Ingo Weinhold 74785e79db * Added "from" address space parameter to vm_swap_address_space()/ ... arch_vm_aspace_swap(). * The x86 implementation does now maintain a bit mask per vm_translation_map_arch_info indicating on which CPUs the address space is active. This allows flush_tmap() to avoid ICI for user address spaces when the team isn't currently running on any other CPU. In this context ICI is relatively expensive, particularly since we map most pages via vm_map_page() and therefore invoke flush_tmap() pretty much for every single page. This optimization speeds up a "hello world" compilation about 20% on my machine (KDEBUG turned off, freshly booted), but interestingly it has virtually no effect on the "-j2" haiku build time. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27912 a95241bf-73f2-0310-859d-f6bbb57e9c96		2008-10-07 21:39:19 +00:00
