    Hi,
     
    I wonder if someone can help a newbie to the Real-Time Preemption
    Patch. After appling the lastest patch (-RT-2.6.12-final-V0.7.51-26) to the
    2.6.12 vanilla kernel I get the following error when compiling the
    patched kernel:
     
    arch/x86_64/kernel/mce.c: In function 'mce_read':
    arch/x86_64/kernel/mce.c:383: warning: type defaults to 'int' in
    declarationd of 'DECLARE_MUTEX'
    arch/x86_64/kernel/mce.c:383: warning: parameter names (without types)
    in function declaration
    arch/x86_64/kernel/mce.c:392:error: 'mce_read_sem' undeclared (first
    use in this function)
     
    Then the mce.o fails to get made and the make stops.
     
    I've tried compiling the vanilla 2.6.12 kernel without the patch and
    that works fine. It is strange that the error should be in
    arch/x86_64/kernel/mce.c as this is not altered by the patch. I've also tried saying
    no to MCE support, but got the some error.
     
    I'm using RHEL 4 on a SMP system (gcc version 3.4.3).
     
    Thanks,
     
    Steve.
