Hi, The [vk][cmz]alloc(_node) family of functions return void pointers which it's completely unnecessary/pointless to cast to other pointer types since that happens implicitly. This patch removes such casts from arch/powerpc/ Signed-off-by: NJesper Juhl <jj@chaosbits.net> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

Tie the polling mechanism into the ibm,suspend-me rtas call to stop/restart polling before/after a suspend, hibernate, migrate, or checkpoint restart operation. This ensures that the system has a chance to disable the polling if the partition is migrated to a system that does not support VPHN (and vice versa).

This patch sets a timer during boot that will periodically poll the associativity change counters in the VPA. When a change in associativity is detected, it retrieves the new associativity domain information via the H_HOME_NODE_ASSOCIATIVITY hcall and updates the NUMA node maps and sysfs entries accordingly. Note that since the ibm,associativity device tree property does not exist on configurations with both NUMA and SPLPAR enabled, no device tree updates are necessary.

The vmalloc code can track the physical address of a vma, when the vma is used for ioremap, if set it is displayed in /proc/vmallocinfo. Because get_vm_area_caller() doesn't know it's being called for ioremap() it's up to the arch code to set the phys_addr. A bunch of other arch's do this, I'm not sure why powerpc doesn't?

iommu_table_setparms_lpar needs either the phb or the subbusnumber (not both), pass the phb to make it similar to iommu_table_setparms. Note: In cases where a caller was passing bus->number previously to iommu_table_setparms_lpar() rather than phb->bus->number, this can lead to a different value in tbl->it_busno. The only example of this was the removed pci_dma_dev_setup_pSeriesLP(), removed in "ppc/iommu: remove unneeded pci_dma_dev_setup_pSeriesLP". [BenH: You updated only one of the two callers.

The block in pci_dma_dev_setup_pSeriesLP for dma_window == NULL can be removed because we will only teminate the loop if we had already allocated a iommu table for that node or we found a window. While there may be no window for the device, the intresting part is if we are reusing a table or creating it for the first device under it.

The iommu_table pointer in the pci auxiliary struct of device_node has not been used by the iommu ops since the dma refactor of 12d04eef, however this code still uses it to find tables for dlpar. By only setting the PCI_DN iommu_table pointer on nodes with dma window properties, we will be able to quickly find the node for later checks, and can remove the table without looking for the the dma window property on dlpar remove.

The IOMMU code has been passing the dma-mask instead of the coherent_dma_mask to the iommu allocator. Coherent allocations should be made using the coherent_dma_mask. Also update the vio code to ensure the coherent_dma_mask is set. Without this change drivers, such as ibmvscsi, fail to load with the corrected dma_iommu_alloc_coherent().

The nvram log partition stuff currently in nvram_64.c is really pseries specific. It isn't actually used on anything else (despite the fact that we ran the code to setup the partition on anything except powermac) and the log format is specific to pseries RTAS implementation. So move it where it belongs Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

Existing code is nasty, has bugs etc... rewrite the function more simply, and make it take the signature and optional name of the partitions to remove as arguments, thus making it a more generic utility. We also try to remove a log partition that we find and is too small rather than creating a duplicate. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

This error log stuff is really pseries specific. As a first step we move the initialization of these variables to the caller of nvram_create_partition(), which is also slightly reorganized so we setup the free partition before we clear the new partition, so the chance of an error during clear leaving us with invalid headers is lessened.
