OK, here it is. Benchmarks still coming. This is against Andi's 2.6.18-rc7-git3 tree, and replaces the patches between (and not including) i386-pda-asm-offsets and i386-early-fault. One patch is identical, one is mildly modified, the rest are re-implemented but inspired by Jeremy's PDA work. Thanks, Rusty. -- Help!

Hi Andi, This is a series of patches based on your latest queue (as of the other day, at least). It includes: - the most recent patch to compute the appropriate amount of percpu space to allocate, using a separate reservation for modules where needed. - make the percpu sections page-aligned, so that percpu variables can be page aligned if needed (which is used by gdt_page) -

Hi Jeremy, all, Sorry this took so long, spent last week in Japan at OSDL conf then netconf. After several false starts, I ended up with a very simple implementation, which clashes significantly with your work since then 8(. I've pushed the patches anyway, but it's going to be significant work for me to re-merge them, so I wanted your feedback first. The first patch simply changes
