pc-bios/s390-ccw: struct tpi_info must be declared as aligned(4)
I've run into a compilation error today with the current version of GCC 8: In file included from s390-ccw.h:49, from main.c:12: cio.h:128:1: error: alignment 1 of 'struct tpi_info' is less than 4 [-Werror=packed-not-aligned] } __attribute__ ((packed)); ^ cc1: all warnings being treated as errors Since the struct tpi_info contains an element ("struct subchannel_id schid") which is marked as aligned(4), we've got to mark the struct tpi_info as aligned(4), too.
