=== NVGPU_AS_IOCTL_MAP_BUFFER_EX ===
Map a memory region in the device address space. Identical to Linux driver pretty much.
On success, the mapped memory region is locked by having [[SVC#MemoryState]] bit34 set.
struct {
u32 __flags; // in, 4 works
u32 __kind; // in, -1 is default
u32 __nvmap_handle; // in
u32 __page_size; // inout, 0 means don't care
u64 __buffer_offset; // in
u64 __mapping_size; // in
u64 __offset; // out
};

Change channel's priority. Identical to Linux driver.
