Alan Cox c65205a6e2 Merge r216333 and r216555 from the native pmap ... When r207410 eliminated the acquisition and release of the page queues lock from pmap_extract_and_hold(), it didn't take into account that pmap_pte_quick() sometimes requires the page queues lock to be held. This change reimplements pmap_extract_and_hold() such that it no longer uses pmap_pte_quick(), and thus never requires the page queues lock. Merge r177525 from the native pmap Prevent the overflow in the calculation of the next page directory. The overflow causes the wraparound with consequent corruption of the (almost) whole address space mapping. Strictly speaking, r177525 is not required by the Xen pmap because the hypervisor steals the uppermost region of the normal kernel address space. I am nonetheless merging it in order to reduce the number of unnecessary differences between the native and Xen pmap implementations. Tested by: sbruno		2011-12-30 18:16:15 +00:00
