Hi Doug and Jason,
Here are two patches that should probably land in the RC. The first one ensures we don't index beyond the end of an array. The other is more subtle but arguably more important. The bug it fixes results in incorrect IRQ bits to be set and the result is we do not get an interrupt for an error and have to wait for another interrupt to fire to see said error.
Dennis Dalessandro (1): IB/hfi1: Ensure ucast_dlid access doesnt exceed bounds
Michael J. Ruhl (1): IB/hfi1: set_intr_bits uses incorrect source for register modification
These don't apply to current for-rc:

Ah, I think I got my wires crossed. Mike's patch should land in for-next. It fixes one of his earlier patches that Doug pulled in. Can you just apply this there or do you want me to re-send? My patch can still go to -rc though.
