... In the first email of the series: > By popular demand, I've redone the patchset to include volatile casts in > atomic_set as well. I've also converted the macros to inline functions, to > help catch type mismatches at compile time. and in the rest of include/asm-arm/atomic.h: #else /* ARM_ARCH_6 */ #include <asm/system.h> #ifdef CONFIG_SMP #error SMP not supported on pre-ARMv6 CPUs #endif #define atomic_set(v,i) (((v)->counter) = (i)) Seems you missed that.
