linux-next: manual merge of the agp tree with the powerpc tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
