Subject: significance of using 2kb long byte_rev_table in lib/bitrev.c

Hi,
 	i cant understand the significance of using 2kb size of
bit_rev_table array in lib/bitrev.c
I guess it has something to do with bit reversal of a 32 bit word.
Well it can be done smoothly without using such a long sized array.
I am sending patches regarding this in the following mails.
Please review them.
Thanks :-)
