benh,
FWIW this is fixing a regression from:
4474ef0 powerpc: Rework set_dabr so it can take a DABRX value as well

Benh,
Can you take this for 3.10 also?

Some CPUs have a DABR but not DABRX. Configuration are:
- No 32bit CPUs have DABRX but some have DABR.
- POWER4+ and below have the DABR but no DABRX.
- 970 and POWER5 and above have DABR and DABRX.
- POWER8 has DAWR, hence no DABRX.
This introduces CPU_FTR_DABRX and sets it on appropriate CPUs.
