46559e8184 target/hppa: Only use EXCP_DTLB_MISS 
Unknown why this works, but if we return EXCP_ITLB_MISS we
will triple-fault the first userland instruction fetch.
Is it something to do with having a combined I/DTLB?

The TLB can now be populated, but it cannot yet be cleared.

650cdb2a2e target/hppa: Implement tlb_fill 
However since HPPA has a software-managed TLB, and the relevant
TLB manipulation instructions are not implemented, this does not
actually do anything.

813dff13bf target/hppa: Skeleton support for hppa-softmmu 
With the addition of default-configs/hppa-softmmu.mak, this
will compile.  It is not enabled with this patch, however.
