Subject: [PATCH] pit-in-hv.patch
- Use ac_timer for PIT interrupt injection (more accurate time keeping)
- Accelerate some critical PIT I/O operations in the hypervisor
(saves 15us per op). Cuts down guest timer interrupt handler execution time
by a third.
- If the domain is scheduled out, make sure that interrupts are not lost
- Add a generic framework for device I/O interception

Fix the synchronization issues between xend and the device model at
startup time.
Initialize the shared page in the hypervisor. Otherwise, the hypervisor
might try to inject spurious interrupts into the guest due to
uninitialized data.

This very simple patch is really just cosmetic. It "fixes" xend so that
it doesn't report restart as: "WARNING (XendDomainInfo:1038) Unknown
config field restart" in the xend.log. I'm not sure who should sign off
on this, but the patch is attached.

As pointed out on the xen-devel list, the vm86 call was not very robust in
Xen.
It turned out to be due to a missing check in the pagefault handler,
determining whether the pagefault came from userspace or from the kernel.
Now the syscall-crash tool doesn't cause any "Oops" on the vm86 calls anymore.

unnecessary includes (yet).
2. Add explicit align arg, although current implementation
over-aligns.
3. Add list_for_each_entry_safe().
4. Make xmalloc_array use _xmalloc_array, to avoid duplicate eval
of "num" arg.

slab.c in Linux is not a very nice piece of code: the version in Xen has
been hacked a certain amount and is not a vision of beauty either.
Given how rare and non-time-critical dynamic allocations are in Xen,
this replaces the 1800-line slab.c with a 160-line malloc.c which is
written as simply as possible for future enhancement.

Right now, the memory for the 1:1 physical mode page tables comes from the
VMX domain's memory. With this change, when the user asks for a domain with
M Megabytes of memory, we actually allocate M+N megabytes in xend, where
N is the memory for the page table pages.
This simplifies the code in the device models that maps guest memory (we
now map all of it) and the E820 map can also give the full M megabytes to
the guest.

Currently xcs is run by xend in xen-unstable by simply making it a child
process. If you launch xend from an ssh session, the session won't exit
because the xcs still is connected to it's controlling terminal.
xcs should daemonize itself to prevent this from happening. This patch
does that along with making the domain id => port mapping dynamically
allocated.

With ipv6, every network interface always has a link local
address. This fools the network script into thinking that
xen-br0 already has a network address, and it refuses to
transfer over eth0's IP address to xen-br0.
By grepping for 'inet ' instead of just 'inet', the network
script is no longer fooled and does the right thing. This
patch makes Xen networking work again on my Fedora system.
