Comparing with kernel 2.6.25, AIM7 (use tmpfs) has more than 40% with 2.6.26-rc1
on my 8-core stoakley, 16-core tigerton, and Itanium Montecito. Bisect located
below patch.

After I manually reverted the patch against 2.6.26-rc1 while fixing lots of
conflictions/errors, aim7 regression became less than 2%.
