The variable "sun" defined in acpiphp_glue.c as "unsigned long". But the struct acpiphp_slot defines the sun as u32 in acpiphp.h.
On the ia64, since the "unsigned long" is u64, the above mismatch may cause the problem if the _SUN returns the value in 64 bits.
The following patch change the definition in acpiphp.h to match the type of sun with other places.
