commit e40a01b0fb502629e345442ddb8feb07357c1de7 Author: Don Slutz <dslutz@xxxxxxxxxxx> AuthorDate: Thu Apr 3 15:07:09 2014 -0400 Commit: Ian Campbell <ian.campbell@xxxxxxxxxx> CommitDate: Fri Apr 4 09:28:09 2014 +0100 xenctx: Fix print_ctx_32on64's print_special call. print_special() uses the width argument to both select output format and array size. So by passing 4 it expects an array of uint32_t. But an array of uint64_t is passed. So copy and mask the registers to 32 bits.
