| H A D | tlb.c | dcc17d1b Mon Oct 31 15:44:47 CST 2005 Peter Keilty <peter.keilty@hp.com> [IA64] Use bitmaps for efficient context allocation/free
Corrects the very inefficent method of finding free context_ids in
get_mmu_context(). Instead of walking the task_list of all processes,
2 bitmaps are used to efficently store and lookup state, inuse and
needs flushing. The entire rid address space is now used before calling
wrap_mmu_context and global tlb flushing.
Special thanks to Ken and Rohit for their review and modifications in
using a bit flushmap.
