x86, suspend: Correct the restore of CR4, EFER; skip computing EFLAGS.ID

The patch:

    73201dbe x86, suspend: On wakeup always initialize cr4 and EFER

... was incorrectly committed in an intermediate (unfinished) form.

- We need to test CF, not ZF, for a bit test with btl.
- We don't actually need to compute the existence of EFLAGS.ID,
  since we set a flag at suspend time if CR4 should be restored.

x86/reboot: Remove quirk entry for SBC FITPC

Remove the quirk for the SBC FITPC. It seems ot have been
required when the default was kbd reboot, but no longer required
now that the default is acpi reboot. Furthermore, BIOS reboot no
longer works for this board as of 2.6.39 or any of the 3.x
kernels.

Drivers must not include omap_hwmod.h at, it will be

drivers will also start including omap_hwmod.h.

Note that also plat/cpu.h will be going away, so the
omap_rev check needs to be replaced with mcpdm-watchdog

ASoC: ams-delta: Convert to use snd_soc_register_card()

The old method of registering with the ASoC core by creating a
"soc-audio" platform device no longer works for Amstrad Delta sound card
after recent changes to drvdata handling (commit
0998d0631001288a5974afc0b2a5f568bcdecb4d, 'device-core: Ensure drvdata =
NULL when no driver is bound'.

Use snd_soc_register_card() method instead, as suggested by the ASoC
core generated warning message, and move both the card and codec
platform device registration to the arch board file where those belong.

Created and tested against linux-3.6-rc5.

Commit 9c650ffc ("TTY: ircomm_tty, add tty install") split _open() to

out of open(), but never added it to install() - causing a NULL ptr

To fix this we need to look at condition before calling __ratelimit in

FATAL: drivers/tty/serial/sccnxp: struct platform_device_id is not

So fix this problem up before someone oopses their box when loading the
driver, as this breaks the build.

The crash happens here in i915_gem_entervt_ioctl() :

    3659          BUG_ON(!list_empty(&dev_priv->mm.active_list));
    3660          BUG_ON(!list_empty(&dev_priv->mm.flushing_list));
 -> 3661          BUG_ON(!list_empty(&dev_priv->mm.inactive_list));
    3662          mutex_unlock(&dev->struct_mutex);

Quoting Chris :
  "That BUG_ON there is silly and can simply be removed. The check is to
   verify that no batches were submitted to the kernel whilst the UMS/GEM
   client was suspended - to which the BUG_ONs are a crude approximation.
   Furthermore, the checks are too late, since it means we attempted to
   program the hardware whilst it was in an invalid state, the BUG_ONs are
   the least of your concerns at that point."

drm/i915: paper over a pipe-enable vs pageflip race

I've discovered this on my ivb machine while stress-testing the new
flip_tests. Only harmful effect observed is that the timestamp is a
bit bogus.

Note that this is empirical duct-tape: I've noticed that we seem to
only ever miss the very first vblank irq right after enabling the
pipe. And with this hack applied I couldn't reproduce the failure case
anywhere else any more.

USB: Enable LPM after a failed probe.

Before a driver is probed, we want to disable USB 3.0 Link Power
Management (LPM), in case the driver needs hub-initiated LPM disabled.
After the probe finishes, we want to attempt to re-enable LPM, order to
balance the LPM ref count.

When a probe fails (such as when libusual doesn't want to bind to a USB
3.0 mass storage device), make sure to balance the LPM ref counts by
re-enabling LPM.

This patch should be backported to kernels as old as 3.5, that contain
the commit 8306095fd2c1100e8244c09bf560f97aca5a311d "USB: Disable USB
3.0 LPM in critical sections."
