Thank you Ben. Then, how about this?
azfs_mmap(struct file *file, struct vm_area_struct *vma) { ... ... ... #ifdef CONFIG_PPC pgprot_t page_prot; #endif ... ... ... #ifdef CONFIG_PPC page_prot = pgprot_val(vma->vm_page_prot); page_prot |= (_PAGE_NO_CACHE | _PAGE_RW); page_prot &= ~_PAGE_GUARDED; vma->vm_page_prot = __pgprot(page_prot); #else vma->vm_page_prot = pgprot_noncached(vma->vm_page_prot); #endif ... ... ...
