Hi
I had the same problem with
* Kernel 3.4.2
* Patch 3.4.2 rt 10
* make for a mpc8xx custom board
As far as I remember I added an #include to <asm/bug.h> in
include/linux/spinlock.h and it worked
Regards
Christophe

Hi all!
We have detected a compilation error in the following scenario:
1. kernel linux-3.4.3
2. patch-3.4.3-rt11.patch
3. make mpc85xx_defconfig
4. Select full preemption.
After make you get:
$ make
scripts/kconfig/conf --silentoldconfig Kconfig
#
# configuration written to .config
#
CHK include/linux/version.h

function 'BUG_ON' [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
A quick and dirt solution is to add the line:
#include <asm/bug.h>
just before the definition of the function:
static inline void assert_spin_locked(spinlock_t *lock)
in the file: include/linux/spinlock_rt.h
I assume that there is a missing include somewhere in the include
path, but I cannot find it so far. I hope this information helps.

Iratxo.
