-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).
