2.4.26-pre5: XFS module link errors on PPC

[Meelis Roos]

I tried to make enamble a modular XFS on my PPC using current linux-2.4
bitkeeper snaphot. Unfortunately, there are unresolved symbols in xfs
module:

depmod: *** Unresolved symbols in /lib/modules/2.4.26-pre5/kernel/fs/xfs/xfs.o
depmod:         ioremap_bot
depmod:         vmalloc_start

XFS works fine when compiled in statically.

Looks like XFS is picking them up via VMALLOC_START and VMALLOC_END
which are usually constants, but looks like these map to a couple
of global variables on PPC.  This should fix it, but I haven't got
a machine handy to test with...

cheers.
