The common arch/powerpc code calls in to functions in setup-bus.c so some builds of ppc32 would fail. Note, ppc32 usage of setup-irq.c is limited to arch/ppc and should be removed when arch/ppc goes away. Signed-off-by:

This reverts commit 5c3f5892, basically because it changes behaviour even when no fake NUMA information is specified on the kernel command line. Firstly, it changes the nid, thus destroying the real NUMA information. Secondly, it also changes behaviour in that if a node ends up with no memory in it because of the memory limit, we used to set it online and now we don't. Also, in the non-NUMA case with no fake NUMA information, we do node_set_online once for each LMB now, whereas previously we only did it once. I don't know if that is actually a problem, but it does seem unnecessary. Signed-off-by:

This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc. Signed-off-by:

Commit 6d98bda7 changed the init order for chrp_pci_fixup_vt8231_ata(). It can not work anymore because either the irq is not yet set to 14 or pci_get_device() returns nothing. At least the printk() in chrp_pci_fixup_vt8231_ata() does not trigger anymore. pata_via works again on Pegasos with the change below. Signed-off-by:

Michael Ellerman authored
Now that all platforms using dma_direct_offset setup the archdata.dma_data correctly, we can change the dma_direct_ops to retrieve the offset from the dma_data, rather than directly from the global. While we're here, change the way the offset is used - instead of or'ing it into the value, add it. This should have no effect on current implementations where the offset is far larger than memory, however in future we may want to use smaller offsets. Signed-off-by:

Celleb always uses dma_direct_ops, and sets dma_direct_offset, so it too should set dma_data to dma_direct_offset. Currently there's no pci_dma_dev_setup() routine for Celleb so add one. Signed-off-by:

Store the direct_dma_offset in each device's dma_data in the case where we're using the direct DMA ops. We need to make sure we setup the ppc_md.pci_dma_dev_setup() callback if we're using a non-zero offset. Signed-off-by:

We must always hookup the pci_bus resource 0 to the PHB io_resource even if the latter is empty (the bus has no IO support). Otherwise, some other code will end up hooking it up to something bogus and the resource tree will end up being broken. This fixes boot on QS20 Cell blades where the IDE driver failed to allocate the IO resources due to breakage of the resource tree. Signed-off-by:

The PS3 hypervisor has a storage device notification mechanism to wait until a storage device is ready. Unfortunately the storage device probing code used this mechanism in an incorrect way, needing a polling loop and handling of devices that are not yet ready. This change corrects this by: - First waiting for the reception of an asynchronous notification that a new storage device became ready, - Then looking up the storage device in the device repository. On shutdown, the storage probe thread is stopped and the storage notification device is closed using a reboot notifier. Signed-off-by: -

This adds hooks into the default_machine_crash_shutdown so drivers can register a function to be run in the first kernel before we hand off to the second kernel. This should only be used in exceptional circumstances, like where the device can't be reset in the second kernel alone (as is the case with eHEA). To emphasize this, the number of handles allowed to be registered is currently #def to 1. This uses the setjmp/longjmp code around the call out to the registered hooks, so any bogus exceptions we encounter will hopefully be recoverable. Tested with bogus data and instruction exceptions.
