* x86, apic: Fix false positive section mismatch in numaq_32.cRakib Mullick2009-07-13
| | | | | | | | | | | | | | | | | The variable apic_numaq placed in noninit section references the function wakeup_secondary_cpu_via_nmi(), which is in __cpuinit section. Thus causes a section mismatch warning. To avoid such mismatch we mark apic_numaq as __refdata. We were warned by the following warning: WARNING: arch/x86/kernel/built-in.o(.data+0x932c): Section mismatch in reference from the variable apic_numaq to the function .cpuinit.text:wakeup_secondary_cpu_via_nmi() Signed-off-by: Rakib Mullick <rakib.mullick@gmail.com> LKML-Reference: <b9df5fa10907120407p6b4f67dtf4d563155488188a@mail.gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* cpumask: remove x86 cpumask_t uses.Rusty Russell2009-03-13
| | | | | | | | | | | | | Impact: cleanup We are removing cpumask_t in favour of struct cpumask: mainly as a marker of what code is now CONFIG_CPUMASK_OFFSTACK-safe. The only non-trivial change here is vector_allocation_domain(): explicitly clear the mask and set the first word, rather than using assignment. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* cpumask: remove cpumask_t assignment from vector_allocation_domain()Rusty Russell2009-03-13
| | | | | | | | | | | | Impact: cleanup It's not legal to do assignments into cpumask_var_t; they will soon be of variable length. So explicitly clear the mask and set the first word, rather than using assignment. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* cpumask: remove dangerous CPU_MASK_ALL_PTR, &CPU_MASK_ALL.: x86Rusty Russell2009-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup (Thanks to Al Viro for reminding me of this, via Ingo) CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so: #define CPU_MASK_ALL (cpumask_t) { { ... } } Taking the address of such a temporary is questionable at best, unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added CPU_MASK_ALL_PTR: #define CPU_MASK_ALL_PTR (&CPU_MASK_ALL) Which formalizes this practice. One day gcc could bite us over this usage (though we seem to have gotten away with it so far). So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR with the modern "cpu_all_mask" (a real const struct cpumask *), and remove CPU_MASK_ALL_PTR altogether.

| | | | | | | | | | Remove __cpuinitdata section placement for translation_table structure, since it is referenced from a functions within .text.

* x86: apic: simplify secondary CPU wakeup methodsIngo Molnar2009-02-26
| | | | | | | | | | | | | | 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_quirksYinghai Lu2009-02-26
| | | | | | | | | | | | | 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 <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: move remaining APIC drivers to arch/x86/kernel/apic/*Ingo Molnar2009-02-17
Move the 32-bit extended-arch APIC drivers to arch/x86/kernel/apic/ too, and rename apic_64.c to probe_64.c. Signed-off-by: Ingo Molnar <mingo@elte.hu>
