mempolicy: rename struct mempolicy 'policy' member to 'mode'
The terms 'policy' and 'mode' are both used in various places to describe the semantics of the value stored in the 'policy' member of struct mempolicy. Furthermore, the term 'policy' is used to refer to that member, to the entire struct mempolicy and to the more abstract concept of the tuple consisting of a "mode" and an optional node or set of nodes. Recently, we have added "mode flags" that are passed in the upper bits of the 'mode' [or sometimes, 'policy'] member of the numa APIs. I'd like to resolve this confusion, which perhaps only exists in my mind, by renaming the 'policy' member to 'mode' throughout, and fixing up the Documentation. Man pages will be updated separately.

structure, struct mempolicy. Details of this structure will be discussed
in context, below, as required to explain the behavior.
- Note: in some functions AND in the struct mempolicy itself, the mode

Linux memory policy supports the following 4 behavioral modes:
Default Mode--MPOL_DEFAULT: The behavior specified by this mode is
