Scott Wood f67f4ef5fc powerpc/book3e-64: use a separate TLB handler when linear map is bolted ... On MMUs such as FSL where we can guarantee the entire linear mapping is bolted, we don't need to worry about linear TLB misses. If on top of that we do a full table walk, we get rid of all recursive TLB faults, and can dispense with some state saving. This gains a few percent on TLB-miss-heavy workloads, and around 50% on a benchmark that had a high rate of virtual page table faults under the normal handler. While touching the EX_TLB layout, remove EX_TLB_MMUCR0, EX_TLB_SRR0, and EX_TLB_SRR1 as they're not used.
