Understood, but I'm going to start looking in the way Rusty and Arnd suggested with the vmalloc approach. This would allow for saving of memory and dynamic allocation of module memory making it more robust. And all this without that evil extra indirection!
Remember that this approach could effectively just move the indirection to the TLB / page tables (well, I say "moves" because large kernel mappings are effectively free compared with 4K mappings). So be careful about coding up a large amount of work before unleashing it: I doubt you'll be able to find a solution that doesn't involve tradeoffs somewhere (but wohoo if you can). -- SUSE Labs, Novell Inc.Send instant messages to your online friends http://au.messenger.yahoo.com -
