Date: Mon, 11 Sep 2006 07:10:28 +0200 From: Ingo Molnar <mingo@...e.hu> To: Jeremy Fitzhardinge <jeremy@...p.org> Cc: Andrew Morton <akpm@...l.org>, Andi Kleen <ak@...e.de>, Laurent Riffard <laurent.riffard@...e.fr>, Arjan van de Ven <arjan@...radead.org>, Kernel development list <linux-kernel@...r.kernel.org>, Jeremy Fitzhardinge <jeremy@...source.com> Subject: Re: 2.6.18-rc6-mm1: GPF loop on early boot Jeremy, another thing about i386-pda: why did you pick the %gs selector to store the PDA in? %fs would be a better choice because %gs is used by glibc so the saving/restoring of %fs would likely be near zero-cycles cost. (instead of the current 9 cycles for saving/restoring %gs) Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
