This patch fixes the issue specific to AP. AP is started with WEP
security and external station is connected to it. Data path works
in this case. Now if AP is restarted with WPA/WPA2 security,
station is able to connect but ping fails.
Driver skips the deletion of WEP keys if interface type is AP.
Removing that redundant check resolves the issue.

As reported by Felix:
Though protected by an ifdef, introducing an usb symbol dependency in
the rt2x00lib module is a major inconvenience for distributions that
package kernel modules split into individual packages.
Get rid of this unnecessary dependency by calling the usb related
function from a more suitable place.

This new helper reads extra frequency limits specified in DT and
disables unavailable chanels. This is useful for devices (like home
routers) with chipsets limited e.g. by board design.
In order to respect info read from DT we simply need to check for
IEEE80211_CHAN_DISABLED bit when constructing channel info.

The Egret system controller was the predecessor to the Cuda and the
differences are minor.
On Cuda, byte acknowledgement requires one transition of the TACK
signal; on Egret two are needed. On Cuda, TIP is active low; on Egret
it is active high. And Cuda raises certain interrupts that Egret omits.
Accomodating these differences complicates the Cuda driver slightly
but avoids a lot of duplication (see next patch).

Initialize data_index where appropriate to improve readability and
assist debugging. This change doesn't affect driver behaviour.
I prefer to see
current_req->data[data_index++]
in place of
current_req->data[0]
or
current_req->data[1]
inasmuchas it becomes obvious what the data_index variable does.
Moreover, the actual value of data_index when examined at any given moment
tells me something about prior events, which did prove helpful.

The cuda_start() function uses spinlock_irq_save/restore for mutual
exclusion. Let's have cuda_poll() do the same when polling the VIA
interrupt.
The benefit to disabling local irqs when the interrupt is being polled
is that the interrupt handler now has the same timing properties
regardless of whether it is invoked normally or from cuda_poll().
This driver was written back when local irqs remained enabled during
execution of interrupt handlers and cuda_poll() was probably trying
to achieve the same effect by use of enable/disable_irq.

When a read transaction completes, one of several things will happen:
a new transfer is started by the driver, a new transfer request
is raised by the Cuda (i.e. TREQ asserted), or both happen at once.
When both happen at once, there is a race condition between the TREQ test
in the read_done state and the same test in cuda_start(). Moreover, the
former test uses a stale TREQ value.
Theoretically, this can result in the undesirable outcome that the
interrupt handler completes with the state machine 'idle' when it should
instead start the next transaction.
Avoid this race by calling cuda_start() first and then confirming that it
succeeded. If not, test the current TREQ value before entering the
'reading' state.

When reading_reply is set, reply_ptr points into an adb_request struct.
Conversely, when reply_ptr instead points into the global cuda_rbuf,
reading_reply must be false.
Unfortunately, this rule can be violated because re-initialization
of reply_ptr and reading_reply presently depends on the TREQ input.
Fix this by re-initializing reply_ptr and reading_reply as soon as they
are known to be invalid.

Introduce some helpers for handling the signalling between VIA and
Cuda. This abstraction will be used to add support for Egret devices,
which utilize slightly different signalling.
Don't invert the sense of the Cuda's active-low signals when storing
them in the 'status' variable. Just assert, negate and test those
signals using the helpers.
The state machine does not need to test its own output signals to
figure out what to do next: the next state depends on the Cuda's TREQ
output. Just call the TREQ_asserted() helper function to test for that.
Similarly, there is no need to store pin directions in the 'status'
variable. That was only useful for debugging messages.

assumes, but if the administrator specifies a non-default
4K-alignment then we can fail to correctly size the reservation.
- A one line fix to improve the predictability of libnvdimm block
device names. A common operation is to reconfigure /dev/pmem0 into
a different mode. For example, a reconfiguration might set a new
mode that reserves some of the capacity for a struct page memmap
array. It surprises users if the device name changes to
"/dev/pmem0.1" after the mode change and then back to /dev/pmem0
after a reboot.

Commit 618f535a6062 ("ACPI/IORT: Add single mapping function")
introduced a function (iort_node_get_id()) to retrieve ids for IORT
named components.
The iort_node_get_id() takes an index as input to refer to a specific
mapping entry in the named component IORT node mapping array.
For a mapping entry at a given index, iort_node_get_id() should return
the id value (through the id_out function parameter) and the IORT node
output_reference (through function return value) the given mapping entry
refers to.
Technically output_reference values may differ for different map
entries, (see diagram below - mapped id values may refer to different eg
IORT SMMU nodes; the kernel may not be able to handle different
output_reference values for a given named component but the IORT kernel
layer should still report the IORT mappings as reported by firmware) but
current code in iort_node_get_id() fails to use the index function
parameter to return the correct output_reference value (ie it always
returns the output_reference value of the first entry in the mapping
array whilst using the index correctly to retrieve the id value from the
respective entry).
|----------------------|
| named component |
|----------------------|
| map entry[0] |
|----------------------|
| id value |
| output_reference----------------> eg SMMU 1
|----------------------|
| map entry[1] |
|----------------------|
| id value |
| output_reference----------------> eg SMMU 2
|----------------------|
.
.
.
|----------------------|
| map entry[N] |
|----------------------|
| id value |
| output_reference----------------> eg SMMU 1
|----------------------|
Consequently the iort_node_get_id() function always returns the IORT
node pointed at by the output_reference value of the first named
component mapping array entry, irrespective of the index parameter,
which is a bug.
Update the map array entry pointer computation in iort_node_get_id() to
take into account the index value, fixing the issue.

When resuming, it's possible for the following scenario to occur:
* iwl_pci_resume() enables the RF-kill interrupt
* iwl_pci_resume() reads the RF-kill state (e.g. to 'radio enabled')
* RF_KILL interrupt triggers, and iwl_pcie_irq_handler() reads the
state, now 'radio disabled', and acquires the &trans_pcie->mutex.
* iwl_pcie_irq_handler() further calls iwl_trans_pcie_rf_kill() to
indicate to the higher layers that the radio is now disabled (and
stops the device while at it)
* iwl_pcie_irq_handler() drops the mutex
* iwl_pci_resume() continues, acquires the mutex and calls the higher
layers to indicate that the radio is enabled.
At this point, the device is stopped but the higher layers think it's
available, and can call deeply into the driver to try to enable it.
However, this will fail since the device is actually disabled.
