From: Nicholas Mc Guire <hofrat@osadl.org>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 5f508c43a7648baa892528922402f1e13f258bd4 upstream.
As kvm_mips_complete_mmio_load() did not yet modify PC at this point as James Hogans <james.hogan@imgtec.com> explained the curr_pc variable and the comments along with it can be dropped.
