Subject: RE: [PATCH] topology.h define mess fix

> - Major cross-architecture built test is required.

Some problems on ia64.  With defconfig build (which has
CONFIG_NUMA=y) I see this:

kernel/sched.c: In function 'find_next_best_node':
kernel/sched.c:6920: error: implicit declaration of function 'node_to_cpumask_ptr'
kernel/sched.c:6920: error: '__tmp__' undeclared (first use in this function)
kernel/sched.c:6920: error: (Each undeclared identifier is reported only once
kernel/sched.c:6920: error: for each function it appears in.)
kernel/sched.c: In function 'sched_domain_node_span':
kernel/sched.c:6952: error: 'nodemask' undeclared (first use in this function)
kernel/sched.c:6953: warning: ISO C90 forbids mixed declarations and code
kernel/sched.c:6964: error: implicit declaration of function 'node_to_cpumask_ptr_next'
kernel/sched.c: In function '__build_sched_domains':
kernel/sched.c:7510: error: 'pnodemask' undeclared (first use in this function)

On an "allnoconfig" build (which curiously also has CONFIG_NUMA=y :-) I see

mm/page_alloc.c: In function 'find_next_best_node':
mm/page_alloc.c:2086: error: implicit declaration of function 'node_to_cpumask_ptr'
mm/page_alloc.c:2086: error: 'tmp' undeclared (first use in this function)
mm/page_alloc.c:2086: error: (Each undeclared identifier is reported only once
mm/page_alloc.c:2086: error: for each function it appears in.)
mm/page_alloc.c:2107: error: implicit declaration of function 'node_to_cpumask_ptr_next'

There are most probably more errors ... but this is where the build stopped.
