Hi.. can any one say where is this thread_size functionality is declared in the kernel.. please help me out.
thanks for the previous answer
but can you say is this is written in directly asm or written in C only

Which thread_size ? ? ?

cd linux-2.6.32.6/
grep -nR thread_size ./*

Code:

./arch/cris/include/arch-v32/arch/hwregs/iop/asm/iop_mpu_defs_asm.h:175:#define regk_iop_mpu_rw_thread_size               0x00000004
./arch/cris/include/arch-v32/arch/hwregs/iop/iop_mpu_defs.h:187:  regk_iop_mpu_rw_thread_size              = 0x00000004,
./drivers/net/ucc_geth.c:273:				  u32 thread_size,
./drivers/net/ucc_geth.c:293:			    qe_muram_alloc(thread_size, thread_alignment);
./drivers/net/ucc_geth.c:346:				  u32 thread_size,
./drivers/net/ucc_geth.c:374:					 thread_size);

The thread size is relative to CPU architecture. For x86, it is in include/asm-x86/page_32.h.
#define THREAD_SIZE (PAGE_SIZE << THREAD_ORDER)
