I suspect that it would needs some code in this function in order to
support soft reset on ARM. If so, should not you return -ENOSYS until
someone take care of the ARM support?
I was hoping kexec for ARM will magically work without any arch-specific
bits here :-)
I don't know how work kexec for Xen, but I think we will have at least
to do the same as x86 for the shared info page.
Sure, let's make it -ENOSYS.
Thank you!
