Currently, the unprivilege load/store functions are inline functions. We will be extending these functions to track whether a page/access fault occurs when we execute unprivilege load/store instruction. To make things simpler and debugable, we reduce number of places which can potentially generate a page/access fault by making all unprivilege load/store functions as regular (non-inline) functions.
