Fixing requirements for PAddrBits ( #961 )
...
Previously, the requirement for PAddrBits only checked to be equal or greater than the bundle bits. Changing it to check for these to match exactly as for cases when the PAddrBits greater than address bits we could run into scenarios which cause possible address wrap around issues.

Don't permit new acquires until the release queue is drained

If the queue is not empty before a dirty miss, C could block D.
I haven't seen this in the wild, but it could happen because of
dirty probe responses backed up in the queue.

Fix priority inversion for two back-to-back divides ( #948 )
...
If the first one is killed for some unrelated reason (e.g. write port
hazard), the second one will still issue to the div-sqrt unit. While
it will itself later be killed, the fact that the later instruction
acquires a resource needed by the former instruction leads to deadlock.

Don't examine a packet's xcpt signal if it might be invalid. In this case,
the correct fix is to not examine xcpt at all; the deleted code was vestigial.
(Note, the other use of xcpt(j+1) in this code is indeed safe.)

Don't merge stores that manifest WAW hazards
...
The following sequence would drop the first store when eccBytes=4:
sb x0, 0(t0)
nop
sb x0, 4(t0)
nop
sb x0, 1(t0)
Because the first and second store are to different ECC granules, the
hazard check correctly allowed the second one to proceed, but the third
was merged with the second, even though it conflicted with the first.
So, don't allow the third to be merged with the second, since the second
stored to a different ECC granule.
