With a correct dev->dma_mask before calling dmabounce_register_dev(),
dma_needs_bounce() is not necessary.

The sa1111, though, is a bit complicated. Until it's fully understood
and fixed, dma_needs_bounce() for sa1111 is kept if CONFIG_SA1111 is
enabled with no side effect (with the condition of machine_is_*)

Thanks for Mike Rapoport to fix one error in the original version of
the patch and get this tested.

Not tested and enabled on MMP at this moment, and since the IRQ

back into mach-pxa/. Will introduce the PMU device to MMP once

Since commit a48c24a6, the
camera is not working anymore.

After the v4l2 migration, the mt9m111 camera board
information was not passed to the i2c layer anymore, but
stored for future use of v4l2 (through soc_camera).

Because mioa701_i2c_devices[] was tagged as "__initdata",
and because after the v4l2 migration, the new structure
"iclink" references it, the mt9m111 driver is not probed
anymore, as part of "iclink" is not valid (discarded after
kernel init).

Although there is not compilation error, nor runtime oops,
this patch restores a working camera on the mioa701 board.

  PCI: hotplug/cpqphp, fix NULL dereference
  Revert "PCI: create function symlinks in /sys/bus/pci/slots/N/"
  PCI: change resource collision messages from KERN_ERR to KERN_INFO

Yannick found that video does not work with 2.6.34.  The cause of this
bug was that the BIOS had assigned the wrong range to the PCI bridge
above the video device.  Before 2.6.34 the kernel would have shrunk
the size of the bridge window, but since
  d65245c3 PCI: don't shrink bridge resources
the kernel will avoid shrinking BIOS ranges.

So zero out the old range if we fail to claim it at boot time; this will
cause us to allocate a new range at startup, restoring the 2.6.34
behavior.

Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009.

There are devices out there which are PCI Hot-plug controllers with
compaq PCI IDs, but are not bridges, hence have pdev->subordinate
NULL. But cpqphp expects the pointer to be non-NULL.

Add a check to the probe function to avoid oopses like:
BUG: unable to handle kernel NULL pointer dereference at 00000050
IP: [<f82e3c41>] cpqhpc_probe+0x951/0x1120 [cpqphp]
*pdpt = 0000000033779001 *pde = 0000000000000000

The "file" argument for fsync is never null so we can remove this check.

If btrfs_ioctl_snap_destroy() deletes a snapshot but finishes
with end_transaction(), the cleaner kthread may come in and
drop the root in the same transaction.  If that's the case, the
root's refs still == 1 in the tree when btrfs_del_root() deletes
the item, because commit_fs_roots() hasn't updated it yet (that
happens during the commit).

This wasn't a problem before only because
btrfs_ioctl_snap_destroy() would commit the transaction before dropping
the dentry reference, so the dead root wouldn't get queued up until
after the fs root item was updated in the btree.

Since it is not an error to drop the root reference and the root in the
same transaction, just drop the BUG_ON() in btrfs_del_root().
