From: Shiju Jose <shiju.jose@huawei.com>
Add support to log and record the CXL poison events.
The corresponding Kernel patches here:
https://lore.kernel.org/linux-cxl/de11785ff05844299b40b100f8e0f56c7eef7f08.1674070170.git.alison.schofield@intel.com/
Presently RFC draft version for logging, could be extended for the policy
based recovery action for the frequent poison events depending on the above
kernel patches.

From: Shiju Jose <shiju.jose@huawei.com>
Add support to log and record the CXL AER uncorrectable errors.
The corresponding Kernel patch here:
https://patchwork.kernel.org/project/cxl/patch/166974413388.1608150.5875712482260436188.stgit@djiang5-desk3.ch.intel.com/
It was found that the header log data to be converted to the
big-endian format to correctly store in the SQLite database likely
because the SQLite database seems uses the big-endian storage.
