* [PATCH] Zone reclaim: Reclaim logicChristoph Lameter2006-01-185-8/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some bits for zone reclaim exists in 2.6.15 but they are not usable. This patch fixes them up, removes unused code and makes zone reclaim usable. Zone reclaim allows the reclaiming of pages from a zone if the number of free pages falls below the watermarks even if other zones still have enough pages available. Zone reclaim is of particular importance for NUMA machines. It can be more beneficial to reclaim a page than taking the performance penalties that come with allocating a page on a remote zone. Zone reclaim is enabled if the maximum distance to another node is higher than RECLAIM_DISTANCE, which may be defined by an arch. By default RECLAIM_DISTANCE is 20. 20 is the distance to another node in the same component (enclosure or motherboard) on IA64. The meaning of the NUMA distance information seems to vary by arch. If zone reclaim is not successful then no further reclaim attempts will occur for a certain time period (ZONE_RECLAIM_INTERVAL). This patch was discussed before.

* [PATCH] Zone reclaim: resurrect may_swapChristoph Lameter2006-01-181-0/+7
| | | | | | | | | | | | | | | Zone reclaim has a huge impact on NUMA performance (f.e. our maximum throughput with XFS is raised from 4GB to 6GB/sec / page cache contamination of numa nodes destroys locality if one just does a large copy operation which results in performance dropping for good until reboot).

* [PATCH] mm: migration page refcounting fixNick Piggin2006-01-187-75/+76
| | | | | | | | | | | | | | | | | Migration code currently does not take a reference to target page properly, so between unlocking the pte and trying to take a new reference to the page with isolate_lru_page, anything could happen to it. Fix this by holding the pte lock until we get a chance to elevate the refcount. Other small cleanups while we're here.

* [PATCH] Prevent trident driver from grabbing pcnet32 hardwareJon Mason2006-01-181-10/+8
| | | | | | | | | | | | | | | | Some pcnet32 hardware erroneously has the Vendor ID for Trident. The pcnet32 driver looks for the PCI ethernet class before grabbing the hardware, but the current trident driver does not check against the PCI audio class. This allows the trident driver to claim the pcnet32 hardware. This patch prevents that. This revised version of the OSS Trident patch includes PCI_DEVICE Macro usage.
