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).
