--- Comment #1 from Ian Lepore <ian@FreeBSD.org> ---
The ARM ARM, in a rare example of lucidity, describes the register parameter
for cp15 cache operations thusly: "When the data is stated to be an MVA, it
does not have to be cache line aligned.

If these changes lead to something working that doesn't work without the
changes, I guess we need to figure out why.  It may imply that the caller to
the function is incorrectly converting a start/end tulple to start/len or
something along those lines.
