CMD646 corrupts data on concurrent transfers on both channels when IDE SSD is
connected to one of the channels.
Setup that demonstrates this hardware bug: Ultra 5, onboard CMD646, rev 3.
/dev/hda is 8GB Seagate ST38410A in MWDMA2
/dev/hdd is 32GB SSD SiliconHardDisk in MWDMA2
- When reading /dev/hdd (for example with dd or fsck), reads from /dev/hda
are corrupted, there are twiddled single bits 1->0 and some full 32-bit
words corrupted, sometimes commands fail (which switches /dev/hda to
PIO mode but the corruptions happen even in PIO).
- Reads from /dev/hdd don't seem to be corrupted (i.e. fsck passes fine).
- When I connected normal rotating harddisk to /dev/hdd, there was no
corruption, so the corruption is something specific to SSD.
- I tried the same setup on a PCI card with CMD649 and saw no corruption.
This patch serializes the operation for CMD646 and 643 (I didn't test
CMD643 but it may have the same hw bug too because it's earlier design).
CMD649 is good. I don't know anything about CMD 648.

I found that the current version of drivers/net/usb/dm9601.c can be used to
successfully drive a low-power, low-cost network adapter with USB ID
0a46:9000, based on a DM9000E chipset. As no device with this ID is yet
present in the kernel, I have created a patch that adds support for the device
to the dm9601 driver.
Created and tested against linux-2.6.32-rc5.

In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.
If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.
Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

Commit f68d24082e22ccee3077d11aeb6dc5354f0ca7f1
in 2.6.32-rc1 broke requesting IRQs for per-VQ MSI-X vectors:
- vector number was used instead of the vector itself
- we try to request an IRQ for VQ which does not
have a callback handler
This is a regression that causes warnings in kernel log,
potentially lower performance as we need to scan vq list,
and might cause system failure if the interrupt
requested is in fact needed by another system.
This was not noticed earlier because in most cases
we were falling back on shared interrupt for all vqs.
The warnings often look like this:
virtio-pci 0000:00:03.0: irq 26 for MSI/MSI-X
virtio-pci 0000:00:03.0: irq 27 for MSI/MSI-X
virtio-pci 0000:00:03.0: irq 28 for MSI/MSI-X

virtio net used to unlink skbs from send queues on error,
but ever since 48925e372f04f5e35fec6269127c62b2c71ab794
we do not do this. This causes guest data corruption and crashes
with vhost since net core can requeue the skb or free it without
it being taken off the list.
This patch fixes this by queueing the skb after successful
transmit.

Limiting the pll output range is a good thing generally as
it limits the number of possible pll combinations for a given
frequency presumably to the ones that work best on each card.
That's why the limits are in the bios tables. However, certain
duallink DVI monitors seem to like pll combinations that would
be limited by this at least on pre-DCE 3.0 r6xx hardware. This
might need to be adjusted per family or per clock range in the
future.

"b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported
in Bugzilla No. 14181; however, it introduced a new bug. Whenever the
radio switch was turned off, it was necessary to unload and reload
the driver for it to recognize the switch again.
This patch fixes both the original bug in #14181 and the bug introduced by
the previous patch. It must be stated, however, that if there is a BCM4306/3
with an rfkill switch (not yet proven), then the driver will need an
unload/reload cycle to turn the device back on.

Be more careful about the state of pointers during tear-down.
The "pppoe_dev" field can only be looked at safely while holding socket locks.
This subsequently allows for the flush_lock to be killed.
We depend on the PPPOX_CONNECTED state to tell us that that those fields are
valid, so whoever clears that state (pppox_unbind_sock()) is responsible for
the dev_put() call.
We also have to ensure that we delete_item() on all sockets before they are
cleaned up.
The need for these changes has been exposed by scenarios wherein namespace
bindings of ethernet devices change while there are ongoing PPPoE sessions,
which resulted in oopses due to unusual socket connection termination paths,
exposing these issues.

PCH-based parts (82577/82578) and some ICH8-based parts (82566) need to
hold the swflag (sw/fw/hw hardware semaphore) over consecutive PHY accesses
in order to perform sw-driven PHY configuration during initialization to
workaround known hardware issues (see follow-on patch). This patch
provides new PHY read/write functions (and function pointers) that will
allow accessing the PHY registers assuming the swflag has already been
acquired. The actual PHY register access code has moved into helper
functions that are called with a flag indicating whether or not the swflag
has already been acquired and acquires/releases it if not.
The functions called from within the updated PHY access functions had to be
updated to assume the swflag was already acquired, and other functions that
called those functions were also updated to acquire/release the swflag.

Accesses to NVM and PHY/CSR registers on ICHx/PCH-based parts are protected
from concurrent accesses with a mutex that is acquired when the access is
initiated and released when the access has completed. However, the two
types of accesses should not be protected by the same mutex because the
driver may have to access the NVM while already holding the mutex over
several consecutive PHY/CSR accesses which would result in livelock.

In some conditions (e.g. when AMT is enabled on the system), it is possible
to take an extended period of time to for the driver to acquire the sw/fw/hw
hardware semaphore used to protect against concurrent access of a shared
resource (e.g. PHY registers). This could cause PHY registers to not get
configured properly resulting in link issues.

Changing ring sizes while the interface was down was causing a double
allocation of the receive and transmit rings. This issue is amplified when
there are multiple rings enabled. To prevent this we need to add an
additional check which will just update the ring counts when the interface
is not up and skip the allocation steps.

This patch adds a new flag to the drmWaitVblank ioctl, which asks the drm
to return immediately and notify userspace when the specified vblank sequence
happens by sending an event back on the drm fd.
The event mechanism works with the other flags supported by the ioctls,
specifically, the vblank sequence can be specified relatively or absolutely,
and works for primary and seconday crtc.
The signal field of the vblank request is used to provide user data,
which will be sent back to user space in the vblank event.

The *_HIGH regs are reversed. The secondary ones are in the
primary block and vice versa.
We currently only use a 32 bit internal address, so these are
0 for now.

Where supported use ulMinPixelClockPLL_Output rather than
usMinPixelClockPLL_Output for pll_out_min. This seems to
improve pll selection on some boards.
