From 26ee17ff71d3def831bfa4f6851ed1ba789e24f6 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Thu, 9 Jun 2016 14:19:13 +0100 Subject: [PATCH] MIPS: KVM: Drop unused hpa0/hpa1 args from function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The function kvm_mips_handle_mapped_seg_tlb_fault() has two completely unused pointer arguments, hpa0 and hpa1, for which all users always pass NULL. Drop these two arguments and update the callers.
