2011-11-30video: tegra: nvmap: single page allocation policy correctedKirill Artamonov
When user doesn't use default heap policy and selects GART or carveout allocation, automatic single-page-to-sysmem rule doesn't work. Because of broken rule many single page allocations take extra space in carveout and create unnecessary page mappings in GART and SMMU. The fix adds sysmem bit to heap mask when allocation is single page and GART or carveout is present in heap mask. bug 730124 bug 731923 The change also does sanity check of available system memory before adding sysmem bit for carveout allocations. bug 777839 Original-Change-Id: I13a62653825f6c80581adcd2682fb2608d3a284e Reviewed-on: http://git-master/r/31383 Reviewed-by: Kirill Artamonov <kartamonov@nvidia.com> Tested-by: Kirill Artamonov <kartamonov@nvidia.com> Reviewed-by: Krishna Reddy <vdumpa@nvidia.com> Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com> Rebase-Id: R278606210f20aacc885fa9eb06b3a2a3d8677b55

Processes are killed in order of priority from lowest to highest, and then from largest to smallest users.

2011-11-30video: tegra: nvmap: Clear handle->owner on releaseRobert Morell
A struct nvmap_handle may be shared by multiple clients. If the original client (the handle "owner") is destroyed, but the handle is still referenced by other clients, h->owner points to freed memory. To prevent this, clear h->owner when the owner frees its reference to that struct nvmap_handle.

2011-11-30video: tegra: nvmap: Fix handle ref countingRebecca Schultz Zavin
In the current implementation handles hold references to a client and clients hold references to their handles. As a result when a process terminates it's handles can't be cleaned up and we leak memory. Instead only hold references to handles from clients.
