From 4ed940d4c34c21a1a356969a923f2815d608e0bf Mon Sep 17 00:00:00 2001 From: Yasuaki Ishimatsu Date: Mon, 30 Jul 2012 14:41:13 -0700 Subject: firmware_map: make firmware_map_add_early() argument consistent with firmware_map_add_hotplug() There are two ways to create /sys/firmware/memmap/X sysfs: - firmware_map_add_early When the system starts, it is calledd from e820_reserve_resources() - firmware_map_add_hotplug When the memory is hot plugged, it is called from add_memory() But these functions are called without unifying value of end argument as below: - end argument of firmware_map_add_early() : start + size - 1 - end argument of firmware_map_add_hogplug() : start + size The patch unifies them to "start + size". Even if applying the patch, /sys/firmware/memmap/X/end file content does not change.
