Currently when loading GRUB modules we allocate space for all sections including those without SHF_ALLOC set. We then copy the sections that /do/ have SHF_ALLOC set into the allocated memory leaving some of our allocation untouched forever. Additionally, on platforms with GOT fixups and trampolines we currently compute alignment round-ups for the sections and sections with sh_size = 0. This patch removes the extra space from the allocation computation and makes the allocation computation loop skip empty sections as the loading loop does.

See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. See the file MAINTAINERS for information about the GRUB maintainers, etc. If you found a security vulnerability in the GRUB please check the SECURITY file to get more information how to properly report this kind of bugs to the maintainers. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
