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:

PS3: Add repository polling loop to work around timing bug On some firmware versions (e.g. 1.90), the storage device may not show up in the repository immediately after receiving the notification message. Add a small polling loop to make sure we don't miss it. 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.

This makes the setjmp/longjmp code used by xmon, generically available to other code. It also removes the requirement for debugger hooks to be only called on 0x300 (data storage) exception. Signed-off-by:

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(). Signed-off-by:

smp_call_function_map should be static, and for consistency prepend it with __ like other local helper functions in the same file. Signed-off-by:
