When runtime PM for platform_bus was added, it allowed for platforms
to customize the runtime PM methods since they are defined as weak
symbols.
This patch allows platforms to also extend the system PM methods with
custom hooks so runtime PM and system PM extensions can be managed
together by custom platform-specific code.

kasprintf combines kmalloc and sprintf, and takes care of the size
calculation itself.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression a,flag;
expression list args;
statement S;
@@
a =
- \(kmalloc\|kzalloc\)(...,flag)
+ kasprintf(flag,args)
<... when != a
if (a == NULL || ...) S
...>
- sprintf(a,args);

This patch (as1351) removes an unnecessary and unwanted assignment
from device_initialize(). The wakeup flags are set to 0 along with
everything else when the device structure is allocated, so we don't
need to do it again. Furthermore, the subsystem might already have
set these flags to their correct values; we don't want to override it.

This patch fix a potential race condition in the driver_bound() function
in the file driver/base/dd.c.
The broadcast of the BUS_NOTIFY_BOUND_DRIVER notifier should be done
after adding the new device to the driver list. Otherwise notifier
listener will fail if they use functions like usb_find_interface().
The patch is against kernel 2.6.33. Please merge it.

The messages from _request_firmware() informing that firmware is
being requested or built-in firmware is going to be used are printed
at KERN_INFO, which produces lots of noise on systems with huge
numbers of AMD CPUs. Reduce the level of these messages to
KERN_DEBUG to get rid of that noise.

Of the three uses of kref_set in the kernel:
One really should be kref_put as the code is letting go of a
reference,
Two really should be kref_init because the kref is being
initialised.
This suggests that making kref_set available encourages bad code.
So fix the three uses and remove kref_set completely.

fix memory leak introduced by the patch 6e03a201bbe:
firmware: speed up request_firmware()
1. vfree won't release pages there were allocated explicitly and mapped
using vmap. The memory has to be vunmap-ed and the pages needs
to be freed explicitly
2. page array is moved into the 'struct
firmware' so that we can free it from release_firmware()
and not only in fw_dev_release()
The fix doesn't break the firmware load speed.

Fix a problem in early versions of the FPGA IP.
In certain situations the IP reports that the FIFO is empty, but a byte is
still clocked out. If a flush is done at that point the currently clocked
byte is canceled.
This causes incompatibilities with the upper layers when a port is closed,
it waits until the FIFO is empty and then closes the port. During close
the FIFO is flushed -> the last byte is not sent properly.
Now the FIFO is only flushed if it is reported to be non-empty. Which
makes the currently clocked out byte to finish.

Byte accesses for I/O devices in Xilinx IP is going to be less
desired in the future such that the driver is being changed to
use 32 bit accesses.
This change facilitates using the uartlite IP over a PCIe bus

Add an implementation of GSM 0710 MUX. The implementation currently supports
- Basic and advanced framing (as either end of the link)
- UI or UIH data frames
- Adaption layer 1-4 (1 and 2 via tty, 3 and 4 as skbuff lists)
- Modem and control messages including the correct retry process
- Flow control
and exposes the MUX channels as a set of virtual tty devices including modem
signals. This is an experimental driver.
