[SPARC]: Simplify and correct __cpu_find_by()

2006-07-21T21:18:15Z

By using for_each_node_by_type(). Also, correct a spurioud test in check_cpu_node() on sparc64. It is only called with nodes that have device_type "cpu". Signed-off-by: David S. Miller

[SPARC64]: Move over to GENERIC_HARDIRQS.

2006-06-20T08:23:32Z

This is the long overdue conversion of sparc64 over to the generic IRQ layer. The kernel image is slightly larger, but the BSS is ~60K smaller due to the reduced size of struct ino_bucket. A lot of IRQ implementation details, including ino_bucket, were moved out of asm-sparc64/irq.h and are now private to arch/sparc64/kernel/irq.c, and most of the code in irq.c totally disappeared. One thing that's different at the moment is IRQ distribution, we do it at enable_irq() time. If the cpu mask is ALL then we round-robin using a global rotating cpu counter, else we pick the first cpu in the mask to support single cpu targetting. This is similar to what powerpc's XICS IRQ support code does. This works fine on my UP SB1000, and the SMP build goes fine and runs on that machine, but lots of testing on different setups is needed.

[SPARC64]: Kill ino_bucket->pil

2006-06-20T08:21:57Z

And reuse that struct member for virt_irq, which will be used in future changesets for the implementation of mapping between real and virtual IRQ numbers. This nicely kills off a ton of SBUS and PCI controller PIL assignment code which is no longer necessary. Signed-off-by: David S. Miller

[SPARC64]: Fix new context version SMP handling.

2006-03-20T09:14:21Z

Don't piggy back the SMP receive signal code to do the context version change handling. Instead allocate another fixed PIL number for this asynchronous cross-call. We can't use smp_call_function() because this thing is invoked with interrupts disabled and a few spinlocks held. Also, fix smp_call_function_mask() to count "cpus" correctly. There is no guarentee that the local cpu is in the mask yet that is exactly what this code was assuming. Signed-off-by: David S. Miller
