Andrea Righi 4f6e6b9f97 [CPUFREQ] Fix BUG: using smp_processor_id() in preemptible code ... Use get_cpu()/put_cpu() in cpufreq_ondemand init routine, instead of smp_processor_id() to avoid the following BUG: [ 35.313118] BUG: using smp_processor_id() in preemptible [00000000] code=: modprobe/4952 [ 35.313132] caller is cpufreq_gov_dbs_init+0xa/0x8f [cpufreq_ondemand] [ 35.313140] Pid: 4952, comm: modprobe Not tainted 2.6.27-rc5-mm1 #23 [ 35.313145] Call Trace: [ 35.313158] [<ffffffff80361ff7>] debug_smp_processor_id+0xd7/0xe0 [ 35.313167] [<ffffffffa010800a>] cpufreq_gov_dbs_init+0xa/0x8f [cpufreq_ondemand] [ 35.313176] [<ffffffff8020903b>] _stext+0x3b/0x160 [ 35.313185] [<ffffffff804768c5>] __mutex_unlock_slowpath+0xe5/0x190 [ 35.313195] [<ffffffff8026236a>] trace_hardirqs_on_caller+0xca/0x140 [ 35.313205] [<ffffffff8026ef4c>] sys_init_module+0xdc/0x210 [ 35.313212] [<ffffffff8020b7cb>] system_call_fastpath+0x16/0x1b Signed-off-by: Andrea Righi <righi.andrea@gmail.com> Signed-off-by: Dave Jones <davej@redhat.com>		2008-10-09 13:52:44 -04:00
