    SubjectRe: [patch] Real-Time Preemption, -RT-2.6.11-rc3-V0.7.38-01
    I am seeing:
    kernel/built-in.o(.text+0x4974): In function `copy_mm':
    /usr/src/cvs/mvl-kernel-26/makena/linux-2.6.10/kernel/fork.c:493: undefined
    reference to `__spin_is_locked'
    kernel/built-in.o(.text+0x9f5a): In function `next_thread':
    /usr/src/cvs/mvl-kernel-26/makena/linux-2.6.10/kernel/exit.c:877: undefined
    reference to `__raw_rwlock_is_locked'
    net/built-in.o(.text+0x1258): In function `__sock_create':
    /usr/src/cvs/mvl-kernel-26/makena/linux-2.6.10/net/socket.c:175: undefined
    reference to `__spin_is_locked'
    net/built-in.o(.text+0x16b54): In function `dev_deactivate':
    /usr/src/cvs/mvl-kernel-26/makena/linux-2.6.10/net/sched/sch_generic.c:594:
    undefined reference to `__spin_is_locked'
    make[1]: *** [vmlinux] Error 1
    make: *** [bzImage] Error 2


    Possibly from:
    define __raw_spin_is_locked(x) (*(volatile signed char *)(&(x)->lock) <= 0)
    #define __raw_spin_unlock_wait(x) \
    do { barrier(); } while(__spin_is_locked(x))
    in asm/spinlock.h

    should that be __raw_spin_is_locked(x) instead?
