[PATCH 17/27] Make head_64.S aware of KVM real mode code

2009-10-30 Thread Alexander Graf
We need to run some KVM trampoline code in real mode. Unfortunately, real mode only covers 8MB on Cell so we need to squeeze ourselves as low as possible. Also, we need to trap interrupts to get us back from guest state to host state without telling Linux about it. This patch adds interrupt traps
