, and on PCI it is preferred over PIO for performance
reasons. However, a comment in code suggests that some (?) early
Rhine cores only work in PIO mode, so they should not be switched
to MMIO.

Enabling MMIO on PCI is still triggered by the same Kconfig option
to avoid breaking user configs needlessly, but this can be changed
going forward towards automatic runtime detection in case a list of
PIO-only Rhine revisions can be compiled.

This also fixes a couple of compiler warnings detected by Fengguang
Wu's test bot (!USE_MMIO case):

net: Checksum offload changes

I am working on overhauling RX checksum offload. Goals of this effort
are:

- Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY
- Preserve CHECKSUM_COMPLETE through encapsulation layers
- Don't do skb_checksum more than once per packet
- Unify GRO and non-GRO csum verification as much as possible
- Unify the checksum functions (checksum_init)
- Simply code

What is in this first patch set:

- Create a common "checksum_init" function which is called from
  TCPv{4,6} and UDPv{4,6}
- Add some for RFC6936, UDP/IPv6 zero checksums
- Add architecture support for csum_add and provide implementations
  for x86_64 and Sparc 32 and 64 bit (please test the latter)

Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)

RFC 6936 relaxes the requirement of RFC 2460 that UDP/IPv6 packets which
are received with a zero UDP checksum value must be dropped. RFC 6936
allows zero checksums to support tunnels over UDP.

When sk_no_check is set we allow on a socket we allow a zero IPv6
UDP checksum. This is for both sending zero checksum and accepting
a zero checksum on receive.

* fix memory allocation failures after a firmware crash (Michal)

* some rework of DFS configuration to enable it correctly in all cases
  (Michal)

* add a new firmware crash option to make it possible to crash 10.1
  firmware for testing purposes (Marek P)

* fix RTS/CTS protection in certain cases (Marek K)

* fix wrong RSSI and rate reporting in some cases (Janusz)

* fix firmware stats reporting (Chun, Ben & Bartosz)"

For the iwlwifi bits, Emmanuel says:

"I have here a bunch of unrelated things. I disabled support for
-7.ucode which means that I can removed a lot of code. Eliad has
a brand new feature: we reduce the Tx power when the link allows -
this reduces our power consumption. The regular changes in power and
scan area. One interesting thing though is the patches from Johannes,
we have now GRO which allows to increase our throughput in TCP Rx. The
main advantage is that it reduces the number of TCP Acks - these TCP
Acks are completely useless when we are using A-MPDU since the first
packet of the A-MPDU generates a TCP Ack which is made obsolete by
the next packets."

Along with that, there are a variety of updates to b43, mwifiex,
rtl8180 and wil6210 drivers and a handful of other updates here
and there.
