I found that too, and then noticed it is already fixed in linux-next:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=14cf9451be78f8a
Ard points out that most of the other ones are pointers to const data, which
are not a problem. This leaves the arm put_user bug as the only definite
problem that needs to be addressed in older kernels.
The three arch/riscv instances of 'const register unsigned long gp __asm__
("gp")' are different because they are never passed into an inline assembly as
far as I can tell. This seems to be unsupported for local register variables
according to the gcc documentation, but if that's a problem, it's unrelated to
this bug.
