I did following:
1. To start with linux-2.6.19-rc2-orig and linux-2.6.19-rc2 are identical 2. cd linux-2.6.19-rc2; make allmodconfig; make 3. diff -uprN -X linux-2.6.19-rc2-orig/Documentation/dontdiff linux-2.6.19-rc2-orig linux-2.6.19-rc2 > /tmp/patch
The above generates 2MB patch file. What is wrong ?
It seems a new folder is created: linux-2.6.19-rc2/usr/include
diff -uprN -X linux-2.6.19-rc2-orig/Documentation/dontdiff linux-2.6.19-rc2-orig/usr/include/asm-generic/atomic.h linux-2.6.19-rc2/usr/include/asm-generic/atomic.h --- linux-2.6.19-rc2-orig/usr/include/asm-generic/atomic.h 1970-01-01 05:30:00.000000000 +0530 +++ linux-2.6.19-rc2/usr/include/asm-generic/atomic.h 2006-10-18 14:18:47.000000000 +0530 @@ -0,0 +1,117 @@ +#ifndef _ASM_GENERIC_ATOMIC_H +#define _ASM_GENERIC_ATOMIC_H +/* + * Copyright (C) 2005 Silicon Graphics, Inc. + * Christoph Lameter <clameter@sgi.com> + * + * Allows to provide arch independent atomic definitions without the need to + * edit all arch specific atomic.h files. + */ + +#include <asm/types.h> + +/* + * Suppport for atomic_long_t + * + * Casts for parameters are avoided for existing atomic functions in order to + * avoid issues with cast-as-lval under gcc 4.x and other limitations that the + * macros of a platform may have. + */ + +#if BITS_PER_LONG == 64 + +typedef atomic64_t atomic_long_t; + +#define ATOMIC_LONG_INIT(i) ATOMIC64_INIT(i) + +static __inline__ long atomic_long_read(atomic_long_t *l) +{ + atomic64_t *v = (atomic64_t *)l; + + return (long)atomic64_read(v); +} + +static __inline__ void atomic_long_set(atomic_long_t *l, long i) +{ + atomic64_t *v = (atomic64_t *)l; + + atomic64_set(v, i); +} + +static __inline__ void atomic_long_inc(atomic_long_t *l) +{ + atomic64_t *v = (atomic64_t *)l; + + atomic64_inc(v); +} + +static __inline__ void atomic_long_dec(atomic_long_t *l) +{ + atomic64_t *v = (atomic64_t *)l; + + atomic64_dec(v); +} + +static __inline__ void atomic_long_add(long i, atomic_long_t *l) +{ + atomic64_t *v = (atomic64_t *)l; + + atomic64_add(i, v); +} + +static __inline__ void atomic_long_sub(long i, atomic_long_t *l) +{ + atomic64_t *v = (atomic64_t *)l; + + atomic64_sub(i, v); +} + +#else + +typedef atomic_t atomic_long_t; + +#define ATOMIC_LONG_INIT(i) ATOMIC_INIT(i) +static __inline__ long atomic_long_read(atomic_long_t *l) +{ + atomic_t *v = (atomic_t *)l; + + return (long)atomic_read(v); +} + +static __inline__ void atomic_long_set(atomic_long_t *l, long i) +{ + atomic_t *v = (atomic_t *)l; + + atomic_set(v, i); +} + +static __inline__ void atomic_long_inc(atomic_long_t *l) +{ + atomic_t *v = (atomic_t *)l; + + atomic_inc(v); +} + +static __inline__ void atomic_long_dec(atomic_long_t *l) +{ + atomic_t *v = (atomic_t *)l; + + atomic_dec(v); +} + +static __inline__ void atomic_long_add(long i, atomic_long_t *l) +{ + atomic_t *v = (atomic_t *)l; + + atomic_add(i, v); +} + +static __inline__ void atomic_long_sub(long i, atomic_long_t *l) +{ + atomic_t *v = (atomic_t *)l; + + atomic_sub(i, v); +} + +#endif +#endif .......... .......... - 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/
