Subject: [PATCH 09/10] ppc64: Convert cpu_sibling_map to a per_cpu data array (v3)
Date: Tue, 11 Sep 2007 18:56:53 -0700 [thread overview]
Message-ID: <20070912015647.486500682@sgi.com> (raw)
In-Reply-To: 20070912015644.927677070@sgi.com
Convert cpu_sibling_map to a per_cpu cpumask_t array for the ppc64
architecture. This fixes build errors in block/blktrace.c and
kernel/sched.c when CONFIG_SCHED_SMT is defined.
Note: these changes have not been built nor tested.
