In an embedded system the matrix_keypad driver might be used to
interface with an external control panel and not an actual keyboard.
On the control panel some of the keys could be used to turn on/off
various functions. If key autorepeat is enabled this causes the
function to quickly toggle between the on and off states and makes
operation difficult.
Add an option in the platform-specific data to disable the key
autorepeat.

By default, ACPI resource conflict messages are logged at level
KERN_ERR. This is a rather high level for a message that is more a
warning than an indication of a real kernel error. Also, KERN_ERR level
messages can appear over some boot splash screens, and this message is
not serious enough to warrant such treatment. Thus, the log level has
been reduced to KERN_WARNING.
[lenb changed to KERN_WARNING rather than all the way to KERN_INFO]

- pcmcia_align() used a "start" variable twice. That's obviously a bad

- pcmcia_common_resource() needs the current "start" parameter being

- pcmcia_common_resource() doesn't use the size and align parameters,

The ACPI spec (sec 6.4.3.5 in v4.0) requires that for Address Space Resource
Descriptors, _LEN <= _MAX - _MIN + 1 in all cases, but there are BIOSes that
violate this. We experimentally determined that Windows truncates the
resource so it doesn't extend past _MAX, so let's do the same thing in
Linux.

Previously, we assumed the only Device object immediately below the root
was the \_SB Scope (which the ACPI CA treats as a Device), so we forced
the HID of all such objects to ACPI_BUS_HID ("LNXSYBUS").
However, there are DSDTs that supply root-level Device objects with _HIDs.
This patch makes us pay attention to those _HIDs and only add the synthetic
ACPI_BUS_HID for root-level objects that do not supply their own _HID.
For example, this DSDT: https://bugzilla.kernel.org/show_bug.cgi?id=15605
contains:
Scope (_SB) {
...
}
Device (AMW0) {
Name (_HID, EisaId ("PNP0C14"))
...
}
and we should use "PNP0C14" for the AMW0 device, not "LNXSYBUS".

We used to free all the Tx queues memory when interface is brought
down and reallocate them again in interface up. This requires
order-4 allocation for txq->cmd[]. In situations like s2ram, this
usually leads to allocation failure in the memory subsystem. The
patch fixed this problem by allocating the Tx queues memory only at
the first time. Later iwl_down/iwl_up only initialize but don't
free and reallocate them. The memory is freed at the device removal
time. BTW, we have already done this for the Rx queue.

When collecting tx data for non-aggregation packets in rate scaling, if
the tx data matches "other table", it still uses current table to update
the stats and calculate average throughput in function rs_collect_tx_data().
This can mess up the rate scaling data structure and cause a kernel panic
in a BUG_ON statement in rs_rate_scale_perform().
To fix this bug, we pass table pointer instead of window pointer (pointed
to by table pointer) to function rs_collect_tx_data() so that the table
being used is consistent.
