Subject: powerpc: stop calling page_address() in free_pages()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c6686616b4e48de69f790c4b4d61fda9d76c0e25;p=users%2Fjedix%2Flinux-maple.git

powerpc: stop calling page_address() in free_pages()

free_pages() should be used when we only have a virtual address.  We
should call __free_pages() directly on our page instead.
