Sorry, it looks like I have a few typos in my description.  Here's a new one:

"The do_bootm_linux() function was using the same variable ('len') to calculate 
the dtu length and the initrd length.  This meant that the initrd length was 
incorrect when it came time to book the kernel.  This resulted in the inability 
to boot with an initrd on an OF-based kernel.  This patch renames the local 
variables 'len' and 'data' to 'initrd_len' and 'initrd_data', respectively, and 
it uses initrd_len and initrd_data only for initrd calculations.

In addition, there were a few places where 'len' and 'data' where being used as 
temporary variables.  The code was modified to eliminate the need for temporary 
variables."

Does this explain everything?  Do you want me to resubmit the patch with the new 
changelog text?
