This patch was dropped because it is obsolete
------------------------------------------------------
Subject: i386: use raw_smp_processor_id() in die()
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
We missed one:
BUG: using smp_processor_id() in preemptible [00000001] code: modprobe/3107
caller is die+0x5d/0x1db
Pid: 3107, comm: modprobe Not tainted 2.6.24-rc5-mm1 #24
[<c0108eb2>] show_trace_log_lvl+0x12/0x25

[<f8a446c7>] acpi_video_bus_add+0x85b/0xbf4 [video]
[<c023b3cf>] acpi_device_probe+0x3e/0xdb
Convert the other debugging smp_processor_id() calls in there too - perhaps
they are also callable under conditions where preemption is thought to be
enabled.
