I receive the following errors on compile, after make has gotten through
building all config options:

-- SNIP --

GEN .version
CHK include/linux/compile.h
UPD include/linux/compile.h
CC init/version.o
LD init/built-in.o
LD .tmp_vmlinux1
arch/i386/kernel/built-in.o(.text+0x398e): In function `do_nmi':
: undefined reference to `__trace'

arch/i386/mm/built-in.o(.text+0x71b): In function `do_page_fault':
: undefined reference to `__trace'
make: *** [.tmp_vmlinux1] Error 1

-P2 and -P3 gave me the same errors except for
`smp_apic_timer_interrupt'.
I have tried my .config, default, allyes, and allno, and I get the same
result regardless of config. Tree is fresh, patch applied with -Np1
<../[patchname]. I also get fuzz and offsets, but they don't seem to
bear on the problem directly. I'm currently running -P1, which doesn't
have this problem. gcc is 3.3.4.

With thanks for a smoother system feel,
