1. Move definitions of struct i386_*_args to the header file sysarch.h, since they are part of the sysarch API. struct i386_get_ldt_args and i386_set_ldt_args were identical, therefore make them into one struct i386_ldt_args. Libc should use these definitions as well. 2. Return a more sensible EOPNOTSUPP for unknown operations. Reviewed by: marcel
