Sorry, I didn't test it but I have some questions.  Why do you add a 
wrapper and pollute all AcpiOsQueueForExecution()/AcpiOsExecute() 
consumers?  Isn't it more simpler to let the function determine to 
queue or not to queue?  Why do you check cold and rebooting flags?  
If you wanted to check the taskqueue is ready, you could check 
taskqueue_acpi is NULL or not, instead.

Thanks,
