SVN rev 190067 on 2009-03-19 15:32:16Z by marius
MFC: r185007
Use the spitfire VIS block copy/zero functions also with cheetah-
class CPUs. In theory one could also use versions additionally
taking advantage of the prefetch cache with cheetah-class CPUs,
in my worldstone runs these either didn't provide extra speedup
(USIII+) in comparison to the existing spitfire versions or were
even slightly slower (USIIIi) though, so they aren't committed
for now.
The basic problem leading to the VIS-based copy/zero functions
being initially disabled for cheetah-class CPUs was solved by
letting cheetah_init() clear DCR_IFPOE.
