The module parameter ieee80211_disable_40mhz_24ghz
was meant to allow disabling 40 MHz operation in
the 2.4 GHz band by default. However, it is buggy
as implemented because while it advertises to the
AP that the device doesn't support 40 MHz, it will
itself still use 40 MHz configurations.
To fix this, clear the 40 MHz bits from the sband
completely instead of overriding where used.

Correct channel setting function must be used for AR2317.
When I tested ahb patch on bullet2 all seemed to work fine,
but it couldn't connect another host (using ibss for example).
During an analysis I observed that it's transmitting on another
channel. I looked into madwifi code and understood that
the problem is in channel setting function. So atheros RF2317 not
fully handled in the current ath5k version and must be patched.

Eric W. Biderman and Michal Hocko reported various memory corruptions
that we suspected to be related to a LIST head located on stack, that
was manipulated after thread left function frame (and eventually exited,
so its stack was freed and reused).
Eric Dumazet suggested the problem was probably coming from commit
443457242b (net: factorize
sync-rcu call in unregister_netdevice_many)
This patch fixes __dev_close() and dev_close() to properly deinit their
respective LIST_HEAD(single) before exiting.

When list debugging is enabled, we aim to readably show list corruption
errors, and the basic list_add/list_del operations end up having extra
debugging code in them to do some basic validation of the list entries.
However, "list_del_init()" and "list_move[_tail]()" ended up avoiding
the debug code due to how they were written. This fixes that.
So the _next_ time we have list_move() problems with stale list entries,
we'll hopefully have an easier time finding them..

We believe that our earlier patch for supporting multiple hardware
receive queues per enic device requires more internal testing. At this
point, we think that it's best to disable the use of multiple receive
queues. The current patch provides an effective means for the same.
Also, we continue to disallow multiple hardware transmit queues per
device. But change the way we enforce this in order to maintain
consistency with the way receive queues are handled.

GCC emits all kinds of crazy zero extensions when we go from signed
int, to unsigned short, etc. etc.
This transformation has to be legal because:
1) In tkey_extract_bits() in mask_pfx(), the values are used to
perform shifts, on which negative values are undefined by C.
2) In fib_table_lookup() we perform comparisons with unsigned
values, constants, and additions. None of which should
encounter negative values.

1) Make __mkroute_output() return error pointers.

Uwe pointed out that my alarm based UIE emulation is not sufficient
to replace the older timer/polling based UIE emulation on devices
where there is no alarm irq. This causes rtc devices without alarms
to return -EINVAL to UIE ioctls. The fix is to re-instate the old
timer/polling method for devices without alarm irqs.
This patch reverts the following commits:
042620a018 - Remove UIE emulation
1daeddd596 - Cleanup removed UIE emulation declaration
b5cc8ca1c9 - Remove Kconfig symbol for UIE emulation
The emulation mode will still need to be wired-in with a following
patch before it will work.
