With this patch you can set QEMU_TAG to check out a specific version.
When we set it, QEMU_TAG ought to be in Config.mk, I think.

The creation operation also opens a file, we need to allocate a

* Uninitialized dev_bus_addr argument to GNTTABOP_unmap_grant_ref
results in an angry hypervisor.
* Set errno in libxc and return -1 on error.
* op.status is a int16_t, so it should be printed with PRId16.
* Don't print domids[0] or refs[0] if the ptr is NULL. It's more
polite to crash later, after the message has been printed.

Allow dom0 to provide information incrementally.

I've implemented a grant map for mini-os to support the xc_gnttab_*()
functions, the equivalent of gntdev in linux. This is useful for my
work in putting xenstored in a stub domain.

The current implementation in minios of xc_evtchn_pending doesn't set
read=0 when there is exactly one port pending. This resulted in
select() incorrectly reporting the file descriptor as ready.

The current stdvga code never checks if the copy_from/to_guest calls
fail, and thus silenty fails if both sides of an IOREQ_COPY points
into mmio space. This patch fixes this and makes the code correctly
handle intra-vga-mem copies, as well as log & turn off caching if some
more "exotic" type of mmio (say, copy from vga mem to some other
device's iomem), so that such mmio reqs will fall through to regular
ioemu where they can hopefully be handled correctly.
In practice, this patch fixes a number of graphical glitches for
guests running in standard vga mode, including a corrupted OS/2 boot
graphic.

Dom0 C/S 593 hooks the pci bus probe and remove function. When
probing a function at booting time, it will first add the device into
Dom0's list through a hypercall, then execute the driver's probe
function. If the probe function fails, another hypercall is called to
remove the device from Dom0's list. But for some RMRR devices, for
example, USB devices, they may still be in use for some operation by
BIOS at booting time. So when removing those kind of devices, we
should still keep the RMRR information.
Also add a small fix for "for_each_rmrr_device".

Addresses a number of argument handling bugs in the flask_op hypercall
in the XSM:Flask module. Thanks to Rafal Wojtczuk at McAfee for
reporting the issues and Tim Deegan at Citrix for providing an
initial patch.
This patch addresses the following issues:
- bounds checking and validation on input arguments to flask_op
- updated ABI/API, size and cmd are now uint32_t
- updated userspace tools and libraries to account for ABI/API
changes
- implemented all copies using from/to guest, better portability
- implemented upper bounds checking on op->cmd, op->size
- implemented sanity checking on op->size and op->buf
- implemented bit vector for checking from/to usage on op->cmd
