[netdrvr] Drivers should not set IFF_* flag themselves
Some hardware set promisc when they are requested to set IFF_ALLMULTI flag.
It's ok, but if drivers set IFF_PROMISC flag when they set promisc,
it will broken upper layer handle for promisc and allmulti.
In addition, drivers can use their own hardware programming to make it.
So do not allow drivers to set IFF_* flags.
This is a general driver fix, so I didn't split it to pieces and send
to specific driver maintainers.

dm9000: Support MAC address setting through platform data.
The dm9000 driver reads the chip's MAC address from the attached EEPROM. When

reading the address from the chip.
This patch lets platform code set the desired MAC address through platform

Based upon original patch by Herbert Xu, which contained
the following problem description:
--------------------
When the forward delay is set to zero, we still delay the setting
of the forwarding state by one or possibly two timers depending
on whether STP is enabled. This could either turn out to be
instantaneous, or horribly slow depending on the load of the
machine.
As there is nothing preventing us from enabling forwarding straight
away, this patch eliminates this potential delay by executing the
code directly if the forward delay is zero.
The effect of this problem is that immediately after the carrier
comes on a port, the bridge will drop all packets received from
that port until it enters forwarding mode, thus causing unnecessary
packet loss.
Note that this patch doesn't fully remove the delay due to the
link watcher. We should also check the carrier state when we
are about to drop an incoming packet because the port is disabled.
But that's for another patch.
--------------------
This version of the fix takes a different approach, in that
it just does the state change directly.

radeon: misc corrections

I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.
1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
and the XORG video driver differ. I've made the kernel
match what XORG is using.
2) In radeonfb_engine_reset() we have top-level code structure
that roughly looks like:
if (family is 300, 350, or V350)
do this;
else
do that;
...
if (family is NOT 300, OR
family is NOT 350, OR
family is NOT V350)
do another thing;
this last conditional makes no sense, is always true,
and obviously was likely meant to be "family is NOT
300, 350, or V350". So I've made the code match the
intent.

relay: fix "full buffer with exactly full last subbuffer" accounting problem
In relay's current read implementation, if the buffer is completely full
but hasn't triggered the buffer-full condition (i.e. the last write
didn't cross the subbuffer boundary) and the last subbuffer is exactly
full, the subbuffer accounting code erroneously finds nothing available.
This patch fixes the problem.

spi: new orion_spi driver
This adds an SPI driver for the SPI controller found in various Marvell
Orion ARM SoCs. It currently supports only one slave, which must use SPI
mode 0.
curr_queue is a local variable in a for loop, and it's being initialized
at the start of each loop. So any assignment at the end of the loop is
pointless.

Fix USB storage hang on command abort
Okay, I found the cause of the hang. It is a simple bug in the USB
scatter-gather library, caused by changes added in response to the S-G
chaining modification.
This patch (as1125) fixes a bug in the USB scatter-gather library.
Early exit from the S-G initialization loop does not reset the count of
outstanding URBs.

cdrom: don't check CDC_PLAY_AUDIO in cdrom_count_tracks()
According to MMC-3 (or any later versions) READ TOCs are mandatory
commands and have nothing to do with CDC_PLAY_AUDIO. I have no idea why
the check was put there in the first place but it now only breaks
automatic actions on certain drives.
Note that this test was only effective when ide-cdrom was being used
as sr didn't mask CDC_PLAY_AUDIO according to the capabilities.

ide-cd: fix endianity for the error message in cdrom_read_capacity
Aesthetic regards aside, commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667
still leaves a bug in the error message, because it uses the unconverted
big-endian value for printk.
Fix this by using a local variable in machine byte order. The result is
correct, more readable, and also produces slightly shorter code on i386.

The guilty commit turned out to be 08da591e14cf87247ec09b17c350235157a92fc3
("ide: add ide_device_{get,put}() helpers"). ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.
Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.
v2:
Brown paper bag time. In v1 cd->drive was referenced after dropping last
reference on cd object (which could result in OOPS in ide_device_put() as
reported/debugged by Mariusz Kozlowski). Fix it by caching cd->drive in
the local variable (fix other device drivers too).
