Nathan Whitehorn fca060b9f9 MFC r204297:
Move the OEA64 scratchpage to the end of KVA from the beginning, and set
its PVO to map physical address 0 instead of kernelstart. This fixes a
situation in which a user process could attempt to return this address
via KVM, have it fault while being modified, and then panic the kernel
because (a) it is supposed to map a valid address and (b) it lies in the
no-fault region between VM_MIN_KERNEL_ADDRESS and virtual_avail.

While here, move msgbuf and dpcpu back into regular KVA space for
consistency with other implementations.
