Subject: [Qemu-devel] [PULL v3 03/22] cpu: Reorder cpu->as, cpu->thread_id, cpu->memory_dispatch init
Date: Thu, 9 Jul 2015 15:23:53 +0200 [thread overview]
Message-ID: <1436448252-1916-4-git-send-email-afaerber@suse.de> (raw)
In-Reply-To: <1436448252-1916-1-git-send-email-afaerber@suse.de>
From: Eduardo Habkost <ehabkost@redhat.com>
Instead of initializing cpu->as, cpu->thread_id, and reloading memory
map while holding cpu_list_lock(), do it earlier, before locking the CPU
list and initializing cpu_index.
This allows the code handling cpu_index and global CPU list to be
isolated from the rest.
