[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 3/5] xen: arm: include public/xen.h in foreign interface checking
mkheader.py doesn't cope with
struct foo { };
so add a newline.
Define unsigned long and long to a non-existent type on ARM so as to catch
their use.
Teach mkheader.py to cope with structs which are ifdef'd.
