 For the record the LMO tree <git://git.linux-mips.org/pub/scm/ralf/linux> 
has a full history recorded and is in sync with kernel.org.  There's some 
GIT magic that cuts some operations like `git log' at 2.6.12-rc2, but you 
can go beyond that if you know the right commit id, e.g.:

$ git log -p 66f0a432 -- arch/sh

I can see the initial SH import was with 2.3.19.
