Hi, Keir
Yes, we do some discussion about the interface compatibility problem before
submitting.
But we found the mceinj_cpunr below is defined as unsigned int (not uint32), so
we think it may have some problem in 32/64 bit machine originally.
So we gave up the backward compatibility effort and made it as uint32_5. But if
sun/oracle use this interface before, we did have some problem
So Christopher and Gavin, any suggestions for this?
Regards,
criping
I have no problems with this change. dom0/Xen should match in version
anyway. There have been ABI breakages in the dom0/Xen interface before.
You can bump the xen MCE hypercall version if you wish..
