Hi,
when linking the kernel I get the following error:

make: *** [vmlinux] Error 1
I had no problems compiling 2.4.17. Then I applied patch 2.4.18-rc1 without
error, and the above problem appeared. Then I applied the incremental
patches through -rc4 but the problem remains.
I have all tools in the right versions and did the usual make dep; make
clean; make -j5 bzImage. Any idea? config attached.
Thanks,

2.4.18-rc1 unexports page_cache_release and replaces it with a macro, so you
may have one driver under the fs directory that now needs to include
linux/pagemap.h.
You'll catch the culprit with simething like :
# find fs -name '*.o' | xargs nm -oa|grep page_cache_release
But I sincerely think that you have a damaged 2.4.17 source tree. You may want
to de-tar it again to check. I tried to compile everything under 2.4.18-rc1,
and all compiled well. You may have tried rmap or other patches on it before.
Well, finally I compiled 2.4.18-rc4 with your .config (gcc-2.95.3) while typing
this mail and it compiled and linked :
