 What's wrong with cacheflush(addr, count, which) that actually checks if
<addr; addr+count> lies within the caller's address space before
performing the flush and returns -EPERM otherwise?  It would make the
caller crawl like a turtle if it wished to but it would leave other
processes alone. 

cacheflush(2) actually is supposed to handle things that way.

 Didn't I write it clearly-enough? ;-) 

return -EOVERBLOODINCAFFEIN;
