[PATCH V2] clocksource: register cpu notifier to remove timer from dying CPU

by Viresh Kumar

clocksource core is using add_timer_on() to run clocksource_watchdog() on all CPUs one by one. But when a core is brought down, clocksource core doesn't remove this timer from the dying CPU. And in this case timer core gives this (Gives this only with unmerged code, anyway in the current code as well timer core is migrating a pinned timer to other CPUs, which is also wrong: http://www.gossamer-threads.com/lists/linux/kernel/1898117) migrate_timer_list: can't migrate pinned timer: ffffffff81f06a60, timer->function: ffffffff810d7010,deactivating it Modules linked in: CPU: 0 PID: 1932 Comm: 01-cpu-hotplug Not tainted 3.14.0-rc1-00088-gab3c4fd #4 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 0000000000000009 ffff88001d407c38 ffffffff817237bd ffff88001d407c80 ffff88001d407c70 ffffffff8106a1dd 0000000000000010 ffffffff81f06a60 ffff88001e04d040 ffffffff81e3d4c0 ffff88001e04d030 ffff88001d407cd0 Call Trace: [<ffffffff817237bd>] dump_stack+0x4d/0x66 [<ffffffff8106a1dd>] warn_slowpath_common+0x7d/0xa0 [<ffffffff8106a24c>] warn_slowpath_fmt+0x4c/0x50 [<ffffffff810761c3>] ? __internal_add_timer+0x113/0x130 [<ffffffff810d7010>] ? clocksource_watchdog_kthread+0x40/0x40 [<ffffffff8107753b>] migrate_timer_list+0xdb/0xf0 [<ffffffff810782dc>] timer_cpu_notify+0xfc/0x1f0 [<ffffffff8173046c>] notifier_call_chain+0x4c/0x70 [<ffffffff8109340e>] __raw_notifier_call_chain+0xe/0x10 [<ffffffff8106a3f3>] cpu_notify+0x23/0x50 [<ffffffff8106a44e>] cpu_notify_nofail+0xe/0x20 [<ffffffff81712a5d>] _cpu_down+0x1ad/0x2e0 [<ffffffff81712bc4>] cpu_down+0x34/0x50 [<ffffffff813fec54>] cpu_subsys_offline+0x14/0x20 [<ffffffff813f9f65>] device_offline+0x95/0xc0 [<ffffffff813fa060>] online_store+0x40/0x90 [<ffffffff813f75d8>] dev_attr_store+0x18/0x30 [<ffffffff8123309d>] sysfs_kf_write+0x3d/0x50 This patch tries to fix this by registering cpu notifiers from clocksource core, only when we start clocksource-watchdog. And if on the CPU_DEAD notification it is found that dying CPU was the CPU on which this timer is queued on, then it is removed from that CPU and queued to next CPU.

[PATCH 0/3] perf tools: Add libdw DWARF post unwind support for ARM64

by Jean Pihet

Adding libdw DWARF post unwind support, which is part of elfutils-devel/libdw-dev package from version 0.158. Also includes the test suite for dwarf unwinding, by adding the arch specific test code and the perf_regs_load function. This series depends on the following kernel patches series: - AARCH64 unwinding support [1]. Already mainlined. - ARM libdw integration [2], and on the changes from the branch for: - libdw AARCH64 unwinding support [3]. [1] http://www.spinics.net/lists/arm-kernel/msg304483.html [2] https://lkml.org/lkml/2014/5/6/366 [3] https://git.fedorahosted.org/cgit/elfutils.git/log/?h=mjw/aarch64-unwind ToDo: investigate the libdw unwinding problem with compat binaries (i.e. ARMv7 binaries running on ARMv8). Since this functionality works ok with libunwind, the problem should be in libdw compat support [3].

[PATCH] sched: hmp: Change small task packing defaults for all

by Chris Redpath

Hi all, this is a proposal to change the default small task packing for TC2 to 'enabled' rather than just present (aligned with all other platforms) and to change the default packing_limit to 650 on all platforms to match the existing TC2 default. This should by default restrict packing so that it will not cause frequency of the little CPUs to go above 80%. Of course, the presence of bigger tasks can still cause frequency to go up.

[PATCH] arm: Describe required sort order for textofs-y (TEXT_OFFSET)

by Daniel Thompson

The section of the makefile that determines the TEXT_OFFSET is sorted by address so that, in multi-arch kernel builds, the architecture with the most stringent requirements for the kernel base address gets to define TEXT_OFFSET. The comment should reflect that.
