commit 2b85a34e911bf483c27cfdd124aeb1605145dc80
(net: No more expensive sock_hold()/sock_put() on each tx)
changed initial sk_wmem_alloc value.
We need to take into account this offset when reporting
sk_wmem_alloc to user, in PROC_FS files or various
ioctls (SIOCOUTQ/TIOCOUTQ)

If the adapter is not power-manageable using either ACPI, or the
native PCI PM interface, __e100_power_off() returns error code, which
causes every attempt to suspend to fail, although it should return 0
in such a case. Fix this problem by ignoring the return value of
pci_set_power_state() in __e100_power_off().

This patch is inspired by patch recently posted by Johannes Berg. Basically what
my patch does is to group list and a count of addresses into newly introduced
structure netdev_hw_addr_list. This brings us two benefits:
1) struct net_device becames a bit nicer.
2) in the future there will be a possibility to operate with lists independently
on netdevices (with exporting right functions).
I wanted to introduce this patch before I'll post a multicast lists conversion.

My previous patch, which explicitly delays freeing of tnodes by adding
them to the list to flush them after the update is finished, isn't
strict enough. It treats exceptionally tnodes without parent, assuming
they are newly created, so "invisible" for the read side yet.
But the top tnode doesn't have parent as well, so we have to exclude
all exceptions (at least until a better way is found). Additionally we
need to move rcu assignment of this node before flushing, so the
return type of the trie_rebalance() function is changed.

The logic in sky2_down was incorrect. Receiver could report status

Looking at the crash in log_martians(), one suspect is that the check for

0 on allocation, therefore skb_mac_header_was_set will always be true on

commit 2b85a34e911bf483c27cfdd124aeb1605145dc80
(net: No more expensive sock_hold()/sock_put() on each tx)
changed initial sk_wmem_alloc value.
Some protocols check sk_wmem_alloc value to determine if a timer
must delay socket deallocation. We must take care of the sk_wmem_alloc
value being one instead of zero when no write allocations are pending.
Reported by Ingo Molnar, and full diagnostic from David Miller.
This patch introduces three helpers to get read/write allocations
and a followup patch will use these helpers to report correct
write allocations to user.

The code to compute VPD size didn't handle some systems that use
chip without VPD. Also some of the newer chips use some additional
registers to store the actual size, and wasn't worth putting the
additional complexity in, so just remove the code.
No big loss since the code to set the VPD size was only a
convenience so that utilities would not read the extra space past
the end of the available VPD.
Move the first PCI config read earlier to detect bad hardware
where it returns all ones and refuse loading driver before furthur
damage.

When changing to a new BSSID or SSID, the code in
ieee80211_set_disassoc() needs to have the old data
still valid to be able to disconnect and clean up
properly. Currently, however, the old data is thrown
away before ieee80211_set_disassoc() is ever called,
so fix that by calling the function _before_ the old
data is overwritten.
This is (one of) the issue(s) causing mac80211 to hold
cfg80211's BSS structs forever, and them thus being
returned in scan results after they're long gone.

If we do not disconnect when a channel switch is requested,
we end up eventually detection beacon loss from the AP and
then disconnecting, without ever really telling the AP, so
we might just as well disconnect right away.
Additionally, this fixes a problem with iwlwifi where the
driver will clear some internal state on channel changes
like this and then get confused when we actually go clear
that state from mac80211.
It may look like this patch drops the no-IBSS check, but
that is already handled by cfg80211 in the wext handler it
provides for IBSS (cfg80211_ibss_wext_siwfreq).

Patch fixes the following bugs at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2005
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2007
If we suspend with an association and then resumed,
we need to synchronize the active rxon with staging rxon,
else we will get an error when iwl_alive_start try to commit
rxon and staging is set to channel 0. Before going to suspend
staging and active rxon are in sync. After resuming from the
suspend, iwl_mac_start is called and it clears the staging
rxon. Patch fixes the bug by not clearing the staging rxon
in iwl_mac_start.
Patch also adds similar fix to 3945.
