Date: Tue, 7 Feb 2012 16:25:27 -0800 From: Olof Johansson <olof@...om.net> To: x86@...nel.org, hpa@...or.com, mingo@...e.hu, tglx@...utronix.de Cc: linux-kernel@...r.kernel.org, matt.fleming@...el.com, mjg@...hat.com Subject: [PATCH v4 0/5] [RESEND] x86: efi: cleanups and basic 32/64-bit support This series allows basic booting of a 32-bit kernel on 64-bit EFI and vice versa. It's needed by Chrome OS, and we've been carrying a nasty hack to do it that I've cleaned up and made sure it works in both directions. Tested on Chrome OS for 64-bit EFI 32-bit kernel. Tested with an old MacBook for 32-bit EFI, 64-bit kernel. Note that this is required, but not sufficient, for full platform support for EFI in a mixed environment. There is no handling of runtime services, and no thunking for going in and out of firmware in a different mode. Resend of the last posted version. Acked by Matt, and Matthew seems to be OK with it as well (see http://marc.info/?l=linux-kernel&m=132578786105542). Please consider for 3.4 merge window. Thanks! -Olof Changelog is: v4: * Removed bogus memdesc warning printout * Fixed up printk formatting, removing redundant EFI output * Some of the earlier cleanup was accidentally reverted by this patch, fixed. * Reworded some messages to not have to line wrap printk strings v3: * Reorganized to a series of patches to make it easier to review, and do some of the cleanups I had left out before. v2: * Added graceful error handling for 32-bit kernel that gets passed EFI data above 4GB. * Removed some warnings that were missed in first version. -- 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/
