e374055afb mac80211: Reset assoc_scan_tries after an unsuccessful scan run
Trying to associate with a non-existent SSID stops the
state machine after the first run. Subsequent association
requests fail to start the scan engine. Fix this by resetting
assoc_scan_tries to zero after completing a scan run.

7519a8f077 ath9k: remove passive scan on 5 GHz if country IE knows better
If we have new found information about our location and the
current country regulatory domain does not have passive scan
flag requirements we should be able to actively scan now on those
channels.

Since AP functionality is not allowed where passive scan flags are
set this means if you have a world regulatory domain and you get a
country IE that allows that channel (with active scan) then we lift
the passive-scan requirement so you can then use AP mode.

0cbe006461 rt2x00: Validate firmware in driver
The get_firmware_crc() callback function isn't flexible
enough when dealing with multiple firmware versions.
It might in some cases be possible that the firmware
file contains multiple CRC checksums.

Create the check_firmware() callback function where the driver
has complete freedom in how to validate the firmware.

8ccde88a87 iwl3945: Getting rid of the *39_rxon iwl_priv fields
The iwl_rxon_cmd is really just a iwl3945_rxon_cmd structure extension.
So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific
ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host
commands, since the command length as to be set according to the HW. As
another precaution the reserved4 and reserved5 fields are cleared before being
sent to the 3945.

With the *39_rxon removal, a lot of duplicated code can be removed from the
3945 code base.

The "no DMA on stack" conversion was incomplete with respect to
updating the arguments passed to usb_control_msg.  The value 40 is
hardcoded as it was prior to conversion.

The driver can now load firmware, but is not fully functional.

Turns out that we don't want the mac80211 port of this driver just yet, as
there is a different driver working on adding this support.

So keep things old and different for now.

This is being reverted at the request of the linux-wireless developers.

af3ddbd763 USB: fsl_qe_udc: Fix stalled TX requests bug
While disabling an endpoint the driver nuking any pending requests,
thus completing them with -ESHUTDOWN status. But the driver doesn't
clear the tx_req, which means that a next TX request (after
ep_enable), might get stalled, since the driver won't queue the new
reqests.

This patch fixes a bug I'm observing with ethernet gadget while
playing with ifconfig usb0 up/down (the up/down sequence disables
and enables `in' and `out' endpoints).

82341b3690 USB: fsl_qe_udc: Fix muram corruption by disabled endpoints
Before freeing an endpoint's muram memory, we should stop all activity
of the endpoint, otherwise the QE UDC controller might do nasty things
with the muram memory that isn't belong to that endpoint anymore.

The qe_ep_reset() effectively flushes the hardware fifos, finishes all
late transaction and thus prevents the corruption.

ef84e4055f USB: fsl_qe_udc: Fix disconnects reporting during bus reset
Freescale QE UDC controllers can't report the "port change" states,
so the only way to handle disconnects is to process bus reset
interrupts. The bus reset can take some time, that is, few irqs.
Gadgets may print the disconnection events, and this causes few
repetitive messages in the kernel log.

This patch fixes the issue by using the usb_state machine, if the
usb controller has been already reset, just quit the reset irq
early.

2247818a32 USB: fsl_qe_udc: Fix QE USB controller initialization
qe_udc_reg_init() leaves the USB controller enabled before muram memory
initialized. Sometimes the uninitialized muram memory confuses the
controller, and it start sending the busy interrupts.

Fix this by disabling the controller, it will be enabled later by
the gadget driver, at bind time.

a30551db66 USB: fsl_qe_udc: Fix recursive locking bug in ch9getstatus()
The call chain is this:

qe_udc_irq() <- grabs the udc->lock spinlock
rx_irq()
qe_ep0_rx()
ep0_setup_handle()
setup_received_handle()
ch9getstatus()
qe_ep_queue() <- tries to grab the udc->lock again

It seems unsafe to temporarily drop the lock in the ch9getstatus(),
so to fix that bug the lock-less __qe_ep_queue() function
implemented and used by the ch9getstatus().

94f341db3d USB: fsl_qe_udc: Fix oops on QE UDC probe failure
In case of probing errors the driver kfrees the udc_controller, but it
doesn't set the pointer to NULL.

When usb_gadget_register_driver is called, it checks for udc_controller
!= NULL, the check passes and the driver accesses nonexistent memory.
Fix this by setting udc_controller to NULL in case of errors.

While at it, also implement irq_of_parse_and_map()'s failure and cleanup
cases.

9d9b87c121 lockd: fix regression in lockd's handling of blocked locks
If a client requests a blocking lock, is denied, then requests it again,
then here in nlmsvc_lock() we will call vfs_lock_file() without FL_SLEEP
set, because we've already queued a block and don't need the locks code
to do it again.

But that means vfs_lock_file() will return -EAGAIN instead of
FILE_LOCK_DENIED.  So we still need to translate that -EAGAIN return
into a nlm_lck_blocked error in this case, and put ourselves back on
lockd's block list.

The bug was introduced by bde74e4bc6 "locks: add special return
value for asynchronous locks".

Thanks to Frank van Maarseveen for the report; his original test
case was essentially

	for i in `seq 30`; do flock /nfsmount/foo sleep 10 & done

Architectures other than mips and x86 are not using ticket spinlocks.
Therefore, the contention on the lock is meaningless, since there is
nobody known to be waiting on it (arguably /fairly/ unfair locks).

Dummy it out to return 0 on other architectures.
