For example:
guest OS user space accesses device type memory, but happen SError. because the
SError is asynchronous faults, it does not take immediately.
Hi James,
Thanks for the review. I will read your comments carefully and then reply to
you.

Hi gengdongjiu,
Can you give us a specific example of an error you are trying to handle?
How would a non-KVM user space process handle the error?
KVM-users should be regular user space processes, we should not have a KVM-way
and everyone-else-way of handling errors.

when SError happen, kvm notifies user space to record the CPER,
user space specifies and passes the contents of ESR_EL1 on taking
a virtual SError interrupt to KVM, KVM enables virtual system
error or asynchronous abort with this specifies syndrome. This
patch modify the world-switch to restore VSE
