as it stands, this breaks all non-arm NOMMU ports. the patch will need to be broken up into arm-specific and arm-independent parts.
ok, I can do that.
the common code changes will need justification as to why they exist at all. we're doing MPU on Blackfin/nommu today without any of these. we support pretty much all the same features of a MMU system short of virtual memory -- 4k pages, RWX granularity, process to process protection, process to kernel protection (include kernel modules), kernel XIP, and userspace XIP. further, why did you go with CONFIG_CPU_CP15_MPU ? there is already a CONFIG_MPU option that is used in common nommu code.
which tree has CONFIG_MPU, and the MPU support for blackfin? There is no such thing in the 888 uclinux release tree.
I don't know which repo I should be developing under. I suppose it should be the git tree that people are posting patches against in the uclinux-dev list. Which tree is that?
