I'm sorry for my slow response ... Wu Fengguang wrote: +static void sync_global_pgds(unsigned long start, unsigned long end) It seems that this function can reuse code with vmalloc_sync_all(). agreed. __init_extra_mapping() is not related to memory hotplug (note: the __init prefix), so not ... 19 May 2010 08:14

We should either test that at least one of the user events is set (see the untested patch below) or remove the test completely if we consider O... 19 May 2010 08:14
