Kumar Gala	4b98d9e713	powerpc/book3e-64: Add helper function to setup IVORs ... Not all 64-bit Book-3E parts will have fixed IVORs so add a function that cpusetup code can call to setup the base IVORs (0..15) to match the fixed offsets. We need to 'or' part of interrupt_base_book3e into the IVORs since on parts that have them the IVPR doesn't extend as far down.

Kumar Gala	6c188829d2	powerpc/book3e-64: Wait til generic_calibrate_decr to enable decrementer ... Match what we do on 32-bit Book-E processors and enable the decrementer in generic_calibrate_decr. We need to make sure we disable the decrementer early in boot since we currently use lazy (soft) interrupt on 64-bit Book-E and possible get a decrementer exception before we are ready for it.

Benjamin Herrenschmidt	2d27cfd328	powerpc: Remaining 64-bit Book3E support ... This contains all the bits that didn't fit in previous patches :-) This includes the actual exception handlers assembly, the changes to the kernel entry, other misc bits and wiring it all up in Kconfig.
