Subject: [Linux-ia64] [patch] logical CPU numbering
Date: Thu, 20 Mar 2003 19:03:57 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590723705277@msgid-missing> (raw)
Hello,
If a CPU fails to start during smp_boot_cpus(), then the logical CPU
numbering gets will have a "hole". Using the number of booted CPU's
instead of the loop index will correct this.
This patch is against 2.4.21-pre5.
thanks,
mh
