* gpu: nvgpu: Remove <linux/mm.h> from the page allocatorAlex Waterman2017-05-14
| | | | | | | | | | | | | | | | | Remove the <linux/mm.h> include from the VIDMEM page allocator. To do this PAGE_SIZE needed to be defined for VIDMEM. Technically using the Linux PAGE_SIZE macro for VIDMEM was a bug since PAGE_SIZE need not be 4K on Linux so this patch also fixes a theoretical bug. Also usage of ERR_PTR(), PTR_ERR() and IS_ERR() was removed. These are Linux specific error handling macros.
