Older KVM versions save CS dpl value to an invalid value for real mode guests
(0x3). This patch detect this situation when loading CPU state and set all the
segments dpl to zero.
This will allow migration from older KVM on host without unrestricted guest
to hosts with restricted guest support.
For
Older KVM version put invalid value in the segments registers dpl field for
real mode guests (0x3).
This breaks migration from those hosts to hosts with unrestricted guest support.
We detect it by checking CS dpl value for real mode guest and fix the dpl values
of all the segment registers.

At the moment the guest kernel issues two types of task management
requests to the hypervisor - task about and lun reset. This adds
handling for these tasks. As spapr-vscsi starts calling scsi_req_cancel(),
free_request callback was implemented.

After the commit 182735e cpu: Make first_cpu and next_cpu CPUState
we can no longer blindly use cpu->next_cpu->env_ptr to get CPUArchState

The KVM stub variables and functions don't depend on target specific data
types, so it is possible to compile kvm-stub.c only once.
Integrating the target specific KVM stubs for ARM, I386 and PPC in the
