Subject: [PATCH] 2.5.29 fix for undef num_possible_cpus
Date: Sat, 27 Jul 2002 23:16:40 -0400 [thread overview]
Message-ID: <3D436218.5150A206@attbi.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 2045 bytes --]
Hello Linus,
APM changes in 2.5.29 replaced num_online_cpus with
num_possible_cpus. I cannot find num_possible_cpus
defined anywhere.
Please revert back to num_online_cpus to link successfully.
Thanks,
Albert
