[PATCH] mark several functions __always_inline

      Arjan van de Ven <arjan@infradead.org>

Mark a number of functions as 'must inline'.  The functions affected by this
patch need to be inlined because they use knowledge that their arguments are
constant so that most of the function optimizes away.  At this point this
patch does not change behavior, it's for documentation only (and for future
patches in the inline series)
