Subject: Compile bug in 2.6.24.8-rt7 on ARM

Hello Steven,

Now I started looking at compiling 2.6.24.7-rt8 for ARM, and I found
another compile problem... ;-))

This one:
 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'

These function do not appear to exist _anywhere_ in the kernel.
So these calls can safely be removed, I guess.

The offending patch can be found in the broken-out set under the name
arm-trace-preempt-idle.patch.
Attached you can find a fix for it (I expect that you will not need it)

Kind Regards,

Remy
