We only add/remove crtcs at driver load, you cannot remove when
the GPU is running a CS packet since the fd is open, when
GPU hotplugging on radeons actually is needed all this locking
needs a review and I've started re-working kms core locking to deal
with this better. But for now avoid long delays in CS processing when
hotplug detect is happening in a different thread.

this fixes a regression introduced with hotplug detection.

On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS,
which will break some setups.

This patch also removes the different ordering of shadow methods for
pre-nv50 chipsets.  The reason for the different ordering was paranoia,
but it should hopefully be OK to try shadowing PRAMIN first.

This fixes a regression caused by b2ea4aa6
due to the way shared ddc with multiple digital connectors was handled.

You generally have two cases where DDC lines are shared:
- HDMI + VGA
- HDMI + DVI-D

HDMI + VGA is easy to deal with because you can check the EDID for the
to see if the attached monitor is digital.  A shared DDC line with two
digital connectors is more complex.  You can't use the hdmi bits in the
EDID since they may not be there with DVI<->HDMI adapters.  In this case
all we can do is check the HPD pins to see which is connected as we have
no way of knowing using the EDID.

A lot of 945GMs have had stability issues for a long time, this manifested as X hangs, blitter engine hangs, and lots of crashes.

one such report is at:
https://bugs.freedesktop.org/show_bug.cgi?id=20560

along with numerous distro bugzillas.

This only took a week of digging and hair ripping to figure out.

Tracked down and tested on a 945GM Lenovo T60,
previously running
x11perf -copypixwin500
or
x11perf -copywinpix500
repeatedly would cause the GPU to wedge within 4 or 5 tries, with random busy bits set.

After this patch no hangs were observed.

The asics in question have the following requirements with regard to
their gart setups:

1. The GART aperture size has to be in the form of 2^X bytes, where X is from 25 to 31
2. The GART aperture MC base has to be aligned to a boundary equal to the size of the
aperture.
3. The GART page table has to be aligned to the boundary equal to the size of the table.
4. The GART page table size is: table_entry_size * (aperture_size / page_size)
5. The GART page table has to be allocated in non-paged, non-cached, contiguous system
memory.

This patch takes care 2.  The rest should already be handled properly.

  ARM: reduce defconfigs

This is a big change, but results in no loss of information, despite us
losing almost 200k lines:

 177 files changed, 652 insertions(+), 194157 deletions(-)

and Grant Likely thinks powerpc can also use the same reduction

The python script that did the reduction looks like this:

    os.environ['KCONFIG_NOTIMESTAMP'] = 'Yes, please'

    # XXX: get these using getopt
    kernel_tree = '' # os.path.join(os.environ['HOME'], 'gsrc', 'linux-2.6')
    arch = 'arm'
    target = sys.argv[1]
    defconfig_src = os.path.join(kernel_tree, 'arch/%s/configs/%s' % (arch, target))

    subprocess.check_call(['make', '-s', 'ARCH=%s' % arch, target])
    origconfig = list(open('.config'))
    config = list(origconfig)
    config_size = os.stat('.config').st_size

    i = 0

    while i < len(config):
        print 'test for %r' % config[i]
        defconfig = open(defconfig_src, 'w')
        defconfig.writelines(config[:i])
        defconfig.writelines(config[i + 1:])
        defconfig.close()
        subprocess.check_call(['make', '-s', 'ARCH=%s' % arch, target])

    defconfig = open(defconfig_src, 'w')

The IT8720F has no VIN7 pin, so VCCH should always be routed
internally to VIN7 with an internal divider. Curiously, there still
is a configuration bit to control this, which means it can be set
incorrectly. And even more curiously, many boards out there are
improperly configured, even though the IT8720F datasheet claims that
the internal routing of VCCH to VIN7 is the default setting. So we
force the internal routing in this case.

It turns out that all boards with the wrong setting are from Gigabyte,
so I suspect a BIOS bug. But it's easy enough to workaround in the
driver, so let's do it.

Many codecs now clear the pin controls at suspend via snd_hda_shutup_pins()
for reducing the click noise at power-off.  But this leaves some pins
uninitialized, and they'll be never recovered after resume.

This patch adds the proper recovery of cleared pin controls on resume.
Also it adds a check of bus->shutdown so that pins won't be cleared at
module unloading.
