KVM: PPC: E500: exit to user space on "ehpriv 1" instruction
"ehpriv 1" instruction is used for setting software breakpoints by user space. This patch adds support to exit to user space with "run->debug" have relevant information. As this is the first point we are using run->debug, also defined the run->debug structure. Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
