Unfortunately, to get those ia64 up and running with the upstream kernel
required some significant efforts. I'd leave that for now until it is
something very important.

OK, will check with that. BTW, git.kernel.org is kind of broken for me
very often those days, as almost all my tests got this,
+ git clone http://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git -b dev
Cloning into 'ext4'...
fatal: The remote end hung up unexpectedly
fatal: recursion detected in die handler

Therefore, it is going to take a while to re-try later as the test systems
here always do testing from a clean environment, i.e., re-install OS, and
then re-clone the tree etc. :\
