2014-09-05mm: memcontrol: revert use of root_mem_cgroup res_counterJohannes Weiner1-25/+78
Dave Hansen reports a massive scalability regression in an uncontained page fault benchmark with more than 30 concurrent threads, which he bisected down to 05b843012335 ("mm: memcontrol: use root_mem_cgroup res_counter") and pin-pointed on res_counter spinlock contention. That change relied on the per-cpu charge caches to mostly swallow the res_counter costs, but it's apparent that the caches don't scale yet. Revert memcg back to bypassing res_counters on the root level in order to restore performance for uncontained workloads.

2014-09-05Export sync_filesystem() for modular ->remount_fs() useAnton Altaparmakov1-1/+1
This patch changes sync_filesystem() to be EXPORT_SYMBOL(). The reason this is needed is that starting with 3.15 kernel, due to Theodore Ts'o's commit 02b9984d6408 ("fs: push sync_filesystem() down to the file system's remount_fs()"), all file systems that have dirty data to be written out need to call sync_filesystem() from their ->remount_fs() method when remounting read-only. As this is now a generically required function rather than an internal only function it should be EXPORT_SYMBOL() so that all file systems can call it.

2014-09-04nohz: Restore NMI safe local irq work for local nohz kickFrederic Weisbecker2-6/+15
The local nohz kick is currently used by perf which needs it to be NMI-safe. Recent commit though (7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9) changed its implementation to fire the local kick using the remote kick API. It was convenient to make the code more generic but the remote kick isn't NMI-safe.

2014-09-04ARM: dts: dra7-evm: Add vtt regulator supportLokesh Vutla1-1/+26
DRA7 evm REV G and later boards uses a vtt regulator for DDR3 termination and this is controlled by gpio7_11. This gpio is configured in boot loader. gpio7_11, which is only available only on Pad A22, in previous boards, is connected only to an unused pad on expansion connector EXP_P3 and is safe to be muxed as GPIO on all DRA7-evm versions (without a need to spin off another dts file). Since gpio7_11 is used to control VTT and should not be reset or kept in idle state during boot up else VTT will be disconnected and DDR gets corrupted. So, as part of this change, mark gpio7 as no-reset and no-idle on init.

2014-09-03ACPI / cpuidle: fix deadlock between cpuidle_lock and cpu_hotplug.lockJiri Kosina1-2/+2
There is a following AB-BA dependency between cpu_hotplug.lock and cpuidle_lock: 1) cpu_hotplug.lock -> cpuidle_lock enable_nonboot_cpus() _cpu_up() cpu_hotplug_begin() LOCK(cpu_hotplug.lock) cpu_notify() ... acpi_processor_hotplug() cpuidle_pause_and_lock() LOCK(cpuidle_lock) 2) cpuidle_lock -> cpu_hotplug.lock acpi_os_execute_deferred() workqueue ... acpi_processor_cst_has_changed() cpuidle_pause_and_lock() LOCK(cpuidle_lock) get_online_cpus() LOCK(cpu_hotplug.lock) Fix this by reversing the order acpi_processor_cst_has_changed() does thigs -- let it first execute the protection against CPU hotplug by calling get_online_cpus() and obtain the cpuidle lock only after that (and perform the symmentric change when allowing CPUs hotplug again and dropping cpuidle lock).

2014-09-03ACPI / scan: not cache _SUN value in struct acpi_device_pnpYasuaki Ishimatsu2-8/+8
The _SUN device indentification object is not guaranteed to return the same value every time it is executed, so we should not cache its return value, but rather execute it every time as needed. If it is cached, an incorrect stale value may be used in some situations. This issue was exposed by commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace). Fix it by avoiding to cache the return value of _SUN.

2014-09-03toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()Dan Carpenter1-6/+12
The current code just returns -EINVAL because mode can't be equal to both 1 and 2. Also this function is messy so I have cleaned it up: 1) Remove initializers like "int time = -1". Initializing variables to garbage values turns off GCC's uninitialized variable warnings so it can lead to bugs. 2) Use kstrtoint() instead of sscanf(). 3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1 and 2. 4) Don't check for "mode == -1" because that can't happen. 5) Preserve the error code from toshiba_kbd_illum_status_set().
