Merge Blackfin-uClinux tree with latest Linus GIT tree including "LOG2.H" patch failed

[Bryan Wu]

Dear David and Forks:

I am a developer of Blackfin uClinux (blackfin.uclinux.org). After git clone
the latest Linus GIT tree and quilt the blackfin-uclinux patch list, I met
some problems related with your log2.h patches when I try to compile the
kernel. The compile log is listed as below:
