Microcode update for i7-620LM (CPUID 20655)

Hi,

according to this Microcode Update Document: https://newsroom.intel.com/wp-content/uploads/sites/11/2018/04/microcode-update-guidance.pdf, an updated microcode should be available for Arrandale Core i7-620LM (CPUID 20655 => 06-25-05) as its status is now PRODUCTION at revision 0x6.

In the latest version of Linux* Processor Microcode Data File (20180312) https://downloadcenter.intel.com/download/27591/Linux-Processor-Microcode-Data-File?product=873  available for download, that update doesn't seem included. How is it possible to obtain it?

Relevant /proc/cpuinfo data:

vendor_id : GenuineIntel

cpu family : 6

model : 37

model name : Intel(R) Core(TM) i7 CPU       L 620  @ 2.00GHz

stepping : 5

microcode : 4

Thanks,

Eric
