Subject: [PATCH] Disable PIE to avoid FTBFS on amd64
gcc 6.x has PIE support enabled by default, which causes a build issue
with syslinux. This patch disables PIE support in the relevant
syslinux Makefile.

Subject: [PATCH] bios: Don't try to guess the sections alignment
For the compression / decompression to succeed, the sections layout must
be the same between the virtual memory and load memory. The section
alignment was kept in sync by introducing aligment that should be
greater or equal to the actual section alignment.
This patch compute the load memory addresses of the sections so that
the layout is the same as the virtual memory addresses.

From a14b1b3d3e375d2e8af8804171ef5e52574dbb2a Mon Sep 17 00:00:00 2001
From: "H. Peter Anvin" <hpa@zytor.com>
Date: Tue, 9 Feb 2016 18:15:50 -0800
Subject: [PATCH] core: Clean up the i386-bios build
Remove symbols and data structures not used in the i386-bios build,
and clean up the linker script so that most internal symbols are
HIDDEN.
Signed-off-by: H. Peter Anvin <hpa@zytor.com>
Upstream: ff859050fa4e6535cae098dc35d88a265466448d
This patch fixes the following build failure with i386 binutils 2.28.1:

--no-omagic \
> ldlinux.map
/builds/arnout/buildroot/output/host/bin/i586-buildroot-linux-uclibc-ld: ldlinux.elf: Not enough room for program headers, try linking with -N

Subject: [PATCH] extlinux: pull in sys/sysmacros.h for major/minor/makedev
These functions are defined in sys/sysmacros.h, so add the include to
main.c. This is already handled correctly in mountinfo.c. Otherwise
we get build failures like:

This fixes the following build error with newer binutils:
objcopy -O binary mbr.elf mbr.bin
perl /build/syslinux/src/syslinux/mbr/checksize.pl mbr.bin
mbr.bin: too big (452 > 440)
Corresponding bug reports:
- https://bugs.archlinux.org/task/60405
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=906414
Strips the .note.gnu.property in the linker scripts for the MBRs.

Do not include efisetjmp.h on efi.h
People than really want to use efisetjmp implementation can include
the header on their own.
