Subject: arm: KVM: Add HYP async abort handler
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cc325cfc37b5b9e8814d7172e3a6e47d3b098ff1;p=linux-beck.git

arm: KVM: Add HYP async abort handler

If we've exited the guest because it has triggered an asynchronous
abort, a possible course of action is to let it know it screwed up
by giving it a Virtual Abort to chew on.
