The function add_memory_regions() is currently only called on system initialization to allocate a fixed amount of pages. As such, it didn't need to return any errors: in case it failed, we cannot proceed anyway. This will change with the upcoming support for requesting more memory from the firmware at runtime, where it doesn't make sense anymore to fail hard. Refactor the function to return an error to prepare for this. Note that this does not change the behaviour when initializing the memory system because grub_efi_mm_init() knows to call grub_fatal() in case grub_efi_mm_add_regions() returns an error.

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'
