Actually, no. We only do that with the kernel code mapping which should be

Er, what? Assuming the TLB will retain some mappings while you
overwrite the pagetable is a highly dubious prospect. Are you copying
the same values over, or something else?
As long as a relocatable kernel is not used to restore a non-relocatable one
(or vice versa), we're copying the same values over.
So that case is deliberately considered broken?
