Hello, i forget to mention that i have some dirty hack in build process.
In compilation, there is error message.
/data/maribaya/kernel_src/include/asm/processor.h:80: error:
`CONFIG_X86_L1_CACHE_SHIFT' undeclared here (not in a function)
/data/maribaya/kernel_src/include/asm/processor.h:80: error: requested
alignment is not a constant
In file included from /data/maribaya/kernel_src/include/linux/list.h:8,
from /data/maribaya/kernel_src/include/linux/lockdep.h:12,

/data/maribaya/kernel_src/include/linux/spinlock_types.h:12,

from /data/maribaya/kernel_src/include/linux/gfp.h:4,
from /data/maribaya/kernel_src/include/linux/slab.h:14,
It seems strange for me , because kernel build is successfull & my PC
running with this kernel. I build my kernel from clean kernel.
So, in makefile i add :
CFLAGS += -DCONFIG_X86_L1_CACHE_SHIFT=7
Thx
