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.
