| * | gpu: nvgpu: Split vm_area management into vm code | Alex Waterman | 2017-05-19 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The vm_reserve_va_node struct is essentially a special VM area that can be used for sparse mappings and fixed mappings. The name of this struct is somewhat confusing (as node is typically used for list items). Though this struct is a part of a list it doesn't really make sense to call this a list item since it's much more. Based on that the struct has been renamed to nvgpu_vm_area to capture the actual use of the struct more accurately. This also moves all of the management code of vm areas to a new file devoted solely to vm_area management. Also add a brief overview of the VM architecture. This should help other people follow along the hierachy of ownership and lifetimes in the rather complex MM code.

| * | gpu: nvgpu: Split VM implementation out | Alex Waterman | 2017-05-19 |
| This patch begins splitting out the VM implementation from mm_gk20a.c and moves it to common/linux/vm.c and common/mm/vm.c. This split is necessary because the VM code has two portions: first, an interface for the OS specific code to use (i.e userspace mappings), and second, a set of APIs for the driver to use (init, cleanup, etc) which are not OS specific. This is only the beginning of the split - there's still a lot of things that need to be carefully moved around.
