The Xen community wants to avoid using variadic functions except for specific circumstances where it feels appropriate by strict code review. Functions hypercall_create_continuation and hypercall_xlat_continuation are internal helpers made to break long running hypercalls into multiple calls. They take a variable number of arguments depending on the original hypercall they are trying to continue. Add SAF deviations for the aforementioned functions. Add deviation for printf()-like functions. --- Changes in v3: - use regexes to exempt all .*printk and .*printf functions, instead of manually listing them one by one; - rebase: change SAF-3-safe in SAF-4-safe. Changes in v2: - replace "related to console output" with "printf()-like functions"; - replace "special hypercalls" with "internal helpers".
