Subject: [PATCH] powerpc/pseries: lparcfg don't include slb_size line in radix
mode
References: bsc#1204413 ltc#200176
Patch-mainline: v5.17-rc1
Git-commit: 3d3282fd34d82caac5005d9c4d4525054eb3cac1
This avoids a change in behaviour in the later patch making hash
support configurable. This is possibly a user interface change, so
the alternative would be a hard-coded slb_size=0 here.
