It does work on all pa20 processors, afaik. Let me rephrase:
"Be aware that, if atlas relies on being able to prefetch invalid
addresses and have that not fault, then it will only work on some PA
processors but not all of them. All pa20 processors should work.
pa11 processors will not."
We ran into this while trying to get PA7300LC to do prefetching in the
kernel.
