Hi Ralf,
I understand that that I need to make kmalloc.h in my arch specific
folder. But I could not get answer, what should be appropriate
value of ARCH_KMALLOC_MINALIGN is it 32 or 128 ?
You've been replied already that you should set it to 32.
Thanks.

I will give more info.
CONFIG_MIPS_L1_CACHE_SHIFT=5

mips 34kc is processor
and File we are using is arch/mips/include/asm/mach-generic/kmalloc.h
#ifndef __ASM_MACH_GENERIC_KMALLOC_H
#define __ASM_MACH_GENERIC_KMALLOC_H
#ifndef CONFIG_DMA_COHERENT

#define ARCH_KMALLOC_MINALIGN 128

#endif /* __ASM_MACH_GENERIC_KMALLOC_H */
So shall we make value ARCH_KMALLOC_MINALIGN from 128 to 32. is
there any problem ?
No, that's just what you should do. You do that by putting a file
that defines ARCH_KMALLOC_MINALIGN into your platforms's
arch/mips/include/asm/mach-<yourplatform>/kmalloc.h just like the ip32
file from your original posting.
