On s390x-linux-gcc, __SIZE_TYPE__ expands to "long unsigned int" for both
32-bit s390 and 64-bit s390x, as
gcc-4.6.3-nolibc/s390x-linux/lib/gcc/s390x-linux/4.6.3/plugin/include/config/s390/linux.h
has

    #define SIZE_TYPE (TARGET_64BIT ? "long unsigned int" : "long unsigned int")

To match this, __kernel_size_t is always set to "long unsigned int".

But while __kernel_ssize_t is "long" on 64-bit s390x, it is "int" on 32-bit
s390, causing compiler warnings like:

    fs/quota/quota_tree.c:372:4: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat]

To fix this, __kernel_ssize_t should be "long", irrespective of word size.
