Instead of SPRG0 (= special purpose register 272) use the new global symbol _PPC_INTERRUPT_DISABLE_MASK to store the interrupt disable mask. The benefit is that it is now possible to disable interrupts without further run-time initialization in boot_card(). At least on Freescale e500 cores this leads also to a faster execution since the mfmsr and mfspr instruction require four cycles to complete. The instructions to load the mask value can execute while the mfmsr is in progress.
