The following series implements KVM support for ARM processors,
specifically on the Cortex A-15 platform.
The patch series applies to the arm-lpae branch of ARM Ltd's kernel
tree. This is Version 4 of the patch series, but the first two versions
were reviewed outside of the KVM mailing list. Changes can also be
pulled from:
git://git.ncl.cs.columbia.edu/pub/git/linux-kvm-arm kvm-a15-v4
The implementation is broken up into a logical set of patches, the first
one containing a skeleton of files, makefile changes, the basic user
space interface and KVM architecture specific stubs. Subsequent patches
implement parts of the system as listed:
1. Skeleton
2. Identity Mapping for Hyp mode
3. Hypervisor intitalization
4. Hyp mode memory mappings and 2nd stage preparation
5. World-switch implementation and Hyp exception vectors
6. Emulation framework and CP15 emulation
7. Handle guest user memory aborts
8. Handle guest MMIO aborts
9. Handle userspace IRQ/FIQ injection
10. Support guest wait-for-interrupt instructions.
Testing:
Limited testing, but have run GCC inside guest, which compiled a small
hellow-world program, which was successfully run. Hardware still
unavailable, so all testing has been done on ARM Fast Models.
For a guide on how to set up a testing environment and try out these
patches, see:

Pretty nice, and once again I congratulate you for not having to
virtualize x86.
I don't know how close you feel you are to merging, but from my point of
view things are looking good. We'll need to coordinate trees and acks
since this is touching more than just arch/arm/kvm.

Suggest eliminating the arm_ prefixes.
