Note - you also need to check what the behaviour is with a pointer type too - that's the one that gets ARM if you try this. My test set on ARM was:
int test_8(unsigned char *v, unsigned char *p) { return get_user(*v, p); }
int test_16(unsigned short *v, unsigned short *p) { return get_user(*v, p); }
int test_32(unsigned int *v, unsigned int *p) { return get_user(*v, p); }
int test_32_constp(unsigned int *v, const unsigned int *p) { return get_user(*v, p); }
int test_64(unsigned long long *v, unsigned long long *p) { return get_user(*v, p); }
int test_64_narrow(unsigned long *v, unsigned long long *p) { return get_user(*v, p); }
int test_ptr(unsigned int **v, unsigned int **p) { return get_user(*v, p); }
int test_wrong(char **v, const char **p) { return get_user(*v, p); }
All but the last should build cleanly and correctly. The last should issue a warning. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
