X-Git-Tag: v3.12-rc1~184^2~92 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=29f1953d51faa3995192ba4ccff3b71c661940c2;p=pandora-kernel.git cpu topology: remove stale arch_provides_topology_pointers and define_siblings_show_map/list() arch_provides_topology_pointers was introduced in commit 23ca4bba3 (x86: cleanup early per cpu variables/accesses v4) to indicate pointers to the topology cpumask_t maps are valid to avoid copying data on to/off of the stack. But later in commit fbd59a8d (cpumask: Use topology_core_cpumask()/ topology_thread_cpumask()), the pointers to the topology struct cpumask maps are always valid. After that commit, the only difference is that there is a redundant "unsigned int cpu = dev->id;" if arch_provides_topology_pointers defined, but dev->id is type 'u32' which devolves to 'unsigned int' on all supported arches. So this arch_provides_topology_pointers define is pointless and only cause obfuscation now, remove it. Tested on x86 machine, topology information in sys/devices/system/cpu/ cpuX/topology/ is the same after appling this patch set.
