| * [IA64-SGI] fix bte_copy() calling smp_processor_id() while preemptibleRuss Anderson2005-08-26
| | | | | | | | | | | | | | | | | | | | bte_copy() calls calls smp_processor_id(), which will get flagged if preemption if enabled. raw_smp_processor_id() is used instead because we are just using it to pick a BTE interface and are not tied to a specific cpu.

| * | [IA64]: SN fix bus->sysdata pointer and memory cleanupsPrarit Bhargava2005-08-16
| |/ | | | | | | | | | | | | | | | | | | | | The main issue is that bus_fixup calls may potentially call functions that require a valid bus->sysdata pointer. Since this is the case, we must set the bus->sysdata pointer before calling the bus_fixup functions. The remaining changes are simple fixes to make sure memory is cleaned up in the function.

* [IA64] fix call of smp_processor_id() by XPC whileDean Nelson2005-07-13
| | | | | | | | | | | XPC calls smp_processor_id() twice from xpc_setup_infrastructure() with preemption enabled, which gets flagged if 'DEBUG_PREEMPT=y'. This patch replaces the two calls to smp_processor_id() by a single call to raw_smp_processor_id() since any CPU within the partition will do.

* [IA64] Altix pcibus_to_node implementationChristoph Lameter2005-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Altix subarch does not provide node information via ACPI. Instead hooks are used to fixup pci structures. This patch determines the nodes for Altix PCI busses. Remote Bridges: --------------- Altix supports remote I/O nodes without memory or processors but with bridges. The TIOCA type of bridge is an AGP bridge and the PROM provides information about the closest node. That information will be returned by pcibus_to_node. The TIOCP remote bridge type is a PCI bridge but the PROM does not provide a closest node id. pcibus_to_node will return -1 for devices on those bridges meaning that device control structures may be allocated on any node. Safeguard: ---------- Should the fixups result in invalid node information for a pci controller then a warning will be printed and pcibus_to_node will return -1. This patch also fixes the "FIXME" in sn_dma_alloc_coherent. This means that dma_alloc_coherent will now use alloc_pages_node to allocate memory local to the node that the PCI device is connected to.
