cpumask: use new cpumask functions throughout x86

2009-03-13T04:19:54Z

Impact: cleanup 1) &cpu_online_map -> cpu_online_mask 2) first_cpu/next_cpu_nr -> cpumask_first/cpumask_next 3) cpu_*_map manipulation -> init_cpu_* / set_cpu_* Signed-off-by: Rusty Russell

cpumask: convert struct cpuinfo_x86's llc_shared_map to cpumask_var_t

2009-03-13T04:19:53Z

Impact: reduce kernel memory usage when CONFIG_CPUMASK_OFFSTACK=y Signed-off-by: Rusty Russell

cpumask: convert node_to_cpumask_map[] to cpumask_var_t

2009-03-13T04:19:53Z

Impact: reduce kernel memory usage when CONFIG_CPUMASK_OFFSTACK=y Straightforward conversion: done for 32 and 64 bit kernels. node_to_cpumask_map is now a cpumask_var_t array. 64-bit used to be a dynamic cpumask_t array, and 32-bit used to be a static cpumask_t array. Signed-off-by: Rusty Russell

x86: unify 32 and 64-bit node_to_cpumask_map

2009-03-13T04:19:52Z

Impact: cleanup We take the 64-bit code and use it on 32-bit as well. The new file is called mm/numa.c. In a minor cleanup, we use cpu_none_mask instead of declaring a local cpu_mask_none. Signed-off-by: Rusty Russell

cpumask: x86: convert cpu_sibling_map/cpu_core_map to cpumask_var_t

2009-03-13T04:19:50Z

Impact: reduce per-cpu size for CONFIG_CPUMASK_OFFSTACK=y In most places it's cleaner to use the accessors cpu_sibling_mask() and cpu_core_mask() wrappers which already exist. I couldn't avoid cleaning up the access in oprofile, either. Signed-off-by: Rusty Russell

cpumask: remove cpu_coregroup_map: x86

2009-03-13T04:19:48Z

Impact: cleanup cpu_coregroup_mask is the New Hotness. Signed-off-by: Rusty Russell

x86: remove smp_apply_quirks()/smp_checks()

2009-03-08T15:22:56Z

Impact: cleanup and code size reduction on 64-bit This code is only applied to Intel Pentium and AMD K7 32-bit cpus. Move those checks to intel_init()/amd_init() for 32-bit so 64-bit will not build this code. Also change to use cpu_index check to see if we need to emit warning.

x86: apic: simplify secondary CPU wakeup methods

2009-02-26T12:58:26Z

Impact: cleanup - rename apic->wakeup_cpu to apic->wakeup_secondary_cpu, to make it apparent that this is an SMP-only method - handle NULL ->wakeup_secondary_cpus to mean the default INIT wakeup sequence - this allows simplification of the APIC driver templates.

x86: remove update_apic from x86_quirks

2009-02-26T05:32:25Z

Impact: cleanup x86_quirks->update_apic() calling looks crazy. so try to remove it: 1. every apic take wakeup_cpu member directly 2. separate es7000_apic to es7000_apic_cluster 3. use uv_wakeup_cpu directly Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86, apic: remove ->store_NMI_vector()

2009-02-17T16:53:56Z

Impact: cleanup It's not used by anything anymore. Signed-off-by: Ingo Molnar
