Description (last modified by Jakub Jermář)

The mips32 loader needs to establish cache coherence after it copies the kernel and other components around memory (corner case of self modifying code).

arm32 already does the right thing.

sparc64 already does the right thing.

ppc32 seems to flush something, but the issue still needs to be investigated/confirmed.

ia64, as of now, does not relocate neither the kernel nor the components so the caches are coherent.
