X86_64 compile error (crash.c)

X86_64 compile error (crash.c)

[Dieter Stüken]

I found this on 2.6.15-rc7 but it was on linux-2.6.14 already:

   CC      arch/x86_64/kernel/crash.o
In file included from include/asm/kexec.h:5,
                  from include/linux/kexec.h:9,
                  from arch/x86_64/kernel/crash.c:15:
include/asm/proto.h:66: error: syntax error before "cpu_initialized"
include/asm/proto.h:66: warning: type defaults to `int' in declaration of `cpu_initialized'
include/asm/proto.h:66: warning: data definition has no type or storage class
gmake[1]: *** [arch/x86_64/kernel/crash.o] error 1


#include <linux/cpumask.h> might be included in "asm-x86_64/proto.h"

however, it happens only with a very unusual configuration:

CONFIG_X86_64=y
CONFIG_KEXEC=y
CONFIG_COMPAT=n

else linux/cpumask.h gets included somewhere else...

Thanks for the report. I think the right fix is to move the declaration
of cpu_initialized into smp.h. I did this in my tree for 2.6.16.
