* cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): ia64Rusty Russell2009-01-011-0/+2
| | | | | | | | | | Impact: New API The old topology_core_siblings() and topology_thread_siblings() return a cpumask_t; these new ones return a (const) struct cpumask *. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
* cpumask: IA64: Introduce cpumask_of_{node,pcibus} to replace ↵Rusty Russell2008-12-261-1/+6
| | | | | | | | | | | | | | | | | | | {node,pcibus}_to_cpumask Impact: New APIs The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these return a pointer to a struct cpumask. Part of removing cpumasks from the stack. We can also use the new for_each_cpu_and() to avoid a temporary cpumask, and a gratuitous test in sn_topology_show.

* cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell2008-12-131-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup Each SMP arch defines these themselves. Move them to a central location. Twists: 1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a CONFIG_INIT_ALL_POSSIBLE for this rather than break them. 2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'. Those archs simply have phys_cpu_present_map replaced everywhere. 3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky so I just manipulate them both in sync. 4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map' declarations.

* [IA64] fix the difference between node_mem_map and node_start_pfnKen'ichi Ohmichi2008-11-041-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | makedumpfile[1] cannot run on ia64 discontigmem kernel, because the member node_mem_map of struct pgdat_list has invalid value. This patch fixes it. node_start_pfn shows the start pfn of each node, and node_mem_map should point 'struct page' of each node's node_start_pfn. On my machine, node0's node_start_pfn shows 0x400 and its node_mem_map points 0xa0007fffbf000000. This address is the same as vmem_map, so the node_mem_map points 'struct page' of pfn 0, even if its node_start_pfn shows 0x400. The cause is due to the round down of min_pfn in count_node_pages() and node0's node_mem_map points 'struct page' of inactive pfn (0x0).

|/ | | | | | | | | | | | | | | | | | | | | | Every call of kvm_set_irq() should offer an irq_source_id, which is allocated by kvm_request_irq_source_id(). Based on irq_source_id, we identify the irq source and implement logical OR for shared level interrupts. The allocated irq_source_id can be freed by kvm_free_irq_source_id(). Currently, we support at most sizeof(unsigned long) different irq sources.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch contains Intel IOMMU IA64 specific code. It defines new machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush function, etc. For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected, dig_vtd is used for machinve vector. Otherwise, kernel falls back to dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off" can be used to force kernel to boot dig machine vector.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to mmap legacy IO space to the legacy_io files in sysfs on platforms that support it. This will allow to clean up X to use this instead of /dev/mem for legacy IO accesses such as those performed by Int10. While at it I moved pci_create/remove_legacy_files() to pci-sysfs.c where I think they belong, thus making more things statis in there and cleaned up some spurrious prototypes in the ia64 pci.h file Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
