Merge branch 'stable/late-swiotlb.v3.3' into stable/for-linus-3.7
* stable/late-swiotlb.v3.3: xen/swiotlb: Fix compile warnings when using plain integer instead of NULL pointer. xen/swiotlb: Remove functions not needed anymore. xen/pcifront: Use Xen-SWIOTLB when initting if required. xen/swiotlb: For early initialization, return zero on success. xen/swiotlb: Use the swiotlb_late_init_with_tbl to init Xen-SWIOTLB late when PV PCI is used. xen/swiotlb: Move the error strings to its own function. xen/swiotlb: Move the nr_tbl determination in its own function. swiotlb: add the late swiotlb initialization function with iotlb memory xen/swiotlb: With more than 4GB on 64-bit, disable the native SWIOTLB. xen/swiotlb: Simplify the logic.
