[PATCH] acpi memory hotplug: remove strange add_memory fail message
I wrote a patch to avoid redundant memory hot-add call at boot time. This was cause of strange fail message of memory hotplug like "ACPI: add_memory failed". Memory is recognized by early boot code with EFI/E820. But, if DSDT describes memory devices for them, then hot-add code is called for already recognized memory, and it shows fail messages with -EEXIST. So, sys admin will misunderstand this message as something wrong by it. This patch avoids them by preventing redundant hot-add call until completion of driver initialization.
