From 7187dafc1e7fde551001ba91ea94cf6faa73256a Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 25 Jul 2012 21:19:48 +0000 Subject: [PATCH] powerpc/crypto: Remove users of virt_to_abs() and phys_to_abs() in nx crypto driver phys_to_abs() is a nop, don't use it. virt_to_abs() is just a wrapper around __pa(), call __pa() directly.
