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.

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 \
