As requested by the KVM maintainers, remove the addprefix used to
refer to the main KVM code from the arch code, and replace it with
a KVM variable that does the same thing.

We hope to at some point deprecate KVM legacy device assignment in
favor of VFIO-based assignment. Towards that end, allow legacy
device assignment to be deconfigured.

We changed a few things in non-ia64 code paths. This patch blindly applies
the changes to the ia64 code as well, hoping it proves useful in case anyone
revives the ia64 kvm code.

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.

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.

This patch enables coalesced MMIO for ia64 architecture.
It defines KVM_MMIO_PAGE_OFFSET and KVM_CAP_COALESCED_MMIO.
It enables the compilation of coalesced_mmio.c.

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]
