From 08278452325454027c6d42bc2d687dc8dd518006 Mon Sep 17 00:00:00 2001
From: "H. Peter Anvin" <hpa@linux.intel.com>
Date: Tue, 29 May 2012 14:08:11 -0700
Subject: [PATCH] relocs: Move stop to the end

The Linux kernel puts the stop word at the beginning of the relocation
list (the list is processed backwards); Syslinux puts the stop word at
the beginning of the relocation list (the list is processed forwards.)

Missed that change when syncing with the kernel version.

(plus everything to actually make this get built... -- pjones)

From e1db3e675ae4ccbeea5de9f4b74a618e42eac1a3 Mon Sep 17 00:00:00 2001
From: Nick Bertrand <nick@physics.umn.edu>
Date: Tue, 31 Jul 2012 19:00:05 -0700
Subject: [PATCH] Save Dell BIOS chunk in PXELINUX

Our site has many Dell OptiPlex 790s, all of which are unable to use the
'localboot' PXELINUX option as they either hang at 'Booting from local disk...'
or immediately reboot depending on which SYSLINUX version is used. Many people
have suggested using chain.c32 to chain load the local disk as a workaround,
but this causes problems with Windows 7 BitLocker as it detects the chain load
and forces the user to enter the recovery key. While searching for another
option I determined that the problem seems to stem from the BIOS storing some
information in the memory range 0x47CC-0x47FF, which is overwritten when
PXELINUX loads. I couldn't figure out a clean way to avoid that memory region
as it falls in the middle of the 4.x bss16 region, so I decided to create a
copy of it instead. By copying that information out of the way during PXELINUX
initialization and copying it back before returning control via 'localboot 0',
the computer successfully boots to the local disk.

Some additional info:

BIOS revision: A13
PXE versions: Intel Boot Agent GE v1.3.81, Intel Boot Agent PXE Base Code (PXE-2.1 build 089)
Versions of SYSLINUX affected: 3.83, 4.03, 4.04, 4.05, possibly others
Resulting symptom for localboot option vs SYSLINUX version:

localboot 0 localboot -1
3.83 Reboot Reboot
4.03 Reboot Reboot
4.04 Hang Reboot
4.05 Hang Reboot

This patch does not fix the reboot issue when using 'localboot -1'. I believe
this patch should also help those with OptiPlex 990s, but I don't have one to
test with to confirm.

Below is a patch against commit 0a0e0e41cad93cd16c323cf16f40264a21eedd6c of
the git.kernel.org/pub/scm/boot/syslinux/syslinux.git repository.

Subject: [PATCH] libinstaller: Avoid using <linux/ext2_fs.h>

Don't use <linux/ext2_fs.h> if we can avoid it.

The ioctl constants have been globalized and moved to <linux/fs.h>.
Use a private copy of ext2_fs.h from e2fsprogs with the ioctl
constants removed for the data structures.

Do at least attempt backward compatibility for old kernel headers, but
no real hope of proper operation there...

Subject: isohybrid: Generate MBR even when in EFI mode

Various EFI systems insist that there be no active flag in the pMBR in
order to parse the GPT. The only way around this is to also generate a
valid MBR - the firmware will then pick that up and use the system
partition provided there. In order to deal with other EFI "sanity" checks,
the partition type for the non-EFI partitions is set to 0 to skip the
firmware bailing because of overlapping partitions.
