Subject: MIPS: remove local_irq_[save|restore] from CP0 macros
X-Git-Tag: v2019.01-rc3~19^2~11

MIPS: remove local_irq_[save|restore] from CP0 macros

With moving write_on_tlb() to arch/mips/include/asm/mipsregs.h
there are now compiler warnings when some generic code includes
asm/io.h. This happens for example when enabling OF live tree.
