From 6a22c57b8d2a62dea7280a6b2ac807a539ef0716 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 29 Oct 2007 11:36:04 -0700 Subject: Revert "x86_64: allocate sparsemem memmap above 4G" This reverts commit 2e1c49db4c640b35df13889b86b9d62215ade4b6. First off, testing in Fedora has shown it to cause boot failures, bisected down by Martin Ebourne, and reported by Dave Jobes. So the commit will likely be reverted in the 2.6.23 stable kernels. Secondly, in the 2.6.24 model, x86-64 has now grown support for SPARSEMEM_VMEMMAP, which disables the relevant code anyway, so while the bug is not visible any more, it's become invisible due to the code just being irrelevant and no longer enabled on the only architecture that this ever affected.
