powerpc/irq: Remove IRQF_DISABLED

2011-11-08T03:51:46Z

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by: Yong Zhang Acked-by: Arnd Bergmann Acked-by: Geoff Levand Signed-off-by: Benjamin Herrenschmidt

powerpc/85xx: issue 15 EOI after core reset for FSL CoreNet devices

2011-11-03T18:12:27Z

This is listed as a requirement for Freescale CoreNet based devices (e.g p4080ds with MPIC v4.x) after issuing a core reset to properly clear pending interrupts. Signed-off-by: Matthew McClintock Signed-off-by: Kumar Gala

powerpc/mpic: Add support for discontiguous cores

2011-09-19T23:19:42Z

There is one place in the MPIC driver that assumes that the cores are numbered from 0 to n-1. However, this is not true if the CPUs are not numbered sequentially. This can happen on a eight-core SOC where cores two and three are removed in the device tree. So instead of blindly looping, we iterate over the discovered CPUs and use the SMP ID as the index. This means that we no longer ask the MPIC how many CPUs there are, so we also delete mpic->num_cpus. We also catch if the number of CPUs in the SOC exceeds the number that the MPIC supports. This should never happen, of course, but it's good to be sure. Signed-off-by: Timur Tabi Signed-off-by: Benjamin Herrenschmidt

arch/powerpc: use printk_ratelimited instead of printk_ratelimit

2011-06-29T05:31:01Z

Since printk_ratelimit() shouldn't be used anymore (see comment in include/linux/printk.h), replace it with printk_ratelimited. Signed-off-by: Christian Dietrich Signed-off-by: Benjamin Herrenschmidt

powerpc: make irq_choose_cpu() available to all PIC drivers

2011-06-23T02:44:59Z

Move irq_choose_cpu() into arch/powerpc/kernel/irq.c so that it can be used by other PIC drivers. The function is not MPIC-specific. Signed-off-by: Stuart Yoder Signed-off-by: Timur Tabi Signed-off-by: Kumar Gala

powerpc/mpic: Support compiling with DEBUG enabled

2011-06-20T01:21:44Z

Support compilation of mpic.c with DEBUG defined, as now we have irq_desc and not irq number. Signed-off-by: Dmitry Eremin-Solenikov Signed-off-by: Benjamin Herrenschmidt

powerpc/mpic: add the mpic global timer support

2011-05-19T06:14:28Z

Add support for MPIC timers as requestable interrupt sources. Based on http://patchwork.ozlabs.org/patch/20941/ by Dave Liu. Signed-off-by: Dave Liu Signed-off-by: Scott Wood Signed-off-by: Kumar Gala
