From: Qiuxu Zhuo <qiuxu.zhuo@xxxxxxxxx>
commit 0ad875f442e95d69a1145a38aabac2fd29984fe3 upstream.
The conversion of system address to physical memory address (as viewed by
the memory controller) by igen6_edac is incorrect when the system address
is above the TOM (Total amount Of populated physical Memory) for Elkhart
Lake and Ice Lake (Neural Network Processor). Fix this conversion.
