Fixes & Enhancements

Fixes
- It takes too long in the memory correctable Error-Correcting Code (ECC) logging System Management Interrupt
(SMI), which impacts the Omni-Path Architecture Host Fabric Interface (OPA HFI) network performance . Fixed it by
removing the redundant data logged to Serial Presence Detection (SPD) to reduce SMI time from hundreds to several
milliseconds.

Enhancements
- Updated the Intel Xeon Processor Scalable Family Processor Microcode to version 0x3A to address CVE-2017-5715 (http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2017-5715).
- CVE-2017-5753 and CVE-2017-5754 are addressed by Operating System & Hypervisor updates.
