>= 2.6.20-rt8 ppc compile error

["Pradyumna Sampath" <pradyumna.sampath@gmail.com>]

Hi everyone,

I am trying to get the linux >= 2.6.20-rt8 (+ Tsutomu's patches) to
2.6.21-rt11 for the lite5200b compiled and have been getting a bunch
of compile time errors. Please let me know if I am doing something
wrong here.

thanks in advance
regards
prady
