Hi,
This is the linux-xen portion of kexec for ia64 xen v20080125.
Please see the slightly lengthier cover to the xen series of

Hi Alex,
Although it isn't clear from the patch, the code is gaurded by CONFIG_KEXEC.
As you suggest, xen_machine_kexec_register_resources() needed to
be protected, I have used is_initial_xendomain() as this port
of kexec isn't supposed to do anything on non-privelaged domains (yet).

init_bootmem(), which is called in
find_memory(). However xen_machine_kexec_setup_resources() is indirectly
called earlier on in find_memory().
Another one for xen-devel? Thanks,

it was included in 2.6.22, possibly before. I can
just drop this change from my patchset if you like. However, I think
that it makes sense to keep it in given that a backport of ia64 kexec is
included in this series, and this change is really just part of that.
