* gpu: nvgpu: common: fix MISRA Rule 10.4Sai Nikhil2018-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | MISRA Rule 10.4 only allows the usage of arithmetic operations on operands of the same essential type category. Adding "U" at the end of the integer literals to have same type of operands when an arithmetic operation is performed. This fix violations where an arithmetic operation is performed on signed and unsigned int types. In balloc_get_order_list() the argument "int order" has been changed to a u64 because all callers of this function pass a u64 argument.

* gpu: nvgpu: Use new kmem API functions (common/*)Alex Waterman2017-03-26
| | | | | | | | | | | | | | | | | Use the new kmem API functions in common/* and common/mm/*. Add a struct gk20a pointer to struct nvgpu_allocator in order to store the gk20a pointer used for allocating memory.

* gpu: nvgpu: Move kmem_caches to allocatorAlex Waterman2017-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a single static kmem_cache for each type of data structure the allocators may want to allocate each allocator now has its own instance of the kmem_cache. This is done so that each GPU driver instance can accurately track how much memory it is using. In order to support this on older kernels a new NVGPU API has been made, nvgpu_kmem_cache_create(struct gk20a *g, size_t size) To handle the possibility that caches cannot be created with the same name. This patch also fixes numerous places where kfree() was wrongly used to free kmem_cache allocs.

* gpu: nvgpu: Move allocators to common/mm/Alex Waterman2017-01-09
Move the GPU allocators to common/mm/ since the allocators are common code across all GPUs. Also rename the allocator code to move away from gk20a_ prefixed structs and functions. This caused one issue with the nvgpu_alloc() and nvgpu_free() functions. There was a function for allocating either with kmalloc() or vmalloc() depending on the size of the allocation. Those have now been renamed to nvgpu_kalloc() and nvgpu_kfree().
