The SSB PCIcore code reused the IO resource fixup code from the original
2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack
for doing PCI IO resource configuration back then (the boot loader
doesn't configure PCI devices on this platform).
However, this code is no longer necessary since the kernel now can do
PCI resource management fine all by itself, so remove the old code.
When removing the code, it becomes obvious that the mem_offset setting
in the PCIcore driver was wrong, however this was masked by the fixup
code before, except in a few cases involving yenta_socket. For BCM47xx,
the correct offset is 0, and since this is the only device using PCIcore
in host mode, the offset can simply be removed unconditionally.

On AR7, we already redefine PHYS_OFFSET to match the system specifities, it
is however not sufficient when unsing dma_{map,unmap}_single, specifically
in the ethernet driver, we must also adjust CAC_ADDR and UNCAC_ADDR for DMA
to work correctly. This patch fixes the following issue, seen in cpmac_open:

Like x86 did in arch/x86/kernel/{process_32.c,process_64.c}, also don't
trace irqsoff for idle.
If there's no useful work to be done, we don't care about the irqsoff
duration. If we trace the idle process, the max duration of irqsoff will
be the idle time and make the irqsoff tracer useless.

This reverts commit 6070a4a928f8c92b9fae7d6717ebbb05f425d6b2.
The quirk for this SDVO device on IBM specific board is just a hack
in old code which showed the broken multifunction SDVO support in
the driver. Multifunction SDVO patch provided the right fix for it.

With new intel_encoder/intel_connector structure change, each supported
connector type on SDVO device will be created as a new 'intel_connector',
and all attached to one 'intel_encoder' for its SDVO port.
The SDVO encoder will handle SDVO protocol stuff, and each connector does
its own part of work now, like detection is only to check if current active
output is itself, etc.
Update since last submit:
- Fixed SDVO TV property creation failure by incorrect set target output call

Cougarpoint is the new PCH for Sandybridge CPU. This one resolves the
chipset change for display pipeline compared to previous Ibexpeak PCH.
Sandybridge/Cougarpoint has different FDI training parameters, so this also
makes seperate FDI training functions for IBX and CPT. Other change includes
new transcoder DPLL select function to set which DPLL for transcoder to pick
up.
And with another new transcoder C introduced in Cougarpoint, each connector
has new transcoder select bits. This one adds that change to light up VGA.

Arnaud Giersch reports that NFSv4 locking is broken when we hold a
delegation since commit 8e469ebd6dc32cbaf620e134d79f740bf0ebab79 (NFSv4:
Don't allow posix locking against servers that don't support it).
According to Arnaud, the lock succeeds the first time he opens the file
(since we cannot do a delegated open) but then fails after we start using
delegated opens.
The following patch fixes it by ensuring that locking behaviour is
governed by a per-filesystem capability flag that is initially set, but
gets cleared if the server ever returns an OPEN without the
NFS4_OPEN_RESULT_LOCKTYPE_POSIX flag being set.
