actual kernel not compiling

[Heiko S. <hei...@in...>]

Hello,

I get the newest kernel from
git clone git://newgolddream.dyndns.info/

because I hoped to get rid of my problems, when I activate the cache
on my SH7750R based board.

When I compiled it without Cache (CONFIG_CACHE_OFF activated):
I get the following error:

  UPD     include/linux/compile.h
  CC      init/version.o

make: *** [.tmp_vmlinux1] Fehler 1

with CONFIG_CACHE_WRITETHROUGH=y I get

  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
arch/sh/kernel/built-in.o:(__ksymtab+0xd0): undefined reference to

making the following changes:

and it compiles clean (with CONFIG_CACHE_WRITETHROUGH=y)...
but I am not sure if this is correct.

I use gcc:

Nevertheless, with caches activated, Linux doesnt boot ... I am 
searching for this ...
