Calling irq_find_mapping from outside a irq_{enter,exit} section is unsafe and produces ugly messages if CONFIG_PROVE_RCU is enabled: If coming from the idle state, the rcu_read_lock call in irq_find_mapping will generate an unpleasant warning: <quote> =============================== [ INFO: suspicious RCU usage. ] 3.16.0-rc1+ #135 Not tainted ------------------------------- include/linux/rcupdate.h:871 rcu_read_lock() used illegally while idle! other info that might help us debug this: RCU used illegally from idle CPU! rcu_scheduler_active = 1, debug_locks = 0 RCU used illegally from extended quiescent state! 1 lock held by swapper/0/0: #0: (rcu_read_lock){......}, at: [<ffffffc00010206c>] irq_find_mapping+0x4c/0x198 </quote> As this issue is fairly widespread and involves at least three different architectures, a possible solution is to add a new handle_domain_irq entry point into the generic IRQ code that the interrupt controller code can call. This new function takes an irq_domain, and calls into irq_find_domain inside the irq_{enter,exit} block. An additional "lookup" parameter is used to allow non-domain architecture code to be replaced by this as well. Interrupt controllers can then be updated to use the new mechanism. This code is sitting behind a new CONFIG_HANDLE_DOMAIN_IRQ, as not all architectures implement set_irq_regs (yes, mn10300, I'm looking at you...).

Pull file locking bugfixes from Jeff Layton: "Most of these patches are to fix a long-standing regression that crept in when the BKL was removed from the file-locking code. The code was converted to use a conventional spinlock, but some fl_release_private ops can block and you can end up sleeping inside the lock.

Azael Avalos authored
This driver adds support for the built-in accelereometer found on recent Toshiba laptops with HID TOS620A. This driver receives ACPI notify events 0x80 when the sensor detects a sudden move or a harsh vibration, as well as an ACPI notify event 0x81 whenever the movement or vibration has been stabilized. Also provides sysfs entries to get/set the desired protection level and reseting the HDD protection interface.
