Yes, that was 1.5 years ago (commit ac94a2911e84 ("s390: update defconfigs")). > So probably > CONFIG_MARCH_Z13 > CONFIG_MARCH_Z14 > CONFIG_MARCH_Z15 > CONFIG_MARCH_Z16 > > All look like they're still "supported" (and I'm guessing > CONFIG_MARCH_Z10 and CONFIG_MARCH_Z196 are not too much burden to > continue to maintain kernel support for), with a higher emphasis > perhaps on z15+z16? That makes sense. However for the kernel it doesn't make a difference if compiled for z15 or z16 - there were no general instructions added with z16 that would make any difference for the kernel. All new instructions that came with z16 are either only relevant for user space, or used via .insn notation in the kernel, and only used if some hardware feature is present.
