873a69a358 gigaset: prune use of tty_buffer_request_room
Calling tty_buffer_request_room() before tty_insert_flip_string()
is unnecessary, costs CPU and for big buffers can mess up the
multi-page allocation avoidance.

3a0a3a6b92 gigaset: correct clearing of at_state strings on RING
In RING handling, clear the table of received parameter strings in

bc35b4e347 gigaset: avoid registering CAPI driver more than once
Registering/unregistering the Gigaset CAPI driver when a device is
connected/disconnected causes an Oops when disconnecting two Gigaset
devices in a row, because the same capi_driver structure gets
unregistered twice. Fix by making driver registration/unregistration
a separate operation (empty in the ISDN4Linux case) called when the
main module is loaded/unloaded.

8b4017d8c1 i4l: silence compiler warnings for array access in Eicon DIVA ISDN driver
When compiling this driver, the compiler throws the following warnings:

drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds

This arises from the particular semantics the driver is using to write to
the nlc array (static byte[256]).  The array has a length in byte 0
followed by a T30_INFO struct starting at byte 1.

The T30_INFO struct has a number of variable length strings after the
station_id entry, which cannot be explicitly defined in the struct and the
driver accesses them with an array index to station_id beyond the length
of station_id.

This patch merely changes the semantics that the driver uses to access the
entries after the station_id entry to use the original 256 byte nlc array
taking the offset and length of the station_id entry to calculate where to
write in the array, thereby silencing the warning.

Update of fp->tx_bd_cons in bnx2x_tx_int() is not protected by lock, but

netif_tx_stop_queue(), netif_tx_queue_stopped(), fp->tx_bd_cons = bd_cons

Modify the driver to use the dma_{map, unmap}_single() APIs

tree.

are a good starting spot, so let's just rename that file and

0131aa3dd7 ACPI: processor: mv processor_core.c processor_driver.c
The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.

The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.

Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c

Next step will re-create processor_core.c and cherry-pick out
the static bits.

d060705091 acpiphp: Execute ACPI _REG method for hotadded devices
Per ACPI spec, _ERG method should be executed before device driver
gets control for hotpluged device. Firmware might do some configuration
there. See http://bugzilla.kernel.org/show_bug.cgi?id=10805. In this
machine, _REG method of docked device will configure cardbus bridge.

70287db87c ACPI video: Be more liberal in validating _BQC behaviour
Right now, if _BQC returns a value we don't understand we immediately
invalidate it. Change this behaviour so we only invalidate it if it
continues to give an invalid answer after we've already set a brightness.
