Subject: [PATCH v2] 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.
