Fix floppy driver on Xen -- vmalloc/vfree are unsafe because of the
context that the fd_dma functions may get called from.

Check-in of the sparse tree for FreeBSD 5.3 (version 050317)
This currently supports running as a domU.
- to create freebsd-5.3-xenU run fbsdxensetup from anywhere in the tree
- once created go to freebsd-5.3-xenU on a FreeBSD 5.3 machine, run
xenfbsd_kernel_build - you'll find kernel and kernel.debug under
i386-xen/compile/XENCONF
See http://www.fsmware.com/xenofreebsd/5.3/xenbsdsetup.txt
Thanks to NetApp for their contributions in support of the FreeBSD port to Xen
.

This patch will cause xcsdump to display more verbose information about the
xcs traffic.
This includes human-readable names of the message type and subtype and
all of the parameters and their values. It's against today's
xen-unstable and has been tested against a number of xen-unstable
snapshots going back a few weeks (one line has to be removed to support
older versions of xen-unstable).
The message types displayed are configurable via a bitmask passed as a
'-v' option in xcsdump.
The code is very useful for figuring out what management tools (Xend,
VM-Tools) are actually doing. I would not have been able to write
vm-tools without it.

I added support to Anthony's vm-tools so that it can start VMX enabled
partitions directly (including forking off a copy of the device-model
with the user's environment variables, such as $DISPLAY). For this I found
it useful to harden xc_vmx_build.c so that it doesn't dump core when called
incorrectly.

Allow domain0 to see PCI bridges. It should be able to deal with
seeing PCI buses twice (once as a 'root bridge' from Xen; once by
scanning behind a PCI-PCI bridge itself), and this gets rid of
problems where the bridge needs to be seen by XenLinux for drivers
to work (e.g., Mellanox Infiniband chipsets).

Linux 2.6 now always uses writable page tables (even SMP builds). Also
use native definitions for atomic read-modify-write operations on
ptes. Fixed instruction emulator in Xen.

If a Linux guest is allocated more memory than it can use (due to
highmem constraints) it will now give that RAM back to Xen.

Define new io_remap_pfn_range() for mapping device space into user
applications. Patch drivers to use this instead of remap_pfn_range()
where appropriate. This patch should be pushed upstream to the kernel
maintainers.

Tidy the x86 emulator interface, and use it from within the
writable pagetable algorithm to deal with otherwise unhandleable cases.
For example: L1 mapped at multiple L2 slots; L1 that maps itself; L1
that also maps the code making the update, or the kernel stack.
This provides a proof-of-concept for the emulator that can be picked
up for the VMX code to improve the device-model emulation.
