- only caller is start_kernel
- change to static __init
- also move running_on_sim to xensetup.c, and change it from unsigned
long to int, since it's just a boolean
- declare running_on_sim in config.h near some other externs
Tested by building, booting, starting a PV guest on rx2620.

Nvram saving is always executed even if a domain is destroyed by a
configuration parameter error. In this case, Nvram saving function
will get a bad address for the NVRAM data and save garbage into the
NVRAM file. Configuring a wrong vif parameter can expose this issue.
This patch fixes the issue by adding an address check function in
NVRAM saving path.

Since setting up bridging involves bringing down the network interface,
bridging clearly isn't compatible with the likes of NFS or iSCSI root.

When failing a migration / save due to the domain owning a PCI device
make sure that we tell the user what went wrong!

This can potentially cause a whole machine crash, which I think has
been seen in the wild. The case in the wild was caused by xendomains
auto-resuming domains on reboot, so it wasn't even operator error.
There's no sane way to migrate or suspend domains with PCI devs,
so I disallow it completely.

This patch adds a duplication definition check for devices.
It checks the following definitions.
- vbd : uname and device name
- vif : mac

By the time we test if addr is the upper word it has already been
aligned to the 8 byte pte size.

Check the 'log_reload' on every iteration of the select() loop, not just when
select() returns EINTR. This is because the log reload signal may have
iterrupted a syscall other than select & thus without this change we
might miss the reload signal. The second change makes us process the
hypervisor logs on every iteration of the loop, not just upon timeouts.
This is because if a guest VM were consistently sending some log message
and < 1 second period, the select() would never hit the 1 second timeout
and thus never process the HV logs.
Thanks to Markus Armbruster for pointing out both these edge cases

Following functions can be __init in Linux, however shouldn't
in Xen. __print_IO_APIC is called by keyhandler, while
setup_ioapic_dest is invoked in one platform hypercall.
