One inline comment and nit, but then I'm ok with this. Should elaborate about why we're doing this in the commit message.

Comment at: lib/Target/PowerPC/PPCFrameLowering.cpp:1217
       int Offset = MFI.getObjectOffset(CSI[I].getFrameIdx());
+      if (movingStackUpdateDown) {
+        Offset -= NegFrameSize;
No braces here. Also comment.
