Fixed both now, thanks for the report.
I had to add a user_addr_max() definition here, which unfortunately
will also conflict
with the get_fs() removal if Christoph plans to have that merged
through the microblaze
tree.
If this becomes a problem, I could merge both series through the
asm-generic tree.
