KVM: x86: use vcpu-specific functions to read/write/translate GFNs
We need to hide SMRAM from guests not running in SMM. Therefore, all uses of kvm_read_guest* and kvm_write_guest* must be changed to check whether the VCPU is in system management mode and use a different set of memslots. Switch from kvm_* to the newly-introduced kvm_vcpu_*, which call into kvm_arch_vcpu_memslots_id. Reviewed-by: Radim Krčmář <rkrcmar@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
