2d0bcfa331 gpu: nvgpu: add __must_check to gk20a_busy
The return value of gk20a_busy must be checked since it may not succeed
in some cases. Add the __must_check attribute that generates a compiler
warning for code that does not read the return value and fix all uses of
the function to take error cases into account.

28476a5b13 gpu: nvgpu: create new nvgpu ioctl header
Move nvgpu ioctls from the many user space interface headers to a new
single nvgpu.h header under include/uapi. No new code or replaced names
are introduced; this change only moves the definitions and changes
include directives accordingly.

719923ad9f gpu: nvgpu: rename gpu ioctls and structs to nvgpu
To help remove the nvhost dependency from nvgpu, rename ioctl defines
and structures used by nvgpu such that nvhost is replaced by nvgpu.
Duplicate some structures as needed.

Update header guards and such accordingly.

Proper error number for invalid request number is EINVAL instead of
EFAULT, so change it in ioctl calls.
