From 56a3f30e029396948989b96716f27b87e3510e0f Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Tue, 20 Oct 2015 14:59:20 +0100 Subject: [PATCH] arm64: Make 36-bit VA depend on EXPERT Commit 215399392fe4 (arm64: 36 bit VA) introduced 36-bit VA support for the arm64 kernel when the 16KB page configuration is enabled. While this is a valid hardware configuration, it's not something we want to encourage since it reduces the memory (and I/O) range that the kernel can access. Make this depend on EXPERT to avoid complaints of Linux not mapping the whole RAM, especially on platforms following the ARM recommended memory map.
