- * As a performance optimization, other platforms preserve the fixmap mapping
- * across a context switch, we don't presently do this, but this could be done
- * in a similar fashion as to the wired TLB interface that sh64 uses (by way
- * of the memory mapped UTLB configuration) -- this unfortunately forces us to
- * give up a TLB entry for each mapping we want to preserve. While this may be
- * viable for a small number of fixmaps, it's not particularly useful for
- * everything and needs to be carefully evaluated. (ie, we may want this for
- * the vsyscall page).
- *
- * XXX: Perhaps add a _PAGE_WIRED flag or something similar that we can pass
- * in at __set_fixmap() time to determine the appropriate behavior to follow.
