James Hogan 6538953f1e MIPS: mipsregs.h: Make read_c0_prid use const accessor ... Make read_c0_prid() use the new constant accessor macros so that it can potentially be optimised or removed by the compiler. This is particularly important under virtualisation, where even with hardware assisted virtualisation (VZ), access to the PRid register may need to be emulated by the hypervisor. In particular this helps eliminate the read of the PRid register in the rather frequently called add_interrupt_randomness() (which calls into arch/mips/include/asm/timex.h) when the prid is unused but the read can't be removed due to the inline asm being marked __volatile__.
