This can result in an empty topology directory in sysfs, and requires in-kernel users to protect all uses with #ifdef - see <http://marc.info/?l=linux-netdev&m=120639033904472&w=2>. The documentation of CPU topology specifies what the defaults should be if only partial information is available from the hardware. So we can provide these defaults as a fallback. This patch: - Adds default definitions of the 4 topology macros to <linux/topology.h> - Changes drivers/base/topology.c to use the topology macros unconditionally and to cope with definitions that aren't lvalues - Updates documentation accordingly [ From: Andrew Morton <akpm@linux-foundation.org> - fold now-duplicated code - fix layout ] Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Cc: Vegard Nossum <vegard.nossum@gmail.com> Cc: Nick Piggin <nickpiggin@yahoo.com.au> Cc: Chandra Seetharaman <sekharan@us.ibm.com> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Mike Travis <travis@sgi.com> Cc: Christoph Lameter <clameter@sgi.com> Cc: John Hawkes <hawkes@sgi.com> Cc: Zhang, Yanmin <yanmin.zhang@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> |
