* gpu: nvgpu: Combine the fault buffer deinit seqsTerje Bergstrom2018-07-06
| | | | | | | | | | | | | | | | | | | | | | | gv11b_mm_fault_info_mem_destroy() and gv11b_mm_mmu_hw_fault_buf_deinit() serve a similar purpose of disabling hub interrupts and deinitializing memory related to MMU fault handling. Out of the two the latter was called from BAR2 deinitialization, and the former from nvgpu_remove_mm_support(). Combine the functions and leave the call from nvgpu_remove_mm_support(). This way BAR2 deinitialization can be combined with gp10b version.

| | | | | | | | | | | | | | | | Rename os/linux/vidmem.c to os/linux/dmabuf_vidmem.c.

Also move the header include/nvgpu/linux/vidmem.h to os/linux/dmabuf_vidmem.h. It does not expose any interface to outside Linux code.
