delayed allocation and multipage I/O patches for 2.5.6.

2.5.6 with Andrew's everything patch on ext2
filesystem mounted with delalloc came up with
these MB/second on k6-2/475 with IDE disk:

dbench 128
2.5.6 2.5.6-akpme akpm % faster
8.4 12.5 48

tiobench seq reads (8 - 128 threads avg 3 runs)
2.5.6 2.5.6-akpme %
9.36 12.97 38

tiobench seq writes (8 - 128 threads avg 3 runs)
2.5.6 2.5.6-akpme %
15.3 19.29 26

Both kernels needed reiserfs patches for 2.5.6, but above tests are on ext2.
