Delta patches for v4 of the guest printf series to enable guest_printf_test
for all architectures.  Sending all 36 patches seemed counter-productive,
and I want to get input on adding ucall.h asap.

v4.1:
 - Add ucall.h and have each arch UCALL_EXIT_REASON so that generic code
   can query whether or not a ucall exit actually occurred. [Drew]
 - Use UCALL_EXIT_REASON in guest_printf_test.c and enable the test for
   all architectures. [Drew]

v4: https://lore.kernel.org/all/20230729003643.1053367-1-seanjc@google.com (local)

Aaron Lewis (1):
  KVM: selftests: Add a selftest for guest prints and formatted asserts

Sean Christopherson (2):
  KVM: selftests: Add arch ucall.h and inline simple arch hooks
  KVM: selftests: Add #define of expected KVM exit reason for ucall
