From: Don Hiatt don.hiatt@intel.com

[ Upstream commit d0a2f454713a42447ee4007582c0e43c47bcf230 ]

The trace logic prior to the fixes below used to mask the A bit from the psn. It now mistakenly displays the A bit, which is already displayed separately.

Fix by adding the appropriate mask to the psn tracing.
