Can we give hugetlb demand faulting a spin in the mm tree? And could people with alpha, sparc, and ia64 machines give them a good spin? I haven't been able to test those arches yet. -Thanks - htlb-get_user_pages removes an optimization that is no longer valid when demand faulting huge pages - htlb-fault moves the fault logic from hugetlb_prefault() to hugetlb_pte_fault() and find_get_huge_page(). - htlb-acct adds an overcommit check to maintain the no-overcommit semantics provided by hugetlb_prefault() -- Adam Litke - (agl at us.ibm.com) IBM Linux Technology Center From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from westrelay02.boulder.ibm.com (westrelay02.boulder.ibm.com [9.17.195.11]) by e36.co.us.ibm.com (8.12.11/8.12.11) with ESMTP id j8SKOZjY012756 for ; Wed, 28 Sep 2005 16:24:35 -0400 Received: from d03av03.boulder.ibm.com (d03av03.boulder.ibm.com [9.17.195.169]) by westrelay02.boulder.ibm.com (8.12.10/NCO/VERS6.7) with ESMTP id j8SKPln9426668 for ; Wed, 28 Sep 2005 14:25:47 -0600 Received: from d03av03.boulder.ibm.com (loopback [127.0.0.1]) by d03av03.boulder.ibm.com (8.12.11/8.13.3) with ESMTP id j8SKPlS2032515 for ; Wed, 28 Sep 2005 14:25:47 -0600 Subject: [PATCH 0/3] Demand faulting for huge pages From: Adam Litke Content-Type: text/plain Date: Wed, 28 Sep 2005 15:25:41 -0500 Message-Id: <1127939141.26401.32.camel@localhost.localdomain> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org Return-Path: To: akpm@osdl.org Cc: "ADAM G.
