Verifying...

These files in linux-2.6.28.6/arch:

arm/include/asm/errno.h
avr32/include/asm/errno.h
blackfin/include/asm/errno.h
cris/include/asm/errno.h
h8300/include/asm/errno.h
ia64/include/asm/errno.h
s390/include/asm/errno.h
sh/include/asm/errno.h
x86/include/asm/errno.h

just #include asm-generic/errno.h and do nothing else.

powerpc/include/asm/errno.h does the same, and then
makes one correction:

#undef  EDEADLOCK
#define EDEADLOCK       58      /* File locking deadlock error */
#define _LAST_ERRNO     516

In strace tree:

arm - ok, has no errnoent.h
avr32 - unsupported arch?
blackfin - ok, has no errnoent.h
cris - unsupported arch?
h8300 - unsupported arch?

ia64:
# diff -u
errnoent.h ../errnoent.h                                               
--- errnoent.h  2000-02-03 23:01:30.000000000 +0100
+++ ../errnoent.h       2008-04-19 21:07:23.000000000 +0200

...
so indeed its errnoent.h has no unique info.

s390[x]: same picture as in ia64

sh:
-       "ERRNO_125", /* 125 */
-       "ERRNO_126", /* 126 */
-       "ERRNO_127", /* 127 */
-       "ERRNO_128", /* 128 */
-       "ERRNO_129", /* 129 */
-       "ERRNO_130", /* 130 */
-       "ERRNO_131", /* 131 */
+       "ECANCELED", /* 125 */

+       "EKEYREJECTED", /* 129 */
+       "EOWNERDEAD", /* 130 */
+       "ENOTRECOVERABLE", /* 131 */
thus it's ok

sh64 - ok, has no errnoent.h
x86 - ok, has no errnoent.h


Your patch removes

 linux/ia64/errnoent.h
 linux/s390/errnoent.h
 linux/s390x/errnoent.h
 linux/sh/errnoent.h

so it looks 100% correct.

I am applying the patch, and then will try to deal with powerpc
by adding single #if.

Thanks!
