Alexander Duyck 34a20e8973 igb: fix setting the number of tx queues
The real_num_tx_queues was not being set when in MSI-X only mode.  This patch
corrects that path so all interrupt types are correctly configured.

Alexander Duyck fe59de38c5 igb: ethtool -d reads EICR which is incorrect as it is read on clear
Ethtool -d is reading the EICR and ICR registers which is currently
clearing these registers and masking off interrupts.  To prevent this we
read the EICS and ICS equivilents as they can be read without clearing or
masking.

The commit c5dec1c303 introduced
__bio_copy_iov() to add bounce support to blk_rq_map_user_iov.

__bio_copy_iov() uses bio->bv_len to copy data for READ commands after
the completion but it doesn't work with a request that partially
completed. SCSI always completes a PC request as a whole but seems
some don't.

Adel Gadllah a4a778971b block: clean up cmdfilter sysfs interface
This patch changes the interface of the cmd filter to use a +/-
notation like:

echo -- +0x02 +0x03 -0x08

If neither + or - is given it defaults to + (allow command).

Note: The interface was added in 2.6.17-rc1 and is unused and
undocumented so far so it's safe to change it.

FUJITA Tomonori abf5439370 block: move cmdfilter from gendisk to request_queue
cmd_filter works only for the block layer SG_IO with SCSI block
devices. It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI
character devices (such as st). We hit a kernel crash with them.

The problem is that cmd_filter code accesses to gendisk (having struct
blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only
SCSI block device files. With character device files, inode->i_bdev
leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter
isn't safe.

SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be
independent on any protocols. We shouldn't change ULDs to expose their
gendisk.

This patch moves struct blk_scsi_cmd_filter from gendisk to
request_queue, a common object, which eveyone can access to.

The user interface doesn't change; users can change the filters via
/sys/block/. gendisk has a pointer to request_queue so the cmd_filter
code accesses to struct blk_scsi_cmd_filter.

The problem is found during iwlagn driver testing on
v2.6.27-rc4-176-gb8e6c91 kernel, but it turns out to be a lockdep bug.
In our testing, we frequently load and unload the iwlagn driver

behaviour?). The error message with the call trace is as below.

The root cause for this oops is in add_lock_to_list() when
save_trace() fails due to MAX_STACK_TRACE_ENTRIES is reached,
entry->class is assigned but entry is never added into any lock list.
This makes the list_del_rcu() in zap_class() oops later when the
module is unloaded. This patch fixes the problem by assigning
entry->class after save_trace() returns success.

Jan-Espen Pettersen 8ab65b03b7 mac80211: don't send empty extended rates IE
The association request includes a list of supported data rates.

802.11b: 4 supported rates.
802.11g: 12 (8 + 4) supported rates.
802.11a: 8 supported rates.

The rates tag of the assoc request has room for only 8 rates. In case of
802.11g an extended rate tag is appended. However in net/wireless/mlme.c
an extended (empty) rate tag is also appended if the number of rates is
exact 8. This empty (length=0) extended rates tag causes some APs to
deny association with code 18 (unsupported rates). These APs include my
ZyXEL G-570U, and according to Tomas Winkler som Cisco APs.

'If count == 8' has been used to check for the need for an extended rates
tag. But count would also be equal to 8 if the for loop exited because of
no more supported rates. Therefore a check for count being less than
rates_len would seem more correct.

Thanks to:
 * Dan Williams for newbie guidance
 * Tomas Winkler for confirming the problem

Jouni Malinen 93015f0f34 mac80211: Fix debugfs file add/del for netdev
Previous version was using incorrect union structures for non-AP
interfaces when adding and removing max_ratectrl_rateidx and
force_unicast_rateidx entries. Depending on the vif type, this ended
up in corrupting debugfs entries since the dentries inside different
union structures ended up going being on top of eachother.. As the
end result, debugfs files were being left behind with references to
freed data (instant kernel oops on access) and directories were not
removed properly when unloading mac80211 drivers. This patch fixes
those issues by using only a single union structure based on the vif
type.

Jouni Malinen 087d833e5a mac80211: Use IWEVASSOCREQIE instead of IWEVCUSTOM
The previous code was using IWEVCUSTOM to report IEs from AssocReq and
AssocResp frames into user space. This can easily hit the 256 byte
limit (IW_CUSTOM_MAX) with APs that include number of vendor IEs in
AssocResp. This results in the event message not being sent and dmesg
showing "wlan0 (WE) : Wireless Event too big (366)" type of errors.

Convert mac80211 to use IWEVASSOCREQIE/IWEVASSOCRESPIE to avoid the
issue of being unable to send association IEs as wireless events. These
newer event types use binary encoding and larger maximum size
(IW_GENERIC_IE_MAX = 1024), so the likelyhood of not being able to send
the IEs is much smaller than with IWEVCUSTOM. As an extra benefit, the
code is also quite a bit simpler since there is no need to allocate an
extra buffer for hex encoding.

Jiri Slaby 67d2e2dfab Ath5k: fix bintval setup
bintval is set to the initial value at .config_interface which is too
late, since it overwrites previously set value from .config. Move the
initialization to the .add_interface.

Jiri Slaby 004829730c Ath5k: lock beacons
Beacons setup and config was racy with beacon send. Ensure that
ISR and reset functions see consistent state of bbuf.

Use also dev_kfree_skb_any in ath5k_txbuf_free since we call it
from atomic now.

Dan Williams 3c34a5d821 atmel: return ENOENT on request_firmware failure
Return errors from request_firmware() (like other drivers that do
firmware load on device open) and make up plausible codes for other
error conditions. Gives userspace tools like NetworkManager a clue that
firmware may be missing when the result of setting IFF_UP is ENOENT.
