At 8k per TLB (for 64-bit host or target), 8 or more modes make the TLBs bigger than 64k, and some RISC TCG backends do not like that. On the affected hosts, cut the TLB size in half---there is still a measurable speedup on PPC with the next patch. Signed-off-by: Paolo Bonzini <address@hidden> Message-Id: <address@hidden>
