All other code paths in sta_unblock synchronize with the network
softirq by using local_bh_disable/enable. Do the same around
ieee80211_sta_ps_deliver_wakeup.

mwl8k: fix condition in mwl8k_cmd_encryption_remove_key()
The intent here was to check whether key->cipher was WEP40 or WEP104.
We do a similar check correctly in several other places in this file.
The current condition is always true.

brcmfmac: work-around gcc 4.7 build issue
Alexandre Oliva <oliva@lsd.ic.unicamp.br> says:
"It's an issue brought about by GCC 4.7's partial-inlining, that ends up
splitting the udelay function just at the wrong spot, in such a way that
some sanity checks for constants fails, and we end up calling
bad_udelay.
This patch fixes the problem. Feel free to push it upstream if it makes
sense to you."

brcmsmac: remove PCI suspend/resume from bcma driver
The brcmsmac driver isn't a PCI driver any more, it's a bcma one. The
PCI device has been resumed by the PCI driver (the generic PCI layer,
really), we should be resuming just our own driver state.
Also add pr_debug() calls to show that we now actually get the
suspend/resume events.

If there was a dumping error in the middle, the set-specific variable was
not zeroed out and thus the 'done' function of the dumping wrongly tried
to release the already released reference of the set. The already released
reference was caught by __ip_set_put and triggered a kernel BUG message.

Net, mac80211: Fix resource leak in ieee80211_rx_h_mesh_fwding()
We may leak the 'fwd_skb' we skb_copy() in ieee80211_rx_h_mesh_fwding() if
we take the 'else' branch in the 'if' statement just below. If we take
that branch we'll end up returning from the function and since we've not
assigned 'fwd_skb' to anything at that point, we leak it when the variable
goes out of scope.
The simple fix seems to be to just kfree_skb(fwd_skb); just before we
return. That is what this patch does.

ath9k_hw: fix interpretation of the rx KeyMiss flag
Documentation states that the KeyMiss flag is only valid if RxFrameOK is
unset, however empirical evidence has shown that this is false.
When KeyMiss is set (and RxFrameOK is 1), the hardware passes a valid frame
which has not been decrypted. The driver then falsely marks the frame
as decrypted, and when using CCMP this corrupts the rx CCMP PN, leading
to connection hangs.
