Subject: [PATCH] linux/types.h: always export 64bit aligned defines

Some kernel headers exported to userspace rely on these 64bit aligned defines.
However, they are hidden behind __KERNEL_STRICT_NAMES at the moment which
means most of the time, they're never actually available.  These these defines
dont actually conflict with normal userspace / C library types, there's no
reason to hide them behind the __KERNEL_STRICT_NAMES define.
