I have problems pulling linux kernel changes from 33ac02aa4cef417871e128ab4a6565e751e5f3b2 to b0825488a642cadcf39709961dde61440cb0731c into my local tree. At first I thought your patch would fix it, but it doesn't:

r3000:~/git$ cat linux/.git/HEAD
b0825488a642cadcf39709961dde61440cb0731c
r3000:~/git$ git-clone-script -l linux linux.test
