Hi Dave,
Today's linux-next merge of the agp tree got a conflict in
drivers/char/agp/uninorth-agp.c between commit uninorth_create_gatt_table
("agp/uninorth: Simplify cache flushing") from the powerpc tree and
commit 6a12235c7d2d75c7d94b9afcaaecd422ff845ce0 ("agp: kill phys_to_gart
() and gart_to_phys()") from the agp tree.
Just context changes. I fixed it up (see below) and can carry the fix as
necessary.
