2008-01-25[POWERPC] Revert chrp_pci_fixup_vt8231_ata devinit to fix libata on pegasosOlaf Hering
Commit 6d98bda79bea0e1be26c0767d0e9923ad3b72f2e 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.

2008-01-25[POWERPC] Use archdata.dma_data in dma_direct_ops and add the offsetMichael Ellerman
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.

2008-01-25[POWERPC] Add celleb_dma_dev_setup()Michael Ellerman
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.

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.

2008-01-25[POWERPC] Always hookup PHB IO resource even when emptyBenjamin Herrenschmidt
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.

2008-01-25[POWERPC] PS3: Use the HVs storage device notification mechanism properlyGeert Uytterhoeven
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.

2008-01-25[POWERPC] kdump shutdown hook supportMichael Neuling
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.

2008-01-25[POWERPC] Make smp_send_stop() handle panic and xmon rebootOlof Johansson
smp_send_stop() will send an IPI to all other cpus to shut them down. However, for the case of xmon-based reboots (as well as potentially some panics), the other cpus are (or might be) spinning with interrupts off, and won't take the IPI. Current code will drop us into the debugger when the IPI fails, which means we're in an infinite loop that we can't get out of without an external reset of some sort. Instead, make the smp_send_stop() IPI call path just print the warning about being unable to send IPIs, but make it return so the rest of the shutdown sequence can continue. It's not perfect, but the lesser of two evils. Also move the call_lock handling outside of smp_call_function_map so we can avoid deadlocks in smp_send_stop().
