2009-01-15[IA64] Update to use account_{steal,idle}_ticksIsaku Yamahata1-2/+2
This patch fixes the following errors caused by 79741dd35713ff4f6fd0eafd59fa94e8a4ba922d which changed the prototypes of account_steal_time() and account_idle_time(). > CC arch/ia64/xen/time.o > arch/ia64/xen/time.c: In function 'consider_steal_time': > arch/ia64/xen/time.c:132: warning: passing argument 1 of 'account_steal_time' makes integer from pointer without a cast > arch/ia64/xen/time.c:132: error: too many arguments to function 'account_steal_time' > arch/ia64/xen/time.c:133: warning: passing argument 1 of 'account_steal_time' makes integer from pointer without a cast > arch/ia64/xen/time.c:133: error: too many arguments to function 'account_steal_time' Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Tony Luck <tony.luck@intel.com>
2009-01-15irq: update all arches for new irq_desc, fixMike Travis1-4/+8
Impact: fix build errors Since the SPARSE IRQS changes redefined how the kstat irqs are organized, arch's must use the new accessor function: kstat_incr_irqs_this_cpu(irq, DESC); If CONFIG_SPARSE_IRQS is set, then DESC is a pointer to the irq_desc which has a pointer to the kstat_irqs. If not, then the .irqs field of struct kernel_stat is used instead. Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

IA64 dynamic ftrace support. The original _mcount stub for each function is like: alloc r40=ar.pfs,12,8,0 mov r43=r0;; mov r42=b0 mov r41=r1 nop.i 0x0 br.call.sptk.many b0 = _mcount;; The patch convert it to below for nop: [MII] nop.m 0x0 mov r3=ip nop.i 0x0 [MLX] nop.m 0x0 nop.x 0x0;; This isn't completely nop, as there is one instuction 'mov r3=ip', but it should be light and harmless for code follow it. And below is for call [MII] nop.m 0x0 mov r3=ip nop.i 0x0 [MLX] nop.m 0x0 brl.many .;; In this way, only one instruction is changed to convert code between nop and call. This should meet dyn-ftrace's requirement. But this requires CPU support brl instruction, so dyn-ftrace isn't supported for old Itanium system. Assume there are quite few such old system running.

2009-01-07mm: show node to memory section relationship with symlinks in sysfsGary Hade1-1/+1
Show node to memory section relationship with symlinks in sysfs Add /sys/devices/system/node/nodeX/memoryY symlinks for all the memory sections located on nodeX. For example: /sys/devices/system/node/node1/memory135 -> ../../memory/memory135 indicates that memory section 135 resides on node1. Also revises documentation to cover this change as well as updating Documentation/ABI/testing/sysfs-devices-memory to include descriptions of memory hotremove files 'phys_device', 'phys_index', and 'state' that were previously not described there. In addition to it always being a good policy to provide users with the maximum possible amount of physical location information for resources that can be hot-added and/or hot-removed, the following are some (but likely not all) of the user benefits provided by this change. Immediate: - Provides information needed to determine the specific node on which a defective DIMM is located. This will reduce system downtime when the node or defective DIMM is swapped out. - Prevents unintended onlining of a memory section that was previously offlined due to a defective DIMM. This could happen during node hot-add when the user or node hot-add assist script onlines _all_ offlined sections due to user or script inability to identify the specific memory sections located on the hot-added node. The consequences of reintroducing the defective memory could be ugly. - Provides information needed to vary the amount and distribution of memory on specific nodes for testing or debugging purposes. Future: - Will provide information needed to identify the memory sections that need to be offlined prior to physical removal of a specific node. Symlink creation during boot was tested on 2-node x86_64, 2-node ppc64, and 2-node ia64 systems. Symlink creation during physical memory hot-add tested on a 2-node x86_64 system.

This patch introduces a global pointer, dma_ops, which points to an appropriate dma_mapping_ops that the kernel should use. This is a common way to handle multiple dma_mapping_ops (X86, POWER, and SPARC). dma_ops is set in platform_dma_init. We also set it by hand where machvec_init is callev via subsys_initcall. - IA64_DIG_VTD uses vtd_dma_ops. - IA64_HP_ZX1 uses sba_dma_ops. - IA64_HP_ZX1_SWIOTLB uses hwsw_dma_ops. - IA64_SGI_SN2 uses sn_dma_ops. - The rest use swiotlb_dma_ops.

2009-01-06add map/unmap_single_attr and map/unmap_sg_attr to struct dma_mapping_opsFUJITA Tomonori1-0/+14
This adds map/unmap_single_attr and map/unmap_sg_attr to struct dma_mapping_ops. This enables us to move the dma operations in struct ia64_machine_vector to struct dma_mapping_ops. Note that we will remove map/unmap_sg and map/umap_single. This is a preparation of struct dma_mapping_ops unification.

2009-01-04ia64: cpumask fix for is_affinity_mask_valid()Mike Travis2-10/+7
Impact: cleanup The function prototype should use 'struct cpumask *' to declare cpumask arguments (instead of cpumask_var_t). Note: arch/ia64/kernel/irq.c still had the following "old cpumask_t" usages: 105: cpumask_t mask = CPU_MASK_NONE; 107: cpu_set(cpu_logical_id(hwid), mask); 110: irq_desc[irq].affinity = mask; ... replaced with a simple "cpumask_of(cpu_logical_id(hwid))". 161: new_cpu = any_online_cpu(cpu_online_map); 194: time_keeper_id = first_cpu(cpu_online_map); ... replaced with cpu_online_mask refs.
