commit a9b3cd7f (rcu: convert uses of rcu_assign_pointer(x, NULL) to
RCU_INIT_POINTER) did a lot of incorrect changes, since it did a
complete conversion of rcu_assign_pointer(x, y) to RCU_INIT_POINTER(x,
y).

We miss needed barriers, even on x86, when y is not NULL.

No need to lock soft irqs under bond_alb_xmit()
which already has softirq disabled.

Changes:
1. add non-bh/bh version to tlb_clear_slave()

2. represent BH and non BH hash table locks

    mac80211: consolidate MIC failure report handling

is possible to that we dereference rx->key == NULL when driver set
RX_FLAG_MMIC_STRIPPED and not RX_FLAG_IV_STRIPPED and we are in
promiscuous mode. This happen with rt73usb and rt61pci at least.

Before the commit we always check rx->key against NULL, so I assume
fix should be done in mac80211 (also mic_fail path has similar check).

My patch to validate station flags broke compatibility
with the old station flags setting where all flags are
always set at once since it always set the mask as all
possible flags which ended up being rejected later in
the station add/modify code.

Fix by parsing only the current flags in the old flags
attribute -- new applications and new flags should use
(and will now require) the new flags attribute where
the mask is given by the application.

In kernel v3.2 initialization sequence for Asix 88178 devices was changed so
that hardware is reseted on every time interface is brought up (ifconfig up),
instead just at USB probe time. This causes problem with setting custom MAC
address to device as ax88178_reset causes reload of MAC address from EEPROM.

This patch fixes the issue by rewriting MAC address at end of ax88178_reset.

The commit "ath9k: Fix invalid noisefloor reading due to channel update"
preserves the current channel noisefloor readings before updating
channel type at the same channel index. It is also updating the curchan
pointer. As survey updation is also referring curchan pointer to fetch
the appropriate index, which might leads to invalid memory access. This
patch partially reverts the change and stores the noise floor history
buffer before updating channel type w/o updating curchan.

If the memory allocation 'nvram_ularray = kmalloc(varsize,
GFP_ATOMIC);' fails we'll leak the memory allocated to 'vbuffer' when
we return -ENOMEM from the function.

This patch resolves the leak by kfree()'ing the allocated memory
before the return.
