2.4.20 compilation failure

[Taras Ciuriak <tnmc@soliton.com>]

Hi all...

I downloaded 2.4.20 from kernel.org and tried compiling it (my install 
defaulted to 2.2.20).  I had a problem initially with some variables not 
getting set but found that was a result of my having done "make xconfig" 
which is ackowledged broken on the aurora-devel list archives on the 
web.  "make menuconfig" fixed that.

However, I now have another problem and I can't find any reference to 
this after much googling;

mm/mm.o: In function `kmap_high':
mm/mm.o(.text+0x11b18): undefined reference to `pkmap_base'
mm/mm.o(.text+0x11b7c): undefined reference to `pkmap_base'
mm/mm.o(.text+0x11bd4): undefined reference to `pkmap_base'
mm/mm.o(.text+0x11c10): undefined reference to `pkmap_base'
mm/mm.o: In function `kunmap_high':
mm/mm.o(.text+0x11c6c): undefined reference to `pkmap_base'
mm/mm.o(.text+0x11c8c): more undefined references to `pkmap_base' follow
make: *** [vmlinux] Error 1

Further;

Of which "arch/sparc/mm/srmmu.c:unsigned long pkmap_base;" seems to be 
the relevant line, though I'm no expert in these matters.

This is an SS5...anyone know anything about this?  Cheers.../Taras
