[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v9 18/18] 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.
