Subject: riscv: stop calling page_address() in free_pages()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=5e8fce2016d1a863913265a9b5fcc2ecf1955067;p=users%2Fhch%2Fmisc.git

riscv: 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.
