2014-04-26ARM: orion5x: convert Maxtor Shared Storage II to the Device TreeThomas Petazzoni
This commit converts the Maxtor Shared Storage II Orion5x platform to the Device Tree. The only remaining things not converted are PCI and the special power off method.

2014-04-26ARM: orion5x: convert d2net to Device TreeThomas Petazzoni
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.

2014-04-26ARM: orion5x: convert RD-88F5182 to Device TreeThomas Petazzoni
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. It will ultimately be removed, once we no longer care about non-DT support for Orion5x.

2014-04-26ARM: orion5x: switch to DT interrupts and timerThomas Petazzoni
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 Petazzoni
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 Petazzoni
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 Petazzoni
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.

2014-04-26ARM: orion5x: move interrupt controller node into ocpThomas Petazzoni
The interrupt controller node was located outside of the ocp@f1000000 node, which doesn't make much sense: like any other device, the interrupt controller has registers located in the "Internal Registers Window", so it is much more logical to have it under the ocp@f1000000 node.

2014-04-26Btrfs: limit the path size in send to PATH_MAXChris Mason
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.

2014-04-25mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing partsLinus Torvalds
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.

2014-04-25s390/ccwgroup: Fix memory corruptionChristian Borntraeger
commit 0b60f9ead5d4816e7e3d6e28f4a0d22d4a1b2513 (s390: use device_remove_file_self() instead of device_schedule_callback()) caused random memory corruption on my s390 box. Turns out that the last element of the ccwgroup structure is of dynamic size, so we must move the newly introduced work structure _before_ the zero length array.

2014-04-25kernfs: add back missing error check in kernfs_fop_mmap()Tejun Heo
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 Zhan
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.

2014-04-25USB: io_ti: fix firmware download on big-endian machinesJohan Hovold
During firmware download the device expects memory addresses in big-endian byte order. As the wIndex parameter which hold the address is sent in little-endian byte order regardless of host byte order, we need to use swab16 rather than cpu_to_be16. Also make sure to handle the struct ti_i2c_desc size parameter which is returned in little-endian byte order.

When CONFIG_PCI and CONFIG_PM are not selected, xhci.c gets this warning: drivers/usb/host/xhci.c:409:13: warning: ‘xhci_msix_sync_irqs’ defined but not used [-Wunused-function] Instead of creating nested #ifdefs, this patch fixes it by defining the xHCI PCI stubs as inline. This warning has been in since 3.2 kernel and was caused by commit 421aa841a134f6a743111cf44d0c6d3b45e3cf8c "usb/xhci: hide MSI code behind PCI bars", but wasn't noticed until 3.13 when a configuration with these options was tried Signed-off-by: David Cohen <david.a.cohen@linux.intel.com> Cc: stable@vger.kernel.org # 3.2 Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-04-25xhci: Switch Intel Lynx Point ports to EHCI on shutdown.Denis Turischev
The same issue like with Panther Point chipsets. If the USB ports are switched to xHCI on shutdown, the xHCI host will send a spurious interrupt, which will wake the system. Some BIOS have work around for this, but not all. One example is Compulab's mini-desktop, the Intense-PC2. The bug can be avoided if the USB ports are switched back to EHCI on shutdown. This patch should be backported to stable kernels as old as 3.12, that contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix spurious wakeups after S5 on Haswell" Signed-off-by: Denis Turischev <denis@compulab.co.il> Cc: stable@vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
