Bob Liu f67d9b1576 nommu: add page alignment to mmap ... Currently on nommu arch mmap(),mremap() and munmap() doesn't do page_align() which isn't consist with mmu arch and cause some issues. First, some drivers' mmap() function depends on vma->vm_end - vma->start is page aligned which is true on mmu arch but not on nommu. eg: uvc camera driver. Second munmap() may return -EINVAL[split file] error in cases when end is not page aligned(passed into from userspace) but vma->vm_end is aligned dure to split or driver's mmap() ops. Add page alignment to fix those issues.
