* [PATCH] use struct irq_chip instead of struct hw_interrupt_typeAneesh Kumar K.V2006-10-112-2/+2

* [PATCH] mm: use symbolic names instead of indices for zone initialisationMel Gorman2006-10-119-27/+36
| | | | | | | | | | | | | | | | | | | | | | | Arch-independent zone-sizing is using indices instead of symbolic names to offset within an array related to zones (max_zone_pfns). The unintended impact is that ZONE_DMA and ZONE_NORMAL is initialised on powerpc instead of ZONE_DMA and ZONE_HIGHMEM when CONFIG_HIGHMEM is set. As a result, the the machine fails to boot but will boot with CONFIG_HIGHMEM turned off. The following patch properly initialises the max_zone_pfns[] array and uses symbolic names instead of indices in each architecture using arch-independent zone-sizing. Two users have successfully booted their powerpcs with it (one an ibook G4). It has also been boot tested on x86, x86_64, ppc64 and ia64. Please merge for 2.6.19-rc2. Credit to Benjamin Herrenschmidt for identifying the bug and rolling the first fix. Additional credit to Johannes Berg and Andreas Schwab for reporting the problem and testing on powerpc.

| * [POWERPC] Fix secondary CPU startup on old "powersurge" SMP powermacsPaul Mackerras2006-10-101-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the old "powersurge" SMP powermacs, the second CPU is started up by sending it an IPI, which has the side effect of stopping the timebase clock (so the secondary CPU's timebase can be synchronized with the primary's). The routine that did this used udelay, which will hang forever when the timebase is stopped, since udelay now spins until the timebase reaches a certain value. The end result is that the kernel would hang when bringing up the second CPU. This fixes it by using a simple loop which just does a fixed number of iterations to generate the delay. These old systems were all clocked at around 200 MHz or so, so a fixed number of iterations is acceptable. Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [POWERPC] Fix Maple secondary IDE interruptBenjamin Herrenschmidt2006-10-101-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | The IDE driver will pick up the PCI IRQ for both channels on Maple despite the fact that it's in legacy mode. This works around it by "hiding" the PCI IRQ of the AMD8111 IDE controller when it's configured in legacy mode on the Maple platform, thus causing the driver to call pci_get_legacy_ide_irq() which will return the correct interrupts for both channels.

* [PATCH] x86_64 irq: Scream but don't die if we receive an unexpected irqEric W. Biederman2006-10-091-7/+7
| | | | | | | | | | | | | | | | | | | | | | | Due to code bugs or misbehaving hardware it is possible that we can receive an interrupt that we have not mapped into a linux irq. Calling BUG when that happens is very rude, and if the problem is mild enough prevents anything else from getting done. So instead of calling BUG just scream loudly about the problem and continue running. We don't have enough knowledge to know which interrupt triggered this behavior so we don't acknowledge it. This will likely prevent a recurrence of the problem by jamming up the works with an unacknowledged interrupt. If the interrupt was something important it is quite possible that nothing productive will happen past this point. But it is now at least possible to keep working if the kernel can survive without the interrupt we dropped on the floor. Solutions like irqpoll should generally make dropped irqs non-fatal.
