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.

The usermode PAGE_RESERVED code is not required by the current mmap
implementation, and is already broken when guest_base != 0.
Unfortunately the bsd emulation still uses the old mmap implementation,
so we can't rip it out altogether.

When -d cpu logging was handled by target-foo/translate.c,
it was controled by DEBUG_DISAS, which is enabled by default.
Use the same condition in cpu_exec.
At the same time, reduce the if-deffery by assuming no flags
update is required for the target.

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
pristine QEMU tree and attempting to make gives the cryptic:
Makefile:27: *** missing separator. Stop.
This patch fixes it (presumably because it makes the output of
`set-vpath' be an empty string, rather than a bit of whitespace), but I
don't understand why this hasn't been a problem for other folks before.

It's emitted when the Virtual Machine resumes execution.
We currently have the STOP event but don't have the matching
RESUME one, this means that clients are notified when the VM
is stopped but don't get anything when it resumes.

Currently the commandline to create a virtual-filesystem pass-through between
the guest and the host is as follows:
#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, \
-device virtio-9p-pci,fsdev=tag,mount_tag=tag \
