我对这里不了解。sev = ghes_severity(estatus->error_severity);和sec_sev = ghes_severity(gdata->error_severity);有什么差异,为什么要把前者改成后者，后续新增的代码是为什么又用前者?

这里内核的处理是有问题的，即使不加入zhaoxin patch code，这里也应该是使用sec_sev。sev是一个总的severity，是ghes中各个error的severity的最高值，而在arch_apei_report_mem_error时应该是针对各个具体的error。
而后面的代码，使用sev是合理的，所以不需要修改。

这方面您们CPU厂商可能会更专业一些，既然如此建议将这个改动单独拆分成一个提交，并且看起来也可以提给上游

新版本中已经拆分出来了，还烦请review了。后续会考虑向上游主线提交。
When executing arch_apei_report_mem_error, replace the previous 'sev'with 'sec_sev'. 'sev' represents the overall severity, which is the highest severity among individual errors in GHES. However, during arch_apei_report_mem_error, it should be specific to each individual error. Signed-off-by: leoliu-oc <leoliu-oc@zhaoxin.com>
zhaoxin inclusion category: bugfix ------------------- The mcelog cannot decode PCIE, ZDI/ZPI, and DRAM errors in the FFM (Firmware First Mode). The purpose of this patch is to enable mcelog to decode PCIE, ZDI/ZPI, and DRAM errors that occur on Zhaoxin processors, so that the cause of these errors can be quickly located.
