x86/oprofile: disable preemption in nmi_shutdown
fix: BUG: using smp_processor_id() in preemptible [00000000] code: oprofiled/27301 caller is nmi_shutdown+0x11/0x60 Pid: 27301, comm: oprofiled Not tainted 2.6.26-rc7 #25 [<c028a90d>] debug_smp_processor_id+0xbd/0xc0 [<c045fba1>] nmi_shutdown+0x11/0x60 [<c045dd4a>] oprofile_shutdown+0x2a/0x60 Note that we don't need this for the other functions, since they are all called with on_each_cpu() (which disables preemption for us anyway).
