powerpc/mm: Fix _PAGE_COHERENT support on classic ppc32 HW
The following commit: commit 64b3d0e8 Author: Benjamin Herrenschmidt <benh@kernel.crashing.org> Date: Thu Dec 18 19:13:51 2008 +0000 powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDED broke setting of the _PAGE_COHERENT bit in the PPC HW PTE. Since we now actually set _PAGE_COHERENT in the Linux PTE we shouldn't be clearing it out before we propogate it to the PPC HW PTE. Reported-by:Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by:
