Subject: [PATCH AUTOSEL 5.10 13/13] mksysmap: Fix the mismatch of 'L0' symbols in System.map

From: Youling Tang <tangyouling@...ngson.cn>

[ Upstream commit c17a2538704f926ee4d167ba625e09b1040d8439 ]

When System.map was generated, the kernel used mksysmap to filter the
kernel symbols, we need to filter "L0" symbols in LoongArch architecture.

$ cat System.map | grep L0
9000000000221540 t L0

The L0 symbol exists in System.map, but not in .tmp_System.map. When
"cmp -s System.map .tmp_System.map" will show "Inconsistent kallsyms
data" error message in link-vmlinux.sh script.
