[PATCH v4 00/16] powerpc: machine check and system reset fixes
Since v3, I fixed a compile error and returned the generic machine check exception handler to be NMI on 32 and 64e, as caught by Christophe's review. Also added the last patch, just found it by looking at the code, a review for 32s would be good.
