Fix initialization of CMCI/CMCP interrupts

2013-04-02T16:37:06Z

Back 2010 during a revamp of the irq code some initializations were moved from ia64_mca_init() to ia64_mca_late_init() in commit c75f2aa13f5b268aba369b5dc566088b5194377c Cannot use register_percpu_irq() from ia64_mca_init() But this was hideously wrong. First of all these initializations are now down far too late. Specifically after all the other cpus have been brought up and initialized their own CMC vectors from smp_callin(). Also ia64_mca_late_init() may be called from any cpu so the line: ia64_mca_cmc_vector_setup(); /* Setup vector on BSP */ is generally not executed on the BSP, and so the CMC vector isn't setup at all on that processor. Make use of the arch_early_irq_init() hook to get this code executed at just the right moment: not too early, not too late.

[IA64] remove obsolete irq_desc_t typedef

2009-06-15T21:34:31Z

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have been kept around for migration reasons. After more than two years it's time to remove them finally. This patch cleans up one of the remaining users. When all such patches hit mainline we can remove the defines and typedefs finally. Impact: cleanup Convert the last remaining users and remove the typedef. Signed-off-by: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Tony Luck
