git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: "These include a fix for a recent ACPI regression related to device notifications, intel_idle fix related to IvyTown support, fix for a buffer size issue in ACPICA, PM core fix related to the "freeze" sleep state, four fixes for various types of breakage in cpufreq drivers, a PNP workaround for a wrong memory region size in ACPI tables, and a fix and cleanup for the ACPI tools Makefile. Specifics: - Fix for broken ACPI notifications on some systems caused by a recent ACPI hotplug commit that blocked the propagation of unknown type notifications to device drivers inadvertently. - intel_idle fix to make the IvyTown C-states handling (added recently) work as intended which now is broken due to missing braces. From Christoph Jaeger. - ACPICA fix to make it allocate buffers of the right sizes for the Generic Serial Bus operation region access. From Lv Zheng. - PM core fix unblocking cpuidle before entering the "freeze" sleep state which causes that state to be able to actually save more energy than runtime idle. - Configuration and build fixes for the highbank and powernv cpufreq drivers from Kefeng Wang and Srivatsa S Bhat. - Coccinelle warning fix related to error pointers for the unicore32 cpufreq driver from Duan Jiong. - Integer overflow fix for the ppc-corenet cpufreq driver from Geert Uytterhoeven. - Workaround for BIOSes that don't report the entire Intel MCH area in their ACPI tables from Bjorn Helgaas. - ACPI tools Makefile fix and cleanup from Thomas Renninger" * tag 'pm+acpi-3.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / notify: Do not block unknown type notifications in root handler PNP: Work around BIOS defects in Intel MCH area reporting cpufreq: highbank: fix ARM_HIGHBANK_CPUFREQ dependency warning cpufreq: ppc: Fix integer overflow in expression cpufreq, powernv: Fix build failure on UP cpufreq: unicore32: replace IS_ERR and PTR_ERR with PTR_ERR_OR_ZERO PM / suspend: Make cpuidle work in the "freeze" state intel_idle: fix IVT idle state table setting ACPICA: Fix buffer allocation issue for generic_serial_bus region accesses. tools/power/acpi: Minor bugfixes

2014-04-26ARM: orion5x: convert d2net to Device TreeThomas Petazzoni6-378/+351
This commit converts the LaCie d2 Network platform to the Device Tree. All devices except LEDs are converted, because the LED code needs a non-LED GPIO to be set to a given value for the LEDs to work, and this cannot yet be easily represented in DT. Also, references to the LaCie Big Disk Network platform are lost, because this platform apparently has exactly the same hardware support as the LaCie d2 Network, so their Device Tree files would be identical.

This commit converts the RD-88F5182 platform to the Device Tree. All devices except the PCI are converted to the Device Tree. It is worth noting that: * The PCI description for the DT case is kept in board-rd88f5182.c. * The existing non-DT support in rd88f5182-setup.c is kept as is, in order to allow testing of a given platform in both DT and non-DT cases.

2014-04-26ARM: orion5x: switch to DT interrupts and timerThomas Petazzoni4-14/+50
This commit switches the Orion5x platforms described through DT to use a DT-defined interrupt controller and timer. This involves: * Describing in the DT the bridge interrupt controller, which is a child interrupt controller to the main one, which is used for timer and watchdog interrupts. * Describing in the DT the timer. * Adding in the DT the interrupt specifications for the watchdog. * Selecting the ORION_IRQCHIP and ORION_TIMER drivers to be compiled. * Change board-dt.c to no longer have an ->init_time() callback, since the default callback will work fine: it calls clocksource_of_init() and of_clk_init(), as needed. * Implement a multi-IRQ handler for non-DT platforms in mach-orion5x/irq.c.

2014-04-26ARM: orion: switch to a per-platform handle_irq() functionThomas Petazzoni3-45/+73
Moving to the Device Tree implies having CONFIG_MULTI_IRQ_HANDLER enabled, even for non-DT platforms (if we want both DT and non-DT platforms to be supported in a single kernel). However, the common CONFIG_MULTI_IRQ_HANDLER handler for non-DT platforms in plat-orion/irq.c doesn't match the needs of Orion5x. Also, it doesn't make much sense for orion_irq_init() to register the multi-IRQ handler: orion_irq_init() is called once for each IRQ cause/mask tuple, while the multi-IRQ handler only needs to be registered once. To solve this problem, we move the multi-IRQ handle in per-platform code: mach-kirkwood/irq.c and mach-dove/irq.c. The Orion5x variant will be introduced in a followup commit. Of course, this code will ultimately be completely removed once all boards are converted to the Device Tree.

2014-04-26ARM: orion5x: convert to use 'clocks' property for UART controllersThomas Petazzoni2-3/+2
Until the previous commit, the Orion5x clocks were not described in the Device Tree. Now that they are described in the Device Tree, we can replace the manual 'clock-frequency' property in the UART nodes by a nicer 'clocks' reference in those UART nodes. This commit consequently removes the 'clock-frequency' property from the LaCie edmini_v2 board, which is at this point the only Orion5x board converted to the Device Tree.

