sys/i386/i386 pmap.c
Log:
Annotate pmap_changebit() as __always_inline. This function was
written as a template that when inlined is specialized for the caller
through constant value propagation and dead code elimination. Thus,
the specialized code that is generated for pmap_clear_reference() et
al. avoids several conditional branches inside of a loop.
