Hello, I found the cause of the problem. My architecture does not define the _PAGE_SPECIAL macro, thus in pte-common.h line 32, it is defined as 0 And then in line 180, since _PAGE_SPECIAL is defined, the macro __HAVE_ARCH_PTE_SPECIAL is erroneously defined. This makes any ppc architecture to act as if it has a pte special bit! I suggest the following simple patch to fix this.
