2008-12-19sched: convert BALANCE_FOR_xx_POWER to inline functionsVaidyanathan Srinivasan
Impact: cleanup BALANCE_FOR_MC_POWER and similar macros defined in sched.h are not constants and have various condition checks and significant amount of code that is not suitable to be contain in a macro. Also there could be side effects on the expressions passed to some of them like test_sd_parent(). This patch converts all complex macros related to power savings balance to inline functions.

2008-12-18x86: use possible_cpus=NUM to extend the possible cpus allowedMike Travis
Impact: add new boot parameter Use possible_cpus=NUM kernel parameter to extend the number of possible cpus. The ability to HOTPLUG ON cpus that are "possible" but not "present" is dealt with in a later patch. Signed-off-by: Mike Travis <travis@sgi.com>
2008-12-18x86: fix cpu_mask_to_apicid_and to include cpu_online_maskMike Travis
Impact: fix potential APIC crash In determining the destination apicid, there are usually three cpumasks that are considered: the incoming cpumask arg, cfg->domain and the cpu_online_mask. Since we are just introducing the cpu_mask_to_apicid_and function, make sure it includes the cpu_online_mask in it's evaluation. [Added with this patch.] There are two io_apic.c functions that did not previously use the cpu_online_mask: setup_IO_APIC_irq and msi_compose_msg. Both of these simply used cpu_mask_to_apicid(cfg->domain & TARGET_CPUS), and all but one arch (NUMAQ[*]) returns only online cpus in the TARGET_CPUS mask, so the behavior is identical for all cases. [*: NUMAQ bug?] Note that alloc_cpumask_var is only used for the 32-bit cases where it's highly likely that the cpumask set size will be small and therefore CPUMASK_OFFSTACK=n. But if that's not the case, failing the allocate will cause the same return value as the default. Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-18Merge branch 'x86/apic' into cpus4096Ingo Molnar
This done for conflict prevention: we merge it into the cpus4096 tree because upcoming cpumask changes will touch apic.c that would collide with x86/apic otherwise.

2008-12-17USB: skip Set-Interface(0) if already in altsetting 0Alan Stern
When a driver unbinds from an interface, usbcore always sends a Set-Interface request to reinstall altsetting 0. Unforunately, quite a few devices have buggy firmware that crashes when it receives this request. To avoid such problems, this patch (as1180) arranges to send the Set-Interface request only when the interface is not already in altsetting 0.

2008-12-16x86: Update io_apic.c to use new cpumask APIMike Travis
Impact: cleanup, consolidate patches, use new API Consolidate the following into a single patch to adapt to new sparseirq code in arch/x86/kernel/io_apic.c, add allocation of cpumask_var_t's in domain and old_domain, and reduce further merge conflicts. Only one file (arch/x86/kernel/io_apic.c) is changed in all of these patches. 0006-x86-io_apic-change-irq_cfg-domain-old_domain-to.patch 0007-x86-io_apic-set_desc_affinity.patch 0008-x86-io_apic-send_cleanup_vector.patch 0009-x86-io_apic-eliminate-remaining-cpumask_ts-from-st.patch 0021-x86-final-cleanups-in-io_apic-to-use-new-cpumask-AP.patch Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
2008-12-16x86: update add-cpu_mask_to_apicid_and to use struct cpumask*Mike Travis
Impact: use updated APIs Various API updates for x86:add-cpu_mask_to_apicid_and (Note: separate because previous patch has been "backported" to 2.6.27.) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
2008-12-16x86: Add cpu_mask_to_apicid_andMike Travis
Impact: new API Add a helper function that takes two cpumask's, and's them and then returns the apicid of the result. This removes a need in io_apic.c that uses a temporary cpumask to hold (mask & cfg->domain). Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
