this file in turn includes asm/delay.h - the header guards will catch nested inclusion still seems ugly. Should we just reference loops_per_jiffy here like other arches do in theur delay.h > +#include <asm-generic/types.h> > #include <asm/param.h> /* HZ */ > > static inline void __delay(unsigned long loops) > _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
