2.6.24.3-rt3 failure on ARM

2.6.24.3-rt3 failure on ARM

[Juergen Beisert]

Hi,

using 2.6.24.3-rt3 for ARM gives me this error.

[...]
  CHK     include/linux/compile.h
  CC      arch/arm/kernel/process.o
arch/arm/kernel/process.c: In function 'cpu_idle':
arch/arm/kernel/process.c:175: error: implicit declaration of function 'trace_preempt_exit_idle'
arch/arm/kernel/process.c:180: error: implicit declaration of function 'trace_preempt_enter_idle'
make[2]: *** [arch/arm/kernel/process.o] Error 1
make[1]: *** [arch/arm/kernel] Error 2

I didn't find any implementation of these functions in the kernel. Do we
need them or can I remove them?

2.6.24.3-rt3 failure on ARM

[Juergen Beisert]

Hi,

using 2.6.24.3-rt3 for ARM gives me this additional error:

[...]
  CC      kernel/softirq.o
  CC      kernel/resource.o
  CC      kernel/sysctl.o
kernel/sysctl.c:356: error: 'prof_pid' undeclared here (not in a function)
make[2]: *** [kernel/sysctl.o] Error 1
make[1]: *** [kernel] Error 2

Would the patch below a correct fix?
