Mark Nelson 36350e0069 powerpc/pseries: Fix kexec regression caused by CPPR tracking ... The code to track the CPPR values added by commit 49bd364713 ("powerpc/pseries: Track previous CPPR values to correctly EOI interrupts") broke kexec on pseries because the kexec code in xics.c calls xics_set_cpu_priority() before the IPI has been EOI'ed. This wasn't a problem previously but it now triggers a BUG_ON in xics_set_cpu_priority() because os_cppr->index isn't 0. Fix this problem by setting the index on the CPPR stack to 0 before calling xics_set_cpu_priority() in xics_teardown_cpu(). Also make it clear that we only want to set the priority when there's just one CPPR value in the stack, and enforce it by updating the value of os_cppr->stack[0] rather than os_cppr->stack[os_cppr->index]. While we're at it change the BUG_ON to a WARN_ON.
