Currently we set all skbs with CHECKSUM_UNNECESSARY, even
those whose protocol we don't know. This patch just
add the CHECKSUM_COMPLETE tag for non TCP/UDP packets.

At least one board using the FEC driver does not have a conventional
PHY attached to it, it is directly connected to a somewhat simple
ethernet switch (the board is the SnapGear/LITE, and the attached
4-port ethernet switch is a RealTek RTL8305). This switch does not
present the usual register interface of a PHY, it presents nothing.
So a PHY scan will find nothing - it finds ID's of 0 for each PHY
on the attached MII bus.
After the FEC driver was changed to use phylib for supporting PHYs
it no longer works on this particular board/switch setup.
Add code support to use a fixed phy if no PHY is found on the MII bus.
This is based on the way the cpmac.c driver solved this same problem.

commit 511d22247be7 (tg3: 64 bit stats on all arches), overlooked the
rx_dropped accounting.
We use a full "struct rtnl_link_stats64" to hold rx_dropped value, but
forgot to report it in tg3_get_stats64().
Use an "unsigned long" instead to shrink "struct tg3" by 176 bytes, and
report this value to stats readers.
Increment rx_dropped counter for oversized frames.

Stanse found that i2400m_rx frees skb, but still uses skb->len even
though it has skb_len defined. So use skb_len properly in the code.
And also define it unsinged int rather than size_t to solve
compilation warnings.

Stanse found that ia_init_one locks a spinlock and inside of that it
calls ia_start which calls:
* request_irq
* tx_init which does kmalloc(GFP_KERNEL)
Both of them can thus sleep and result in a deadlock. I don't see a
reason to have a per-device spinlock there which is used only there
and inited right before the lock location. So remove it completely.

Stanse found we do in console_show:

return skb->len;
which is not good. Fix that by remembering the len and use it in the

with hardware slow in negotiation, the system did freeze
while trying to mount root on nfs at boot time.
the link state has not been initialised so network stack
tried to start transmission right away. this caused instant
retries, as the driver solely stated business upon link down,
rendering the system unusable.
notify carrier off initially to prevent transmission until
phylib will report link up.

Commit 0793448 "DMAENGINE: generic channel status v2" changed the interface for
how dma channel progress is retrieved. It inadvertently exported an internal
helper function ioat_tx_status() instead of ioat_dma_tx_status(). The latter
polls the hardware to get the latest completion state, while the helper just
evaluates the current state without touching hardware. The effect is that we
end up waiting for completion timeouts or descriptor allocation errors before
the completion state is updated.
iperf (before fix):
[SUM] 0.0-41.3 sec 364 MBytes 73.9 Mbits/sec
iperf (after fix):
[SUM] 0.0- 4.5 sec 499 MBytes 940 Mbits/sec
This is a regression starting with 2.6.35.

We should not allocate any object into unmappable vram if we
have no means to access them which on all GPU means having the
CP running and on newer GPU having the blit utility working.
This patch limit the vram allocation to visible vram until
we have acceleration up and running.
Note that it's more than unlikely that we run into any issue
related to that as when acceleration is not woring userspace
should allocate any object in vram beside front buffer which
should fit in visible vram.
V2 use real_vram_size as mc_vram_size could be bigger than
the actual amount of vram

The undocumented interface we're using for reading CPU power seems to be
overreporting power. Until we figure out how to correct it, disable CPU
turbo and power reporting to be safe. This will keep the CPU within default
limits and still allow us to increase GPU frequency as needed.

Both when polling the current turbo status (in poll_turbo_status mode)
and when handling thermal events (in ips_irq_handler) the current status
of GPU turbo is updated to match the hardware status. However if during
driver initialisation we were unable aquire linkage to the i915 driver
enabling GPU turbo will lead to an oops on the first attempt to determine
GPU busy status.
Ensure that we do not enable GPU turbo unless we have driver linkage.

The patch is to create ips_adjust thread before ips_monitor begins
to run because the latter will kthread_stop() or wake up the former
via ips->adjust pointer. Without this change, it is possible that
ips->adjust is NULL when kthread_stop() or wake_up_process() is
called in ips_monitor().

Currently the pressure range in Cintiq 21UX2 is limited to half of the
supported. This patch fixes the problem.

setup.phone and setup.eazmsn are 32 character buffers.
rcvmsg.msg_data.byte_array is a 48 character buffer.
sc_adapter[card]->channel[rcvmsg.phy_link_no - 1].dn is 50 chars.
The rcvmsg struct comes from the memcpy_fromio() in receivemessage().
I guess that means it's data off the wire. I'm not very familiar with
this code but I don't see any reason to assume these strings are NULL
terminated.
Also it's weird that "dn" in a 50 character buffer but we only seem to
use 32 characters. In drivers/isdn/sc/scioc.h, "dn" is only a 49
character buffer. So potentially there is still an issue there.
The important thing for now is to prevent the memory corruption.

bonding: Bond creation failed.
It happens because a user space writer to bond_master can try to
register an already existing bond interface name. Fix it by teaching
bond_create to check for the existance of devices with that name first
in cases where a non-NULL name parameter has been passed in

Skge devices installed on some Gigabyte motherboards are not able to
perform 64 dma correctly due to board PCI implementation, so limit
DMA to 32bit if such boards are detected.

Since 'select' ignores dependencies, drivers that select INET_LRO must
depend on INET. This fixes the broken configuration reported in
<http://article.gmane.org/gmane.linux.kernel/825646>.

The brightness control hotkey don't work with Vista compatibility
because the MSI GX723 includes an infinite while loop in DSDT when
brightness control hotkey pressed.
The MSI GX723 uses Nvidia video. Perhaps the loop is specific
to the Nvidia Vista driver...
This patch should be reverted once nouveau grows support
to call the ACPI NVIF method.

| ACPI: processor: driver doesn't need to evaluate _PDC
|
| Now that the early _PDC evaluation path knows how to correctly
| evaluate _PDC on only physically present processors, there's no
| need for the processor driver to evaluate it later when it loads.
|
| To cover the hotplug case, push _PDC evaluation down into the
| hotplug paths.
only cpu with Processor Statement get processed with _PDC
If bios is using Device object instead of Processor statement.
SSDTs for Pstate/Cstate/Tstate can not be loaded dynamically.
Need to try to scan ACPI0007 in addition to Processor.
That commit is between 2.6.34-rc1 and 2.6.34-rc2, so stable tree for 2.6.34+
need this patch.

drm/i915: Prevent module unload to avoid random memory corruption

| | | | | | | | | | | | |
The i915 driver has quite a few module unload bugs, the known ones at
least have fixes that are targeting 2.6.37. However, in order to
maintain a stable kernel, we should prevent this known random memory
corruption following driver unload. This should have very low impact on
normal users who are unlikely to need to unload the i915 driver.
