typedef struct dom0_setvcpucontext {
 /* IN variables. */
 domid_t domain;
 uint32_t vcpu;
 /* IN/OUT parameters */
 vcpu_guest_context_t ctxt;
} dom0_setvcpucontext_t;
Note that 'ctxt' is no longer a pointer.
This is a far simpler solution, though it does introduce a size
limitation for memory-based hcalls; I went into some detail in my other
mail. Could you reply to that if there's something unclear?
