dmesg info with kernel from Jesse's tree on the async branch

I tested with the kernel built from the async branch. You can check the dmesg
info in the attachment.
The results of HSW eDP responsiveness is as follows:
         Initcall time:   324 msecs 
         Suspend time:  290 msecs  
         Resume time:  548 msecs

Then I set i915.fastboot=1 on the kernel command line and retested.
The result is:
         Initcall time:   324 msecs 
         Suspend time:  283 msecs  
         Resume time:  549 msecs
