I realize the EFI stub for ARM patches are in flight, https://lkml.org/lkml/2013/8/9/554 and overlap with some of the files but I wanted to send these out for comment. This series fixes a problem with EFI memory maps larger than 128 entries when booting using the EFI boot stub, which results in overflowing the e820_map in boot_params and an eventual halt when checking the map size in sanitize_e820_map(). The fix implemented is to add the EFI memory map from setup_arch() via a memory_setup hook. Two options were considered: 1. Use the SETUP_E820_EXT setup_data type to add the extra entries. 2. Create a memory_setup function to be enabled when the EFI memory map is needed. Option 2 appeared to be the cleaner solution, reducing duplication with existing code, given a reasonable mechanism for determining when to replace the default memory_setup function.
