Consolidate the code for making and getting ucalls.  All architectures pass
the ucall struct via memory, so filling and copying the struct is 100%
generic.  The only per-arch code is sending and receiving the address of
said struct.

Tested on x86 and arm, compile tested on s390 and RISC-V.

Sean Christopherson (3):
  KVM: selftests: Consolidate common code for popuplating ucall struct
  KVM: selftests: Consolidate boilerplate code in get_ucall()
  KVM: selftest: Add __weak stubs for ucall_arch_(un)init()
