From 54ac8fcbd6e6777929235ac767467991005d2df3 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 4 Aug 2017 19:23:53 +0200 Subject: parisc: PDT: Add full support for memory failure via Page Deallocation Table (PDT) This patch adds full support to read PDT info on all machine types. At bootup the PDT is read and bad memory excluded from usage via memblock_reserve(). Later in the boot process a kernel thread is started (kpdtd) which regularily checks firmare for new reported bad memory and tries to soft offline pages in case of correctable errors and to kill processes and exclude such memory in case of uncorrectable errors via memory_failure().
