This serie of patches supports userland mappings of SPE local stores using 64K hardware pages rather than 4K on a kernel using 4K pages to improve performances.Ben, I have problems porting these patches to powerpc.git#for-2.6.22. Could you port them yourself and submit them to Paul? What is the status of the second patch, do you have a version suitable for upstream?
I have more up to date versions of these, I'll do the port. The generic change needs to be done differently for upstream. I've been posting regulary a serie of patches that change get_unmapped_area() for that which I hope will get upstream but I yet to have some feedback from akpm... Ben.
