Nathan Whitehorn ae09ab8f63 Rework SLB trap handling so that double-faults into an SLB trap handler are ... possible, and double faults within an SLB trap handler are not. The result is that it possible to take an SLB fault at any time, on any address, for any reason, at any point in the kernel. This lets us do two important things. First, it removes the (soft) 16 GB RAM ceiling on PPC64 as well as any architectural limitations on KVA space. Second, it lets the kernel tolerate poorly designed hypervisors that have a tendency to fail to restore the SLB properly after a hypervisor context switch.
