As far as I know there are no far pointers in the Linux kernel.

Introducing U16 as an alias for __le16 is confusing since there is
already an 'u16' type in the Linux kernel. Please use the __le* types
directly.

Do all __le64 variables need four-byte alignment or only some of them?

Please use __le* directly instead of introducing the above aliases.
Please also follow the Linux kernel coding style (no space after '*').
