exec.c has a comment 'XXX: optimize' for lduw_phys/stw_phys,
so let's do it, along the lines of stl_phys.

The reason to address 16 bit accesses specifically is that virtio relies
on these accesses to be done atomically, using memset as we do now
breaks this assumption, which is reported to cause qemu with kvm
to read wrong index values under stress.

updated version of an old patch
http://xenon.stanford.edu/~eswierk/misc/qemu-linuxbios/qemu-piix-ram-size.patch
that together with
http://www.mail-archive.com/linuxbios@linuxbios.org/msg02390.html
(which is already in coreboot trunk) allows coreboot to autodetect the amount of RAM within qemu/kvm from a register in i440 northbridge.

The message on the old patch states:
Unfortunately the current version of qemu does not set these
registers, but I have patched qemu so that it emulates the i440 more
faithfully in this regard.

With three different make binaries I have available, configuring a

Makefile:27: *** missing separator.  Stop.

don't understand why this hasn't been a problem for other folks before.

Currently the commandline to create a virtual-filesystem pass-through between

#qemu -fsdev fstype,id=ID,path=path/to/share \
      -device virtio-9p-pci,fsdev=ID,mount_tag=tag \

This patch provides a syntactic short-cut to achieve the same as follows:
#qemu -virtfs fstype,path=path/to/share,mount_tag=tag

This will be internally expanded as:
#qemu -fsdev fstype,id=tag,path=path/to/share, \
