Arnd Bergmann 3fa8114be4 uaccess: fix nios2 and microblaze get_user_8()
[ Upstream commit a97b693c37 ]

These two architectures implement 8-byte get_user() through
a memcpy() into a four-byte variable, which won't fit.

Use a temporary 64-bit variable instead here, and use a double
cast the way that risc-v and openrisc do to avoid compile-time
warnings.

Fixes: 6a090e9797 ("arch/microblaze: support get_user() of size 8 bytes")
Fixes: 5ccc6af5e8 ("nios2: Memory management")
