Subject: percpu data for non-existant cpus
Date: Tue, 04 Nov 2003 00:55:24 +0000 [thread overview]
Message-ID: <marc-linux-ia64-106790736528585@msgid-missing> (raw)
It was neccessary in 2.4 to allocate cpu_data areas for
non-existent cpus. I forget where, but some generic
initialization code expected to be able to reference cpu_data
for all cpus up to NR_CPUS.
Does 2.6 have the same requirement or can I allocate cpu_data
areas only for cpus that exist or might exist (cpu_possible()).
