Use BUILD_BUG for compile-time check of invalid sizes passed
to get_user/put_user functions.

Implement the non-faulting kernel access helpers directly
instead of using uaccess routines under set_fs(KERNEL_DS).

There are no other remaining arch/arc specific callers of set_fs().
So just remove it and all the supporting code.
