arm64,loongarch64上crash解析vmcore时ps命令执行时报错

**【缺陷描述】：arm64,loongarch64上crash解析vmcore时ps命令执行时报错**

**一、缺陷信息**

**【缺陷所属的os版本】openEuler 24.03 (LTS-SP1)**

**【内核版本】6.6.0-89.0.0.94.oe2403sp1.aarch64   6.6.0-72.0.0.76.oe2403sp1.loongarch64**

**【缺陷所属软件及版本号】 crash-8.0.4-10.oe2403sp1.aarch64 crash-8.0.4-10.oe2403sp1.loongarch64**

**【环境信息】**
软件信息

kexec-tools-2.0.26-9.oe2403sp1.aarch64
kernel-6.6.0-89.0.0.94.oe2403sp1.aarch64
crash-8.0.4-10.oe2403sp1.aarch64

kexec-tools-2.0.26-11.loongarch64
kernel-6.6.0-72.0.0.76.oe2403sp1.loongarch64
crash-8.0.4-10.oe2403sp1.loongarch64

**【问题复现步骤】：**
1. echo c > /proc/sysrq-trigger #手动触发kdump生成vmcore
2. 使用crash解析vmcore，执行ps命令

**【实际结果】**
执行ps命令时有如下报错，进程显示不完整
