Subject: [PATCH] ieee1275: check for IBM pseries emulated machine
As there is no check for IBM pSeries qemu machine, is_qemu is not
set. So feature like GRUB_IEEE1275_FLAG_HAS_CURSORONOFF is not
enabled. This results in cursor not being displayed during the
grub-menu.

From ca7d011e65c6dc1b633c85b7105c807b929598f1 Mon Sep 17 00:00:00 2001

Subject: [PATCH 16/23] Add grub_dl_find_section_addr
ppc64 needs to find the address of the toc section.
Create grub_dl_find_section_addr to do this.
We also need grub_dl_find_section, so make it global.

Subject: [PATCH 21/23] fix the .toc section alignment
the .toc section in powerpc64le modules are sometimes
not aligned on a four byte boundary. This fails the module linker especially
when processing R_PPC64_TOC16_LO_DS, since the addresses are expected to be
aligned on 4byte boundary.

From c7fbe6c1ae22ac9853b03a3d4d742712f31e69b9 Mon Sep 17 00:00:00 2001
From: Ram Pai <linuxram@us.ibm.com>
Date: Tue, 25 Feb 2014 23:31:06 +0000
Subject: [PATCH 23/23] grub segfaults if initrd is specified before specifying
grub segfaults if initrd is specified before specifying
the kernel. The problem is the initrd module sees that kernel is not
specified and takes the fail path. In the fail path it checks if anything has
be malloc'ed. Unfortunately the variable that it looks to check for is a
uninitialized stack variable. The stack variable can incorrectly indicate
something is malloced, which leads the module to free some unallocated
memory. This patch fixes the problem by initializing the stack variable.
