[RFC] [PATCH] powerpc: Add MSR_DE to MSR_KERNEL

[Joakim Tjernlund]

Emulators such as BDI2000 and CodeWarrior needs to have MSR_DE set
in order to support break points.
This adds MSR_DE for kernel space only.
---

I have tested this briefly with BDI2000 on P2010(e500) and
it works for me. I don't know if there are any bad side effects, therfore
this RFC.
