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 :-)

It's used in reversing the bits in a byte value as well, which your
patch breaks (see the bitrev8 users)

Well you can do that modifying the value of k. I commented these in the
program.
