Ingo Weinhold 9a42ad7a77 When switching to a kernel thread we no longer set the page directory. ... This is not necessary, since userland teams' page directories also contain the kernel mappings, and avoids unnecessary TLB flushes. To make that possible the vm_translation_map_arch_info objects are reference counted now. This optimization reduces the kernel time of the Haiku build on my machine with SMP disabled a few percent, but interestingly the total time decreases only marginally. Haven't tested with SMP yet, but for full impact CPU affinity would be needed. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28287 a95241bf-73f2-0310-859d-f6bbb57e9c96		2008-10-22 15:12:32 +00:00
