2008-01-25[POWERPC] Set archdata.dma_data for direct DMA in cell_dma_dev_setup()Michael Ellerman
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] 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.

2008-01-18[POWERPC] mpc5200: Add generic support for simple MPC5200 based boardsMarian Balakowicz
This patch adds support for 'mpc5200-simple-platform' compatible boards which do not need a platform specific setup. Such boards are supported assuming the following: - GPIO pins are configured by the firmware, - CDM configuration (clocking) is setup correctly by firmware, - if the 'fsl,has-wdt' property is present in one of the gpt nodes, then it is safe to use such gpt to reset the board, - PCI is supported if enabled in the kernel configuration and if there is a PCI bus node defined in the device tree.

2008-01-17[POWERPC] iSeries: eliminate pci_dn bussubnoStephen Rothwell
xlate_iomm_address() really wants the ds_addr to pass to the HV, so store that value (instead of the BAR number) when we allocate the device bars. This is not a fast path, so we can look up the device_node property there instead of using the bussubno field of the pci_dn. The other user of iseries_ds_addr() was already scanning the device tree, so looking up a property will not slow it down any more.

Similar to of_find_compatible_node(), of_find_matching_node() and for_each_matching_node() allow you to iterate over the device tree looking for specific nodes, except that they take of_device_id tables instead of strings. This also moves of_match_node() from driver/of/device.c to driver/of/base.c to colocate it with the of_find_matching_node which depends on it.

2008-01-15[POWERPC] Fix boot failure on POWER6Paul Mackerras
Commit 473980a99316c0e788bca50996375a2815124ce1 added a call to clear the SLB shadow buffer before registering it. Unfortunately this means that we clear out the entries that slb_initialize has previously set in there. On POWER6, the hypervisor uses the SLB shadow buffer when doing partition switches, and that means that after the next partition switch, each non-boot CPU has no SLB entries to map the kernel text and data, which causes it to crash. This fixes it by reverting most of 473980a9 and instead clearing the 3rd entry explicitly in slb_initialize. This fixes the problem that 473980a9 was trying to solve, but without breaking POWER6.

2008-01-11[POWERPC] Fix CPU hotplug when using the SLB shadow bufferMichael Neuling
Before we register the SLB shadow buffer, we need to invalidate the entries in the buffer, otherwise we can end up stale entries from when we previously offlined the CPU. This does this invalidate as well as unregistering the buffer with PHYP before we offline the cpu. Tested and fixes crashes seen on 970MP (thanks to tonyb) and POWER5.
