alc ede2fb9751 In the common case, pmap_enter_quick() completes without sleeping. ... In such cases, the busying of the page and the unlocking of the containing object by vm_map_pmap_enter() and vm_fault_prefault() is unnecessary overhead. To eliminate this overhead, this change modifies pmap_enter_quick() so that it expects the object to be locked on entry and it assumes the responsibility for busying the page and unlocking the object if it must sleep. Note: alpha, amd64, i386 and ia64 are the only implementations optimized by this change; arm, powerpc, and sparc64 still conservatively busy the page and unlock the object within every pmap_enter_quick() call. Additionally, this change is the first case where we synchronize access to the page's PG_BUSY flag and busy field using the containing object's lock rather than the global page queues lock. (Modifications to the page's PG_BUSY flag and busy field have asserted both locks for several weeks, enabling an incremental transition.)		2004-12-15 19:55:05 +00:00
