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.
