From 7679db85a8140b178b155a43ae8a8706bb478dc5 Mon Sep 17 00:00:00 2001 From: Qiuxu Zhuo Date: Wed, 14 Aug 2024 14:10:11 +0800 Subject: [PATCH] EDAC/igen6: Fix conversion of system address to physical memory address 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.
