KVM: ia64: Fix kvm_arch_vcpu_ioctl_[gs]et_regs()

Browse source

Fix kvm_arch_vcpu_ioctl_[gs]et_regs() to do something meaningful on
ia64. Old versions could never have worked since they required
pointers to be set in the ioctl payload which were never being set by
the ioctl handler for get_regs.

In addition reserve extra space for future extensions.

The change of layout of struct kvm_regs doesn't require adding a new
CAP since get/set regs never worked on ia64 until now.

This version doesn't support copying the KVM kernel stack in/out of
the kernel. This should be implemented in a seperate ioctl call if
ever needed.
