Subject2.4.17 raid5 checksumming function selection wierdness
Date
The raid5 code in 2.4.17 seems to select the slowest available
checksumming function.

Part of dmesg output follows:

[...]
raid5: measuring checksumming speed
8regs : 2148.000 MB/sec
32regs : 1900.400 MB/sec
pIII_sse : 1272.000 MB/sec
pII_mmx : 3291.200 MB/sec
p5_mmx : 4212.400 MB/sec
raid5: using function: pIII_sse (1272.000 MB/sec)
[...]

The machine is an Athlon XP 1400MHz on an MSI K7T266Pro2 board with
512 Mb of PC2100 DDR.
