Resizing the file system can result in an in-memory inode being remapped
to a different aggregate group (AG). A cached AG number can cause
problems when trying to free or allocate inodes. Instead, save the IAG's
agstart address and calculate the agno when we need it.
Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>
A comment indicates that the IAG's agstart does not need to be updated
since it will always point to a block in the same aggregate group, but
jfs_fsck isn't so forgiving and reports it as an error.
I'm fixing this in jfsutils as well, so either a new kernel or new
utilities will be sufficient to fix the problem.

Since we were calling the wptr function before checking if the IH was

the GPU readback 0xffffffff. This reorders things so we return early

Signed-off-by: Dave Airlie <airlied@redhat.com>
Certain revisions of the vbios on DCE3.2 cards have a bug
in the transmitter control table which prevents duallink from
being enabled properly on some cards. The action switch statement
jumps to the wrong offset for the OUTPUT_ENABLE action. The fix
is to use the ENABLE action rather than the OUTPUT_ENABLE action
on the affected cards. In fixed version of the vbios, both
actions jump to the same offset, so the change should be safe.
