From: Baoquan He <bhe@xxxxxxxxxx>
Kernel commit 464920104bf7 (/proc/kcore: update physical address for
kcore ram and text) provides physical address of direct mapping kcore
program segments. So no need to calculate it specifically now. And the
old code is not correct since it calls vaddr_to_paddr() which has not
been ready at that time.
