I saw it on sandbox platform. Does this depend on 32 bit or 64 bit system?
I found this for __kernel_size_t:
arch/sandbox/include/asm/posix_types.h:18:typedef unsigned long __kernel_size_t;
so we need to change this to:
typedef unsigned int __kernel_size_t;
but in mips arch there is unsigned long, too.

drivers/mtd/core.c: In function 'mtd_write':
drivers/mtd/core.c:82:2: warning: format '%08lx' expects type 'long unsigned int', but argument 5 has type 'size_t'
drivers/mtd/core.c:102:4: warning: format '%08lx' expects type 'long unsigned int', but argument 5 has type 'size_t'
drivers/mtd/core.c:102:4: warning: format '%08lx' expects type 'long unsigned int', but argument 6 has type 'size_t'
They go away when reverting this. It seems that different achitectures
have different ideas about size_t:
./include/linux/types.h:54:typedef __kernel_size_t size_t;
./arch/ppc/include/asm/posix_types.h:17:typedef unsigned int __kernel_size_t;
./arch/blackfin/include/asm/posix_types.h:45:typedef unsigned int __kernel_size_t;
./arch/mips/include/asm/posix_types.h:34:typedef unsigned int __kernel_size_t;
./arch/mips/include/asm/posix_types.h:39:typedef unsigned long __kernel_size_t;
./arch/x86/include/asm/posix_types.h:34:typedef unsigned int __kernel_size_t;
./arch/sandbox/include/asm/posix_types.h:18:typedef unsigned long __kernel_size_t;
./arch/nios2/include/asm/posix_types.h:30:typedef unsigned int __kernel_size_t;
./arch/openrisc/include/asm/posix_types.h:28:typedef unsigned int __kernel_size_t;
./arch/arm/include/asm/posix_types.h:30:typedef unsigned int __kernel_size_t;
On which arch did you see the warnings with the original code?

Jan
