[Xen-devel] x86_64 compile error / isa_bus_to_virt_needs_PRIVILEGED_BUILD

["Vipin Bhargava" <vipin@xxxxxxxxxxxxxxx>]

Using FC3 x86_64 and doing "make ARCH=xen world", I get the
following:

  CC      arch/xen/x86_64/kernel/mpparse.o
arch/xen/x86_64/kernel/mpparse.c: In function `get_smp_config':
arch/xen/x86_64/kernel/mpparse.c:549: error:

function)

make: *** [kernels] Error 1

On a complete guess -
The .config shows:
 # CONFIG_XEN_PHYSDEV_ACCESS is not set

Why does include/asm-xen/asm-x86_64/io.h not seem to do this
properly with:

#ifdef CONFIG_XEN_PHYSDEV_ACCESS
#define isa_bus_to_virt(_x) (void *)(__fix_to_virt(FIX_ISAMAP_BEGIN) + (_x))
#else
#define isa_bus_to_virt(_x) isa_bus_to_virt_needs_PRIVILEGED_BUILD
#endif

xen0 compiles fine.
