Hi Jan.
Those deviations can be narrowed (specifying file name):
-config=MC3A2.R5.5,reports+={deliberate,
"any_area(any_loc(file(^xen/include/xen/bitops\\.h$)) &&
macro(name(__test_and_set_bit||__test_and_clear_bit||__test_and_change_bit||test_bit)))"}
-config=MC3A2.R5.5,reports+={deliberate,
"any_area(any_loc(file(^xen/common/grant_table\\.c$))&¯o(name(update_gnttab_par||parse_gnttab_limit)))"}
-config=MC3A2.R5.5,reports+={deliberate,
"any_area(any_loc(file(^xen/include/xen/irq\\.h$))&¯o(name(pirq_cleanup_check)))"}
Are you OK with it?
Dmytro.
