2010-05-17KVM: PPC: Make Alignment interrupts work againAlexander Graf
In the process of merging Book3S_32 and 64 I somehow ended up having the alignment interrupt handler take last_inst, but the fetching code not fetching it. So we ended up with stale last_inst values. Let's just enable last_inst fetching for alignment interrupts too. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-05-17KVM: PPC: Add generic segment switching codeAlexander Graf
This is the code that will later be used instead of book3s_64_slb.S. It does the last step of guest entry and the first generic steps of guest exiting, once we have determined the interrupt is a KVM interrupt. It also reads the last used instruction from the guest virtual address space if necessary, to speed up that path. The new thing about this file is that it makes use of generic long load and store functions and calls a macro to fill in the actual segment switching code. That still needs to be done differently for book3s_32 and book3s_64. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
