Joerg Roedel c4fa386428 KVM: rename vtd.c to iommu.c
Impact: file renamed

The code in the vtd.c file can be reused for other IOMMUs as well. So
rename it to make it clear that it handle more than VT-d.

Xiantao Zhang 7d63797815 KVM: ia64: Define printk function for kvm-intel module
kvm-intel module is relocated to an isolated address space
with kernel, so it can't call host kernel's printk for debug
purpose. In the module, we implement the printk to output debug
info of vmm.

Xiantao Zhang 25c437b01f KVM: ia64: fix GVMM module including position-dependent objects
The GVMM module is position independent since it is relocated to the guest
address space.

Commit ea696f9cf ("ia64 kvm fixes for O=... builds") broke this by linking
GVMM with non-PIC objects.

Fix by creating two files: memset.S and memcpy.S which just include the files
under arch/ia64/lib/{memset.S, memcpy.S} respectively.

[akpm: don't delete files which we need]
