powerpc: Fix oops when loading modules
This fixes a problem reported by Sean MacLennan where loading any module would cause an oops. We weren't marking the pages containing the module text as having hardware execute permission, due to a bug introduced in commit 8d1cf34e ("powerpc/mm: Tweak PTE bit combination definitions"), hence trying to execute the module text caused an exception on processors that support hardware execute permission. This adds _PAGE_HWEXEC to the definitions of PAGE_KERNEL_X and PAGE_KERNEL_ROX to fix this problem.
