2.6.30-stable review patch. If anyone has any objections, please let us know.
------------------ From: Weirich, Bernhard <bernhard.weir...@riedel.net> [I'm going to fix upstream differently, by having all CPU types actually support _PAGE_SPECIAL, but I prefer the simple and obvious fix for -stable. -- Ben] The test that decides whether to define __HAVE_ARCH_PTE_SPECIAL on powerpc is bogus and will end up always defining it, even when _PAGE_SPECIAL is not supported (in which case it's 0) such as on 8xx or 40x processors.
