<pre>commit 78071c2fa53db2f04b8eddc6e6118be4fbc5c2fe (HEAD, upstream/master)

igt/gem_tiled_partial_pwrite_pread: Check for known swizzling
As we want to compare a templated tiling pattern against the target_bo,
we need to know that the swizzling is compatible. Or else the two
tiling pattern may differ due to underlying page address that we cannot
know, and so the test may sporadically fail.
