> does this affect ia64 in any way?

I remember Eric complaining that set_virtual_address_map() was a one
way trap door with no way to get back to physical mode ... and thus
this was a big problem to support kexec on ia64. And yet we still call
it, and ia64 can do kexec. So some other work around must have been
found. Can't immediately remember what it was though.
