From 2792107dc3af29ecc1a9b3dc5bc873dac4b61cd6 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Wed, 24 Apr 2019 16:24:12 +0300 Subject: x86/Kconfig: Deprecate DISCONTIGMEM support for 32-bit x86 Mel Gorman says: "32-bit NUMA systems should be non-existent in practice. The last NUMA system I'm aware of that was both NUMA and 32-bit only died somewhere between 2004 and 2007. If someone is running a 64-bit capable system in 32-bit mode with NUMA, they really are just punishing themselves for fun." Mark DISCONTIGMEM broken for now as suggested by Christoph Hellwig, and (hopefully) remove it in a couple of releases.
