[Qemu-devel] [PATCH 05/19] Split cpu_mmu_index into cpu_mmu_index_data and cpu_mmu_index_code.

[Tristan Gingold <gingold@adacore.com>]

This is required by alpha system emulation as PAL mode disable instruction
mmu but not data mmu.
This might also be required for other cpus that have a split I/D mmu enable.
