Message-ID: <4A032EEC.30509@goop.org> Date: Thu, 07 May 2009 11:56:44 -0700 From: Jeremy Fitzhardinge <jeremy@...p.org> To: Linus Torvalds <torvalds@...ux-foundation.org> CC: Ingo Molnar <mingo@...e.hu>, the arch/x86 maintainers <x86@...nel.org>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Xen-devel <xen-devel@...ts.xensource.com> Subject: [PATCH 4/5] xen/i386: reserve Xen pagetables The Xen pagetables are no longer implicitly reserved as part of the other i386_start_kernel reservations, so make sure we explicitly reserve them. This prevents them from being released into the general kernel free page pool and reused.
