Alexander Graf 8e5b26b55a KVM: PPC: Use accessor functions for GPR access
All code in PPC KVM currently accesses gprs in the vcpu struct directly.

While there's nothing wrong with that wrt the current way gprs are stored
and loaded, it doesn't suffice for the PACA acceleration that will follow
in this patchset.

So let's just create little wrapper inline functions that we call whenever
a GPR needs to be read from or written to. The compiled code shouldn't really
change at all for now.

Alexander Graf e15a113700 powerpc/kvm: Sync guest visible MMU state
Currently userspace has no chance to find out which virtual address space we're
in and resolve addresses. While that is a big problem for migration, it's also
unpleasent when debugging, as gdb and the monitor don't work on virtual
addresses.

This patch exports enough of the MMU segment state to userspace to make
debugging work and thus also includes the groundwork for migration.

Alexander Graf c215c6e49f Add book3s_64 specific opcode emulation
There are generic parts of PowerPC that can be shared across all
implementations and specific parts that only apply to BookE or desktop PPCs.

This patch adds emulation for desktop specific opcodes that don't apply
to BookE CPUs.
