Update functions to return -1 on error, 0 on success. Simplify init_page() and make sure errno is assigned. Adjust PERROR/ERROR usage, use PERROR early because it overwrites errno. Adjust xenpaging_populate_page() to handle gfn as unsigned long. Update xenpaging exit code handling. xenpaging_teardown cant possible fail. Adjust mainloop to indicate possible errors to final exit.
