Subject: SMP busted on non-cpu-hotplug systems
Date: Sat, 25 Mar 2006 02:42:26 -0800 (PST) [thread overview]
Message-ID: <20060325.024226.53296559.davem@davemloft.net> (raw)
I just noticed this on sparc64, as I lost 31 cpus on my
Niagara box due to it :)
boot_cpu_init() sets the boot processor ID in cpu_present_map.
But fixup_cpu_present_map() will only populate the cpu_present_map if
it is empty, which it won't be because of what boot_cpu_init() just
did.
