This patch removes the need for the bit_operations.h include file which
can now be deleted.  It also contains some minor corrections to comments
(typos and alignment of ASCII formulas).  I have also removed some #if
lines that were not necessary.

I have tested the patch using a unit test module that runs in kernel
mode and have verified that the patched code gives identical results to
the previous version using a 8000 sample input sequence.  Let me know if
you want this unit test, it runs automatically when the module is
insmod-ed and outputs a go/no go result:

# insmod oslec.ko
# dmesg
[17191803.480000] oslec_test installed
[17191803.480000] Testing OSLEC with 128 taps (16 ms tail)
[17191803.496000] Oslec Unit Test PASSED! pass: 8000  fail: 0
