Every ring seems to have the concept of read and
write pointers. Make the register offset variable
so we can use the functions for different types of rings.

This reverts commit eb1711bb94991e93669c5a1b5f84f11be2d51ea1.
It blows up the i915 seqno tracking, resulting in the
BUG_ON(seqno == 0);
in i915_wait_request() triggering, which will cause lock-ups.

This fixes a Data bus error on some SoCs. The first fix for this
problem did not solve it on all devices.
commit 6ae8ec27868bfdbb815287bee8146acbefaee867
Author: Rafał Miłecki <zajec5@gmail.com>
Date: Tue Jul 5 17:25:32 2011 +0200
ssb: fix init regression of hostmode PCI core
In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is
accessed, but the sprom only exists when the ssb bus is connected over
a PCI bus to the rest of the system and not when the SSB Bus is the
main system bus. SoCs sometimes have a PCI host controller and there
this code will not be executed, but there are some old SoCs with an PCI
controller in client mode around and ssb_pcicore_fix_sprom_core_index()
should not be called on these devices too. The PCI controller on these
devices are unused, but without this fix it results in an Data bus
error when it gets initialized.

The code for setting the address of the internal TBI PHY was
convoluted enough without a maze of ifdefs. Clean it up a bit
so we allow the logic to fail down to -ENODEV at the end of
the if/else ladder, rather than using ifdefs to repeat the same
failure code over and over.
Also, remove the support for the auto-configuration. I'm not aware of
anyone using it, and it ends up using the bus mutex before it's been
initialized.

The pdev->id is used in several places for different purpose. All
these uses assume it's always the id of fec device which is >= 0.
However this is only true for non-DT case. When DT plays, pdev->id
is always -1, which will break these pdev->id users.
Instead of fixing all these users one by one, this patch introduces
a new member 'dev_id' to 'struct fec_enet_private' for holding the
correct fec device id, and replaces all the existing uses of pdev->id
with this dev_id.

This adds a default setting for semaphores parameter, and enables
semaphores by default on IVB.
For now, as semaphores interaction with VTd causes random issues on
SNB, we do not enable them by default. But they can still be enabled
via the semaphores=1 kernel parameter.
v2: enables semaphores on SNB when IO remapping is disabled, with base
on Keith Packard patch.

We were checking whether the supplied edid matched the connector it was
read from. We do this in case a DDC read returns an EDID for another
device on a multifunction or otherwise interesting card. However, we
failed to include LVDS as a digital device and so rejecting an otherwise
valid EDID.
Fixes the detection of the secondary SDVO LVDS panel on the Libretto
W105.

This prevents an in-kernel division by zero which happens when we are
asking for i915_chipset_val too quickly, or within a race condition
between the power monitoring thread and userspace accesses via debugfs.
The issue can be reproduced easily via the following command:
while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; done
This is particularly dangerous because it can be triggered by
a non-privileged user by just reading the debugfs entry.
This issue was also found independently by Konstantin Belousov
<kostikbel@gmail.com>, who proposed a similar patch.

For i945 and earlier chips, the backlight frequency value had the low
bit (of 16) fixed to zero. The Pineview code path handled this by just
exposing the backlight range as 15 bits while other chips had the
backlight range limited to 0 .. 0xfffe.
This patch makes everyone take the pineview code path, providing 15
bits of backlight duty cycle range which seems more than sufficient to
me.
Daniel Mack reported that writing 1 to bit 0 of the duty cycle
register was causing problems on his Samsung X20 notebook, even when
the duty cycle value was less than the maximum backlight value. (He
tried a value of 29749 with max_brightness of 29750). This patch never
writes a '1' to that bit.

The Ivybridge eDP control register looks like a cross between a
Cougarpoint PCH DP control register and a Sandybridge eDP control
register.
Where things trivially match, share the code. Where there are any
tricky bits, just split things out into two obviously separate code paths.

On IVB C0+ with newer BIOSes, the forcewake handshake has changed. There's
now a bitfield for different driver components to keep the GT powered
on. On Linux, we centralize forcewake handling in one place, so we
still just need a single bit, but we need to use the new registers if MT
forcewake is enabled.
This needs testing on affected machines. Please reply with your
tested-by if you had problems after a BIOS upgrade and this patch fixes
them.
v2: force MT mode. shift by 16
v3: set MT force wake bits then check ECOBUS

The old PowerMac swim3 driver has some "interesting" locking issues,
using a private lock and failing to lock the queue before completing
requests, which triggered WARN_ONs among others.
This rips out the private lock, makes everything operate under the
block queue lock, and generally makes things simpler.
We used to also share a queue between the two possible instances which
was problematic since we might pick the wrong controller in some cases,
so make the queue and the current request per-instance and use
queuedata to point to our private data which is a lot cleaner.
We still share the queue lock but then, it's nearly impossible to actually
use 2 swim3's simultaneously: one would need to have a Wallstreet
PowerBook, the only machine afaik with two of these on the motherboard,
and populate both hotswap bays with a floppy drive (the machine ships
only with one), so nobody cares...
While at it, add a little fix to clear up stale interrupts when loading
the driver or plugging a floppy drive in a bay.
