2007-12-24[Blackfin] arch: Fix gpio label handlingMichael Hennerich6-13/+28
early serial init also utilizes the peripheral request api - however at this point bfin_gpio_init didn't allocate memory for the labels. So we always have two zombies (allocated pin functions without labels) This happens before the initcalls - We now allocate memory statically. Define MAX_RESOURCES individually for each cpu.

2008-01-27[Blackfin] arch: fix bug - trap_tests fails to recover on some tests.Robin Getz5-71/+99
http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3719 When the CPLBs get a miss, we do: - find a victim in the HW table - remove the victim - find the replacement in the software table - put it into the HW table. If we can't find a replacement in the software table, we accidently leave a duplicate in the HW table. This patch ensures that duplicate is marked as not valid. What we should do is find the replacement in the software table, before we find a victim in the HW table - but its too late in the release cycle to do that much restructuring of this code. Rather that duplicate code, connect Hardware Errors (irq5) into trap_c, so user space processes get killed properly. The rest of irq_panic() can be moved into traps.c (later) There is still a small corner case that causes problems when a pheriperal interrupt goes off a single cycle before a user space hardware error. This causes a kernel panic, rather than the user space process being killed. But, this checkin makes things work in 99.9% of the cases, and is a vast improvement from what is there today (which fails 100% of the time).
