From 35fec26242bd3ff5a770789185852d27b44ffaec Mon Sep 17 00:00:00 2001 From: James Hogan Date: Thu, 9 Jun 2016 14:19:21 +0100 Subject: [PATCH] MIPS: KVM: Use va in kvm_get_inst() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Like other functions, make use of a local unsigned long va, for the virtual address of the PC. This reduces the amount of verbose casting of the opc pointer to an unsigned long.
