+From c7fb93ec51d462ec3540a729ba446663c26a0505 Mon Sep 17 00:00:00 2001
+From: Michael Brown <mbrown@fensystems.co.uk>
+Date: Thu, 10 Jul 2014 12:26:20 +0100
+Subject: x86/efi: Include a .bss section within the PE/COFF headers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The PE/COFF headers currently describe only the initialised-data
+portions of the image, and result in no space being allocated for the
+uninitialised-data portions. Consequently, the EFI boot stub will end
+up overwriting unexpected areas of memory, with unpredictable results.
+
+Fix by including a .bss section in the PE/COFF headers (functionally
+equivalent to the init_size field in the bzImage header).
