2011-12-05PCI/sysfs: add per pci device msi[x] irq listing (v5)Neil Horman
This patch adds a per-pci-device subdirectory in sysfs called: /sys/bus/pci/devices/<device>/msi_irqs This sub-directory exports the set of msi vectors allocated by a given pci device, by creating a numbered sub-directory for each vector beneath msi_irqs. For each vector various attributes can be exported. Currently the only attribute is called mode, which tracks the operational mode of that vector (msi vs. msix) Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2011-12-05x86, AMD: Correct align_va_addr documentationBorislav Petkov
Commit dfb09f9b7ab0 ("x86, amd: Avoid cache aliasing penalties on AMD family 15h") introduced a kernel command line parameter called 'align_va_addr' which still refers to arguments used in an earlier version of the patch and which got changed without updating the documentation.

2011-12-05x86: Panic on detection of stack overflowMitsuo Hayasaka
Currently, messages are just output on the detection of stack overflow, which is not sufficient for systems that need a high reliability. This is because in general the overflow may corrupt data, and the additional corruption may occur due to reading them unless systems stop. This patch adds the sysctl parameter kernel.panic_on_stackoverflow and causes a panic when detecting the overflows of kernel, IRQ and exception stacks except user stack according to the parameter. It is disabled by default. Signed-off-by: Mitsuo Hayasaka <mitsuo.hayasaka.hu@hitachi.com> Cc: yrl.pp-manager.tt@hitachi.com Cc: Randy Dunlap <rdunlap@xenotime.net> Cc: "H.

2011-12-03net: Add Open vSwitch kernel components.Jesse Gross
Open vSwitch is a multilayer Ethernet switch targeted at virtualized environments. In addition to supporting a variety of features expected in a traditional hardware switch, it enables fine-grained programmatic extension and flow-based control of the network. This control is useful in a wide variety of applications but is particularly important in multi-server virtualization deployments, which are often characterized by highly dynamic endpoints and the need to maintain logical abstractions for multiple tenants. The Open vSwitch datapath provides an in-kernel fast path for packet forwarding. It is complemented by a userspace daemon, ovs-vswitchd, which is able to accept configuration from a variety of sources and translate it into packet processing rules. See http://openvswitch.org for more information and userspace utilities. Signed-off-by: Jesse Gross <jesse@nicira.com>

2011-11-30Input: add generic GPIO-tilt driverHeiko Stübner
There exist tilt switches that simply report their tilt-state via some gpios. The number and orientation of their axes can vary depending on the switch used and the build of the device. Also two or more one-axis switches could be combined to provide multi-dimensional orientation. One example of a device using such a switch is the family of Qisda ebook readers, where the switch provides information about the landscape / portrait orientation of the device. The example in Documentation/input/gpio-tilt.txt documents exactly this one-axis device. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2011-11-26ARM: move iotable mappings within the vmalloc regionNicolas Pitre
In order to remove the build time variation between different SOCs with regards to VMALLOC_END, the iotable mappings are now allocated inside the vmalloc region. This allows for VMALLOC_END to be identical across all machines. The value for VMALLOC_END is now set to 0xff000000 which is right where the consistent DMA area starts. To accommodate all static mappings on machines with possible highmem usage, the default vmalloc area size is changed to 240 MB so that VMALLOC_START is no higher than 0xf0000000 by default.

The helper routine is meant to be used by the regulator drivers to extract the regulator_init_data structure from the data that is passed from device tree.

Similarly the regulator<-->parent/supply mapping is handled in subsequent patches. Also add documentation for regulator bindings to be used to pass regulator_init_data struct information from device tree. Some of the regulator properties which are linux and board specific, are left out since its not clear if they can be in someway embedded into the kernel or passed in from DT. They will be revisited later. Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
