K 10 svn:author V 3 dim K 8 svn:date V 27 2018-01-08T18:42:40.431268Z K 7 svn:log V 348 Add explanatory comment for r327622: clang 6.0.0 and higher warn about the ACPI_ROOT_OBJECT and ACPI_TO_POINTER macros from acpica's actypes.h header, that they use arithmetic on a null pointer treated as a cast from integer to pointer, which is a GNU extension. We turn off the warning, because this is in contributed code. Requested by: rakuco END