2014-04-26ARM: orion5x: convert DT to use the mvebu-mbus driverThomas Petazzoni4-130/+182
This commit switches the Orion5x Device Tree files to use the DT representation and probing for the mvebu-mbus driver. The changes are mainly: * Re-organize the DT to follow the same organization as the one used on Armada 370/XP, which is needed for mvebu-mbus to work: a top-level soc { ... } node, which corresponds to the MBus bus, and a sub-node internal-regs { ... } for all peripherals whose register sit only in the "Internal Register Window". This change re-indents by one level the definition of all nodes in the Device Tree, which explains the large change. * Use custom functions orion5x_dt_init_early() and orion5x_dt_init_time() instead of orion5x_init_early() and orion5x_timer_init() as we now want the MBus driver to be probed from the Device Tree. We still use the old-style timer initialization, but that will be changed in a followup commit.

2014-04-26Btrfs: limit the path size in send to PATH_MAXChris Mason1-0/+5
fs_path_ensure_buf is used to make sure our path buffers for send are big enough for the path names as we construct them. The buffer size is limited to 32K by the length field in the struct. But bugs in the path construction can end up trying to build a huge buffer, and we'll do invalid memmmoves when the buffer length field wraps. This patch is step one, preventing the overflows.

2014-04-26ARM: mvebu: don't use clocks property in UART node for Netgear RN2120Thomas Petazzoni1-1/+0
The Netgear RN2120 was not using the same strategy as the other Armada 370/375/38x/XP boards: it was using a 'clocks' property and not the 'clock-frequency' property in its UART controller Device Tree node. However, now that this clock reference is present at the SoC-level, there is no point in duplicating it at the board-level.

2014-04-26ARM: mvebu: remove clock-frequency of serial port Device Tree nodesThomas Petazzoni13-24/+0
Now that the Armada 370/375/38x/XP SoC-level Device Tree files have the proper "clocks" property in their UART controllers node, it is no longer useful to have the clock-frequency property defined in the board-level Device Tree files. Therefore, this commit gets rid of all the useless 'clock-frequency' properties.

2014-04-26ARM: mvebu: use clocks property for serial portsThomas Petazzoni4-0/+8
Back when the Armada 370 and Armada XP initial support was introduced, the only way to pass the clock frequency to the of_serial driver was through a clock-frequency Device Tree property. Thanks to 0bbeb3c3e84bc963d1c66661e082d207023b0e5c ('of serial port driver - add clk_get_rate() support'), it is possible to use the standard 'clocks' DT property to reference the clock used for a particular UART controller. This clock is then used by the of_serial driver to retrieve the clock rate. This commit modifies the SoC-level Device Tree files of Armada 370, Armada XP, Armada 375 and Armada 38x to use this possibility. Since there is no gatable clock for the UART controllers, we simply reference the TCLK, which is the main SoC clock for the peripherals.

2014-04-26mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing partsLinus Torvalds6-33/+111
The mmu-gather operation 'tlb_flush_mmu()' has done two things: the actual tlb flush operation, and the batched freeing of the pages that the TLB entries pointed at. This splits the operation into separate phases, so that the forced batched flushing done by zap_pte_range() can now do the actual TLB flush while still holding the page table lock, but delay the batched freeing of all the pages to after the lock has been dropped. This in turn allows us to avoid a race condition between set_page_dirty() (as called by zap_pte_range() when it finds a dirty shared memory pte) and page_mkclean(): because we now flush all the dirty page data from the TLB's while holding the pte lock, page_mkclean() will be held up walking the (recently cleaned) page tables until after the TLB entries have been flushed from all CPU's.

2014-04-25kernfs: add back missing error check in kernfs_fop_mmap()Tejun Heo1-0/+2
While updating how mmap enabled kernfs files are handled by lockdep, 9b2db6e18945 ("sysfs: bail early from kernfs_file_mmap() to avoid spurious lockdep warning") inadvertently dropped error return check from kernfs_file_mmap(). The intention was just dropping "if (ops->mmap)" check as the control won't reach the point if the mmap callback isn't implemented, but I mistakenly removed the error return check together with it. This led to Xorg crash on i810 which was reported and bisected to the commit and then to the specific change by Tobias.

2014-04-25kernfs: fix a subdir count leakJianyu Zhan1-3/+6
Currently kernfs_link_sibling() increates parent->dir.subdirs before adding the node into parent's chidren rb tree. Because it is possible that kernfs_link_sibling() couldn't find a suitable slot and bail out, this leads to a mismatch between elevated subdir count with actual children node numbers. This patches fix this problem, by moving the subdir accouting after the actual addtion happening.
