Paul Mackerras 18aa0da33e powerpc: Don't try to set LPCR unless we're in hypervisor mode ... Commit 8f619b5429 ("powerpc/ppc64: Do not turn AIL (reloc-on interrupts) too early") added code to set the AIL bit in the LPCR without checking whether the kernel is running in hypervisor mode. The result is that when the kernel is running as a guest (i.e., under PowerKVM or PowerVM), the processor takes a privileged instruction interrupt at that point, causing a panic. The visible result is that the kernel hangs after printing "returning from prom_init". This fixes it by checking for hypervisor mode being available before setting LPCR. If we are not in hypervisor mode, we enable relocation-on interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.
