| * [IA64]: SN fix bus->sysdata pointer and memory cleanupsPrarit Bhargava2005-08-161-8/+10
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Here's the patch again to fix the code to handle if the values between MAX_USER_RT_PRIO and MAX_RT_PRIO are different. Without this patch, an SMP system will crash if the values are different.

* [IA64] fix call of smp_processor_id() by XPC whileDean Nelson2005-07-131-4/+4
| | | | | | | | | | | 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 Lameter2005-07-124-7/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig and the sn2_defconfig config files. The issue with this file was the missing usage of __IA64_UL_CONST wrapper. This wrapper is defined in include/asm-ia64/types.h and wraps a long constant definition with UL or with nothing depending on its usage in the kernel.

The "hook" is to set the pm_power_off callback to ia64_sn_power_down(). pm_power_off is checked in machine_power_off()/do_poweroff() and, if set, is executed. ia64_sn_power_down() is a function already present (but not used currently) in the sn kernel. ia64_sn_power_down() makes a SAL call to execute the power off.
