ia64: fix up obsolete cpu function usage.

2015-03-05T04:55:04+00:00

Thanks to spatch, then a sweep for for_each_cpu_mask => for_each_cpu. Signed-off-by: Rusty Russell Cc: Tony Luck Cc: Fenghua Yu Cc: linux-ia64@vger.kernel.org

ia64: use %*pb[l] to print bitmaps including cpumasks and nodemasks

2015-02-14T05:21:37+00:00

printk and friends can now format bitmaps using '%*pb[l]'. cpumask and nodemask also provide cpumask_pr_args() and nodemask_pr_args() respectively which can be used to generate the two printf arguments necessary to format the specified cpu/nodemask.

ia64, topology: Fix CPU hotplug callback registration

2014-03-20T12:43:40+00:00

Subsystems that want to register CPU hotplug callbacks, as well as perform initialization for the CPUs that are already online, often do it as shown below: get_online_cpus(); for_each_online_cpu(cpu) init_cpu(cpu); register_cpu_notifier(&foobar_cpu_notifier); put_online_cpus(); This is wrong, since it is prone to ABBA deadlocks involving the cpu_add_remove_lock and the cpu_hotplug.lock (when running concurrently with CPU hotplug operations). Instead, the correct and race-free way of performing the callback registration is: cpu_notifier_register_begin(); for_each_online_cpu(cpu) init_cpu(cpu); /* Note the use of the double underscored version of the API */ __register_cpu_notifier(&foobar_cpu_notifier); cpu_notifier_register_done(); Fix the topology code in ia64 by using this latter form of callback registration.

[IA64] Delete __cpuinit usage from all ia64 users

2013-06-24T22:44:27+00:00

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the ia64 uses of the __cpuinit macros.

[IA64] Resolve name space collision for cache_show()

2012-11-07T23:51:04+00:00

We have a local static function named rather generically "cache_show()". Changes in progress in the slab code want to use this same name globally - so they are adding their declaration to which then causes the compiler to choke with: arch/ia64/kernel/topology.c:278: error: conflicting types for 'cache_show' Fix by adding an "ia64_" prefix to our local function.

arch/ia64: remove references to cpu_*_map

2012-03-29T00:14:36+00:00

This was marked as obsolete for quite a while now.. Now it is time to remove it altogether. And while doing this, get rid of first_cpu() as well. Also, remove the redundant setting of cpu_online_mask in smp_prepare_cpus() because the generic code would have already set cpu 0 in cpu_online_mask. Reported-by: Tony Luck Signed-off-by: Srivatsa S.

cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystem

2011-12-21T22:29:42+00:00

This moves the 'cpu sysdev_class' over to a regular 'cpu' subsystem and converts the devices to regular devices. The sysdev drivers are implemented as subsystem interfaces now. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are made available with this conversion.
