Subject: [PATCH] NUMA-Q relocate early ioremap
Date: Mon, 05 Aug 2002 16:48:06 -0700 [thread overview]
Message-ID: <348510000.1028591286@flay> (raw)
This moves the early ioremap call to after cpu_online_map is initialized.
Note everything is wrapped in clustered_apic_mode, so should be safe.
Tested on NUMA-Q and std 2-way SMP through LTP.
Please apply,
Martin.
