m68k/uaccess: Revive 64-bit get_user()
Revive support for 64-bit get_user(), which was disabled in commit
d94af931af42152e ("[PATCH] m68k: clean up uaccess.h") due to a "broken"
typeof in (then brand new) gcc-4.1.
- Keep on using u64 for the temporary, as __typeof__() doesn't drop
the const qualifier,
- Move it into a union (like mips32 does) to get rid of the cast, as
using get_user() to fetch a __user pointer would cause a "cast to
pointer from integer of different size" warning otherwise.
