Re: 2.6.31.1 BUG #include <asm/bitsperlong.h>

[Bernard Pidoux <bernard.pidoux@upmc.fr>]

I downloaded again linux-2.6.31.1.tar.bz2 and unpacked it.

ll /usr/src/linux-2.6.31.1/include/
total 128
drwxrwxr-x   3 root root  4096 2009-09-24 17:45 acpi/
lrwxrwxrwx   1 root root     7 2009-09-27 14:34 asm -> asm-x86/
drwxrwxr-x   3 root root  4096 2009-09-24 17:45 asm-generic/
drwxr-xr-x   2 root root  4096 2009-09-27 14:34 asm-x86/

and

ll /usr/src/linux-2.6.31.1/include/asm/
total 8
-rw-r--r-- 1 root root 4890 2009-09-27 14:34 asm-offsets.h

So, I think that the kernel header problem is in the linux package, not in
my system installation.

The correct fix is to include the missing bitsperlong in
the asm-x86 directory.
In other words your kernel headers are broken.

Looking at latest kernel we do export bitsperlong.h.
So see if you can find a fix for your broken kernel headers.
