[PATCH] xen,tools: pincpu use vcpu and cpumap_t
The following patch updates the dom0 pincpu operation to read the VCPU
value from the xend interface rather than hard-coding the exec_domain to
0. This prevented pinning VCPUS other than 0 to a particular cpu. The
pincpu cpu argument is replaced with cpumap, a u64 bitmap representing
which CPUs a VCPU can use.
I added the number of VCPUS to the main xm list output and also included
a new sub-option to xm list to display the VCPU to CPU mapping. While
working on the pincpu code, I fixed an out-of-bounds indexing for the
pincpu operation that wasn't previously exposed since the
vcpu/exec_domain value was hard-coded to 0.

Remove twisted from the HTTP server and replace with a
threaded server. Add classes to provide tcp and unix servers
using threads instead of twisted. Remove use of twisted from
the consoles, event server and HTTP resources

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.

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.

Support for USB virtualisation. Adds the USB frontend / backend, update build options,
make the control tools understand USB interfaces.
One extra file from vanilla Linux is imported (linux-2.4.28-xen-sparse/drivers/usb/hcd.c)
because small changes were required to make XenU domains build with a USB frontend. This
will not be required for the revised host controller infrastructure in Linux 2.6.
To use this, set "usb = " a list of USB ports in the domain config file. Ports are
specified as a path, e.g. '1' = the first USB port on the host, '1/2' is the second port
on the hub on the first host port, etc.
Should work for most mass storage and isochronous devices. May work for some HID devices
but these are not as intelligent and may have trouble supporting virtualisation.
Add an optional parameter (vcpus) to the xc_linux_build function replacing
the getenv() previously used and removing the requirement of using maxcpus
kernel parameter to limit the number of virtual cpus a guest uses. The value
can now be controlled in the domain configuration files.
The default value of 1 is set in XenDomainInfo.py but is overridden by
parsing the config value.
