Hello,
I have already posted a patch fixing this. Please see:
https://lkml.org/lkml/2017/8/3/824
This makes the loop identical to the CPER code which prints the estatus
blocks to the kernel logs.
Thanks,
Tyler

The revision 0x300 generic error data entry is different with the old
version. when ghes_do_proc traverses to get the data entry, it does not
consider this difference. so when error status block has revision 0x300
data entry, it will have issue.
