Hi,
shared mmap. This is the important one. Since we have a logical
backing store this is easy to handle. We just enforce that the
virtual address in a process that we mmap something to must match the
logical address to VIRT_INDEX_BITS. The effect is the same as a
larger page size
At least for sparc it's already supported. Right now I don't feel like
looking into the 2.4 solution but checkout srmmu_vac_update_mmu_cache in

Not yet. A good test of shared mmap coherency is a recent samba
