Bug 10446

I'm building xorg-server-1.2.99.903.  The compilation ends with:

make[5]: *** [lnx_agp.lo] Error 1

The error indicates that the typedef for __u16 has not been included.  That typedef lives in <asm/types.h>, which is #included by <linux/types.h>.  Using gcc -E, I can see that <linux/types.h> is included in lnx_agp.c, only once, via <linux/kd.h>, but none of its contents are used, as if the _LINUX_TYPES_H guard macro were already defined.  I haven't been able to find any place that defines it, though.  As a workaround, I added "#include <linux/types.h>" to the top of lnx_agp.c, and that eliminated this error.
