The above sizes were: final code (with all patches applied)
built for i386
versus same code with #if BITS_PER_LONG >= 64 replaced by #if 1,
and a few fixes for "integer is too big for long" warnings)

For 64-bit, replacing that #if is a no-op, sizes
will be the same.

If you are asking about 64-bit size comparison *across patches*
5..8, here they are:

64-bit:
dec      hex   filename
22786    5902  2.6.23.1.camellia4.t64/crypto/camellia.o
21422    53ae  2.6.23.1.camellia5.t64/crypto/camellia.o
16355    3fe3  2.6.23.1.camellia6.t64/crypto/camellia.o
15813    3dc5  2.6.23.1.camellia7.t64/crypto/camellia.o
15670    3d36  2.6.23.1.camellia8.t64/crypto/camellia.o
