When initializing the EFI memory subsystem, we will by default request a quarter of the available memory, bounded by a minimum/maximum value. Given that we're about to extend the EFI memory system to dynamically request additional pages from the firmware as required, this scaling of requested memory based on available memory will not make a lot of sense anymore. Remove this logic as a preparatory patch such that we'll instead defer to the runtime memory allocator. Note that ideally, we'd want to change this after dynamic requesting of pages has been implemented for the EFI platform. But because we'll need to split up initialization of the memory subsystem and the request of pages from the firmware, we'd have to duplicate quite some logic at first only to remove it afterwards again. This seems quite pointless, so we instead have patches slightly out of order.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. 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'
