[PATCH] vmalloc_to_page helper
After William did the remap_pfn_range change, a very common pattern became:
page = page_to_pfn(vmalloc_to_page((void *)pos));
if (remap_pfn_range(vma, start, page, PAGE_SIZE, PAGE_SHARED)) {
the patch below adds a very simple helper, vmalloc_to_pfn() to simplify this
a bit.
