From: Andi Kleen <andi@xxxxxxxxxxxxxx> The gcc LTO build can generate some extra weak source code file name symbols on the second kallsyms link like: 0000000002fdf20a W head64.c.552cf5a6 This causes the "Inconsistent kallsyms data" error due to mismatches in the stage1 vs stage2 kallsyms link. Filter those out when generating the System.map.
