RE: [Xen-ia64-devel] [PATCH] Add vga font init for qemu/ia64

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

Hi Ke --

This is a fix for ia64 but the file is generic so the patch
should be submitted to xen-devel.

It would probably be better to use a more general ifdef
(for example, #ifdef ARCH_NEED_VGA_FONT_INIT) in case
other arch's need this in the future.  Perhaps a
test for ia64 can be put in tools/ioemu/configure to
properly define this.

Thanks,
Dan
