[Qemu-devel] [kqemu] gpf in memory access

I was playing with gpm (mouse daemon) in Linux guest and apparently my
gpm binary is broken and with the "ps2" plugin it segfaults because of
a general protection fault when trying to load a quadword from the
address 0xff00000000000000. Under qemu as well as on the my physical
amd64 it just segfaults, but under kqemu if makes kqemu panic and qemu
aborts. Attached is a patch to make kqemu pass the gpf to qemu. It's
probably wrong but it gives identical behaviour as with -no-kqemu or
as on physical cpu, in this case.
