Add a kernel-doc comment in kernel.h to document the macro
`u64_to_user_ptr`.

We refer functions as func(), so `u64_to_user_ptr` --> u64_to_user_ptr().

As of today, this macro is mentioned in the documentation in
'ioctl.rst' and 'botching-up-ioctls.rst'

Missing period at the end.

...

+/**
+ * u64_to_user_ptr - convert an unsigned 64bit number into a user pointer

64-bit

+ * @x: the number to convert

Isn't 'number' is a bit misleading here?
It decodes the user pointer, that is encoded into unsigned 64-bit value.
Unfortunately I am not a native speaker, I can't propose anything better.
It might be that the 'number' is quite good choice, dunno.

I agree about the macro's purpose. However, it does its job even if the 64-bit
value isn't a valid pointer (and this is what you will get). For this reason I
used a generic "number".
