amd_iommu_init: remove __init from amd_iommu_erratum_746_workaround

commit 318fe78 ("IOMMU, AMD Family15h Model10-1Fh erratum 746 Workaround")
added amd_iommu_erratum_746_workaround and it's marked as __init, which is wrong

WARNING: drivers/iommu/built-in.o(.text+0x639c): Section mismatch in reference from the function iommu_init_pci() to the function .init.text:amd_iommu_erratum_746_workaround()
The function iommu_init_pci() references
the function __init amd_iommu_erratum_746_workaround().
This is often because iommu_init_pci lacks a __init
annotation or the annotation of amd_iommu_erratum_746_workaround is wrong.

iommu: OMAP: build only on OMAP2+

The OMAP IOMMU driver intentionally fails to build on OMAP1
platforms, so we should not allow enabling it there.

iommu/amd: Make sure dma_ops are set for hotplug devices

There is a bug introduced with commit 27c2127 that causes
devices which are hot unplugged and then hot-replugged to
not have per-device dma_ops set. This causes these devices
to not function correctly. Fixed with this patch.

vfs/splice: Fix missed checks in new __kernel_write() helper

Commit 06ae43f34bcc ("Don't bother with redoing rw_verify_area() from
default_file_splice_from()") lost the checks to test existence of the
write/aio_write methods.  My apologies ;-/

Eventually, we want that in fs/splice.c side of things (no point
repeating it for every buffer, after all), but for now this is the
obvious minimal fix.

Merge tag 'iommu-fixes-v3.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU fixes from Joerg Roedel:
 "Here are some fixes which have collected since Linux v3.9-rc1.

  The most important one fixes a long-standing regressen which make
  re-hotplugged devices unusable when AMD IOMMU is used.

  The other patches fix build issues (build regression on OMAP and a
  section mismatch).  One patch just removes a duplicate header include."
