73a3707953 forcedeth: fix dma api mismatches
forcedeth doesnt use properly dma api in its tx completion path
and in nv_loopback_test()

pci_map_single() should be paired with pci_unmap_single()
pci_map_page() should be paired with pci_unmap_page()

forcedeth xmit path uses pci_map_single() & pci_map_page(),
but tx completion path only uses pci_unmap_single()

nv_loopback_test() uses pci_map_single() & pci_unmap_page()

Add a dma_single field in struct nv_skb_map, and
define a helper function nv_unmap_txskb

81e2a3d5b7 atm: sk_wmem_alloc initial value is one
commit 2b85a34e91
(net: No more expensive sock_hold()/sock_put() on each tx)
changed initial sk_wmem_alloc value.

This broke net/atm since this protocol assumed a null
initial value. This patch makes necessary changes.

6905b1f1a0 Net / e100: Fix suspend of devices that cannot be power managed
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().

31278e7147 net: group address list and its count
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.

7b85576d15 ipv4: Fix fib_trie rebalancing, part 2
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.

c564039fd8 net: sk_wmem_alloc has initial value of one, not zero
commit 2b85a34e91
(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.

6cc90a5a60 sky2: don't look for VPD size
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.

1fa6f4af9f mac80211: fix wext bssid/ssid setting
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.

7e9debe978 mac80211: disconnect when user changes channel
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).

8a9b99267c iwlwifi/iwl3945: fix suspend resume association bug
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.

d7129e190c iwlwifi: revamp bss_info_changed
My earlier patch,
	"mac80211: unify config_interface and bss_info_changed"
introduced a bug in iwlwifi where it will do some things
incorrectly now when reassociating.

Revamp iwl_bss_info_changed to fix that issue and make it
easier to read. Also, while at it, add comments about things
that it should do but currently doesn't.

Finally, also improve the locking in the function.
