Add KVM_SET_EXIT_MSRS ioctl to allow userspace to pass in a list of MSRs that force an exit to userspace when rdmsr or wrmsr are used by the guest. KVM_SET_EXIT_MSRS will need to be called before any vCPUs are created to protect the 'user_exit_msrs' list from being mutated while vCPUs are running. Add KVM_CAP_SET_MSR_EXITS to identify the feature exists. Signed-off-by: Aaron Lewis <aaronlewis@xxxxxxxxxx> Reviewed-by: Oliver Upton <oupton@xxxxxxxxxx>
