Hey guys...

i m trying to compile an android kernel 2.6.35 to be deployed on my board...i keep havingthis compilation error and i want to know what is the problem

CHK include/linux/version.h
CHK include/generated/utsrelease.h
make[1]: « include/generated/mach-types.h » est à jour.
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
GEN .version
CHK include/generated/compile.h
UPD include/generated/compile.h
CC init/version.o
LD init/built-in.o
LD .tmp_vmlinux1
drivers/built-in.o: In function `pmem_cache_maint':
tcb_clksrc.c.text+0x27c44): undefined reference to `clean_and_invalidate_caches'
tcb_clksrc.c.text+0x27c5c): undefined reference to `clean_caches'
tcb_clksrc.c.text+0x27c74): undefined reference to `invalidate_caches'
make: *** [.tmp_vmlinux1] Erreur 1


PS: the compilation environnement is set correctly ARCH CROSS_COMPILE ... the config as well...and the file pmem.c includes the one having the above references declared...and the tcb_clksrc.c has none of the undefined references above...for more info please don't hesitate

Thanks in Advance
