From 33cf170715e87efd0608af6f2c056cafe0e7fc47 Mon Sep 17 00:00:00 2001 From: Bharata B Rao Date: Mon, 25 Nov 2019 08:36:25 +0530 Subject: [PATCH] mm: ksm: Export ksm_madvise() On PEF-enabled POWER platforms that support running of secure guests, secure pages of the guest are represented by device private pages in the host. Such pages needn't participate in KSM merging. This is achieved by using ksm_madvise() call which need to be exported since KVM PPC can be a kernel module.
