This fixes hangs on 855-class hardware by avoiding double attachment of the
driver due to the stub second head device having the same pci id as the real
device.

Other DRM drivers probably want this treatment as well, but I'm applying it
just to this one for safety. But we should clean up the drm_pciids.h mess
now so that each driver has its own pci id list header in its own directory.
Lets do that in the next release.

ehc->last_reset is used to ensure that resets are not issued too
close to each other.  It's initialized to jiffies minus one minute
on EH entry.  However, when new links are initialized after PMP is
probed, new links have zero for this timestamp resulting in long wait
depending on the current jiffies.

This patch makes last_set considered iff ATA_EHI_DID_RESET is set, in
which case last_reset is always initialized.  As an added precaution,
WARN_ON() is added so that warning is printed if last_reset is
in future.

Now that the radeon driver has suspend/resume functions, it needs to map its
registers at load time or it will likely crash if a suspend operation occurs
before the driver has been initialized.

This patch moves the register mapping code from firstopen to load and makes
the mapping into a _DRM_DRIVER one so that the core won't remove it at
lastclose time.

When userland detected that this ioctl was supported (by version number check),
it used it in a racy way -- dispatch delayed swap, wait for vblank, continue
rendering. As there was no mechanism for it to wait for the swap to finish,
sometimes it would render before the swap and garbage would be displayed on
the screen.

By removing the ioctl and returning -EINVAL, userland returns to its previous,
correct rendering path of waiting for a vblank then dispatching a swap.  The
only path that could have used this ioctl correctly was page flipping, which
relied on only one client running and emitting wait-for-vblank-before-rendering
in the command stream.  That path also falls back correctly, at the performance
cost of not being able to queue up rendering before the flip occurs.

Before commit b6c40d68 ("net: only
invoke dev->change_rx_flags when device is UP"), the dsa driver could
sort-of get away with only fiddling with the master interface's
allmulti/promisc counts in ->change_rx_flags() and not touching them
in ->open() or ->stop().  After this commit (note that it was merged
almost simultaneously with the dsa patches, which is why this wasn't
caught initially), the breakage that was already there became more
apparent.

Since it makes no sense to keep the master interface's allmulti or
promisc count pinned for a slave interface that is down, copy the vlan
driver's sync logic (which does exactly what we want) over to dsa to
fix this.

This patch reverts the following three commits which convert libata to
use block layer tagging.

 43a49cbd
 e013e13b
 2fca5ccf

Although using block layer tagging is the right direction, due to the
tight coupling among tag number, data structure allocation and
hardware command slot allocation, libata doesn't work correctly with
the current conversion.

The biggest problem is guaranteeing that tag 0 is always used for
non-NCQ commands.  Due to the way blk-tag is implemented and how SCSI
starts and finishes requests, such guarantee can't be made.  I'm not
sure whether this would actually break any low level driver but it
doesn't look like a good idea to break such assumption given the
frailty of ATA controllers.

So, for the time being, keep using the old dumb in-libata qc
allocation.
