Compile error: 2.4.15-pre4 (-tr) in kernel.o (cpu_init()) - advice req'd

[Ben Ryan <ben@bssc.edu.au>]

hey all

hope this doesn't turn out to be spurious traffic...

ia32/uniproc

linux-2.4.14.tar (kernel tar)
patch-2.4.15-pre4 (merge)
fix-2.4.15-pre4-tr.diff (benlahaise; don't mind the filename, i just
                         reckon calling the patch for the patch,
                         patch-2.4.* is brokenness)


there is some weirdness on the box i'm compiling on; please check the
following for obvious causes...
pre-compile make's worked fine, but the compile itself crashed out
with:

arch/i386/kernel/kernel.o: In function 'cpu_init':
arch/i386/kernel/kernel.o(.text.init+0x27f9): undefined reference to 'cpucount'
arch/i386/kernel/kernel.o(.text.init+0x2831): undefined reference to 'cpucount'


Can anyone spot if it's code or meatware related??
Thanx, I won't be able to sleep till I know what's going on :)

cheers
