arch: ia64: Remove rest of perfmon support

2021-01-22T06:42:20Z

Perfmon support (used by oprofile earlier) was removed by commit ecf5b72d5f66 ("ia64: Remove perfmon") earlier, but it missed few files to remove/update. Clean it up.

treewide: Add SPDX license identifier for more missed files

2019-05-21T08:50:45Z

Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

proc: introduce proc_create_single{,_data}

2018-05-16T05:23:35Z

Variants of proc_create{,_data} that directly take a seq_file show callback and drastically reduces the boilerplate code in the callers. All trivial callers converted over. Signed-off-by: Christoph Hellwig

ia64/palinfo: Convert to hotplug state machine

2016-11-09T22:45:30Z

Install the callbacks via the state machine and let the core invoke the callbacks on the already online CPUs. The removal of the files happens now in the prepare down stage as there is no reason to keep them around until the cpu has actually died.

ia64, palinfo: Fix CPU hotplug callback registration

2014-03-20T12:43:40Z

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 palinfo code in ia64 by using this latter form of callback registration.

[IA64] Delete __cpuinit usage from all ia64 users

2013-06-24T22:44:27Z

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: Don't use create_proc_read_entry()

2013-04-29T19:41:58Z

Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead. Signed-off-by: David Howells cc: Tony Luck cc: Fenghua Yu cc: linux-ia64@vger.kernel.org Signed-off-by: Al Viro

palinfo fixes

2013-04-09T18:09:44Z

* check for proc_mkdir() failures * fix buffer overrun - sizeof(format string) is *not* enough to hold sprintf() result. * use proc_remove_subtree(); life's much easier with it Signed-off-by: Al Viro
