2.6.27-stable review patch. If anyone has any objections, please let us
know.

From: Andreas Herrmann <andreas.herrmann3@amd.com>
commit f609891f428e1c20e270e7c350daf8c93cc459d7 upstream
We are on 64-bit so better use u64 instead of u32 to deal with
addresses:
static void __init iommu_set_device_table(struct amd_iommu *iommu)
{
u64 entry;
...
entry = virt_to_phys(amd_iommu_dev_table);
...
(I am wondering why gcc 4.2.x did not warn about the assignment
between u32 and unsigned long.)
