From 5d3c8b21e22712137db6bbd246d1bdcbe0a09914 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 13 Feb 2008 16:20:35 +0100 Subject: x86: CPA: fix gbpages support in try_preserve_large_page [ mingo@elte.hu: while gbpages cannot be enabled on mainline currently, keep the code uptodate and this fix is easy enough. ] Use correct page sizes and masks for GB pages in try_preserve_large_page() This prevents a boot hang on a GB capable system with CONFIG_DIRECT_GBPAGES enabled.
