  "message": "[Blackfin] arch: fix bug - trap_tests fails to recover on some tests.\n\nhttp://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action\u003dTrackerItemEdit\u0026tracker_item_id\u003d3719\n\nWhen the CPLBs get a miss, we do:\n  - find a victim in the HW table\n  - remove the victim\n  - find the replacement in the software table\n  - put it into the HW table.\n\nIf we can\u0027t find a replacement in the software table, we accidently\nleave a duplicate in the HW table. This patch ensures that duplicate\nis marked as not valid.\n\nWhat we should do is find the replacement in the software table, before\nwe find a victim in the HW table - but its too late in the release cycle\nto do that much restructuring of this code.\n\nRather that duplicate code, connect Hardware Errors (irq5) into trap_c,\nso user space processes get killed properly.\n\nThe rest of irq_panic() can be moved into traps.c (later)\n\nThere is still a small corner case that causes problems when a\npheriperal interrupt goes off a single cycle before a user space\nhardware error. This causes a kernel panic, rather than the user\nspace process being killed.\n\nBut, this checkin makes things work in 99.9% of the cases, and is a vast\nimprovement from what is there today (which fails 100% of the time).\n\nSigned-off-by: Robin Getz \u003crobin.getz@analog.com\u003e\nSigned-off-by: Bryan Wu \u003cbryan.wu@analog.com\u003e\n\n",
