Hello Avi,
while fixing a module reference counting problem for s390 I spotted
another problem in the kvm main code. Any comments on the patch?
From: Christian Borntraeger <[EMAIL PROTECTED]>
There is a race between a "close of the file descriptors" and module
unload in the kvm module.

Hi,
When using a kvm.git kernel as host, I am getting guest boot failures
when booting Fedora Rawhide kernel (2.6.27.5-117.fc10.x86_64). Guest

guest would see an interrupt at a higher priority than it has programmed
the hardware to allow.
I consider this a bit far fetch.

It should be an old issue we didn't sense before. To specify single object's compile option, only CFLAGS can work in this case.
