James Hogan cd1e0737ef MIPS: mipsregs.h: Add read const Cop0 macros ... Some Cop0 registers are constant and have no side effects when read. There is no need for the inline asm to read these to be marked __volatile__, and doing so prevents them from being removed by the compiler. Add a few new accessor macros to handle these registers more efficiently (especially for the sake of running in a guest where redundant access to the register may trap to the hypervisor): __read_const_32bit_c0_register() __read_const_64bit_c0_register() __read_const_ulong_c0_register() Signed-off-by: James Hogan <jhogan@kernel.org> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Maciej W.
