You should probably #include <asm/cpuinfo.h> here since struct cpuinfo is used in the definition. > +#define TLBMISC_WAY_MASK 0xf > +#define TLBMISC_WAY_SHIFT 20 > + > +#define TLBMISC_PID (TLBMISC_PID_MASK << TLBMISC_PID_SHIFT) /* TLB PID */ > +#define TLBMISC_WE (1 << 18) /* TLB write enable */ > +#define TLBMISC_RD (1 << 19) /* TLB read */ > +#define TLBMISC_WAY (TLBMISC_WAY_MASK << TLBMISC_WAY_SHIFT) /* TLB way */ > + > +#endif /* _ASM_NIOS2_REGISTERS_H */ > -- > 1.8.3.2 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-arch" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
