2019-09-20arch-x86: ignore non-temporal hint for movntps/movntpd SSE instsPouya Fotouhi
Making the implementation of movntps/movntpd consistent with other non-temporal instructions. We are ignoring the hint here, and implementing those instructions as cacheable instructions. This change adds a warning to let user know about this workaround. Also, this change add the address check for second part of move.

2019-09-19python: Don't try to bind a stat group to the NULL simobject.Gabe Black
That is a SimObject like object which is used when a SimObject parameter is purposefully left empty, vs. being accidentally left empty through a typo or accidental ommission. It doesn't have a getCCObject method, and attempting to use it anyway causes gem5 to crash.

2019-09-18arch-arm: Fix Data Abort ISS when caused by Atomic operationGiacomo Travaglini
Data Aborts caused by an atomic instruction have a special rule for their syndrome: From a ISS point of view they count as read if a read to that address would generate a fault; they count as writes otherwise (ISS.WnR bit) This patch is implementing this in the TLB. For permission faults we need to explicitly check if a read would trigger a fault (e.g. checking for the AP bits) since permissions can allow read-only accesses. For other MMU exceptions (like translation faults) we are confident the nature of the access doesn't affect the genration of a fault. This means that if the access is atomic, we treat it as a read from an ISS.WnR point of view.
