The 'max' size passed into the function is measured in number of bits (KEY_MAX, LED_MAX, etc) so we need to convert it accordingly before trying to copy the data out, otherwise we will try copying too much and end up with up with a page fault.

ACPI device enumeration mechanism changed a lot since 3.16-rc1. ACPI device objects with _HID will be enumerated to platform bus by default. For the existing PNP drivers that probe the PNPACPI devices, the device ids are listed explicitly in drivers/acpi/acpi_pnp.c. But ACPI folks will continue their effort on shrinking this id list by converting the PNP drivers to platform drivers, for the devices that don't belong to PNP bus in nature.

The Asus X450 and X550 laptops use a PS/2 touchpad from a new manufacturer called FocalTech: https://bugzilla.kernel.org/show_bug.cgi?id=77391 https://bugzilla.redhat.com/show_bug.cgi?id=1110011 The protocol for these devices is not known at this time, but even without knowing the protocol they need some special handling. They get upset by some of our other PS/2 device probing, and once upset generate random mouse events making things unusable even with an external mouse. This patch adds detection of these devices based on their pnp ids, and when they are detected, treats them as a bare ps/2 mouse. Doing things this way they at least work in their ps/2 mouse emulation mode. Signed-off-by: NHans de Goede <hdegoede@redhat.com> Signed-off-by: NDmitry Torokhov <dmitry.torokhov@gmail.com>

The current codes in gameport and analog joystick drivers for the time accounting have a long-standing problem when the system is running with CPU freq; since the timing is measured via TSC or sample counter, the calculation isn't reliable. In this patch, as a simple fix, use the standard ktime to measure the timing. In case where no high resolution timer is available, use_ktime bool option is provided to both modules. Setting use_ktime=false switches to the old methods.

Many palmas family of PMICs have support for interrupt based power button. This allows the device to notify the processor of external push button events over the shared palmas interrupt. However, this event is generated only during a "press" operation. Software is supposed to poll(sigh!) for detecting a release event. The PMIC also supports ability to power off independent of the software decisions when the button is pressed for a long duration if the PMIC is appropriately configured on the platform. Even though the function is similar to twl4030_pwrbutton, it is substantially different in operation to belong to a new driver of it's own.

This CL uses the bitops hamming weight function (hweight8) to count the number of matching rows for colM & colN. If that number is > 1 ghosting is present. Additionally it removes NULL keys and our one virtual keypress KEY_BATTERY from consideration as these inputs are never physical keypresses.

When tcp retransmit timeout(15mins), the connection will be closed. Pending messages may be lost during this time. So we set tcp user timeout to override the retransmit timeout to the max value. This is OK for ocfs2 since we have disk heartbeat, if peer crash, the disk heartbeat will timeout and it will be evicted, if disk heartbeat not timeout and connection idle for a long time, then this means the cluster enters split-brain state, since fence can't happen, we'd better keep the connection and wait network recover.

This patch series is to fix a possible message lost bug in ocfs2 when network go bad. This bug will cause ocfs2 hung forever even network become good again. The messages may lost in this case. After the tcp connection is established between two nodes, an idle timer will be set to check its state periodically, if no messages are received during this time, idle timer will timeout, it will shutdown the connection and try to reconnect, so pending messages in tcp queues will be lost. This messages may be from dlm. Dlm may get hung in this case. This may cause the whole ocfs2 cluster hung. This is very possible to happen when network state goes bad. Do the reconnect is useless, it will fail if network state is still bad. Just waiting there for network recovering may be a good idea, it will not lost messages and some node will be fenced until cluster goes into split-brain state, for this case, Tcp user timeout is used to override the tcp retransmit timeout. It will timeout after 25 days, user should have notice this through the provided log and fix the network, if they don't, ocfs2 will fall back to original reconnect way. This patch (of 3): Some messages in the tcp queue maybe lost if we shutdown the connection and reconnect when idle timeout. If packets lost and reconnect success, then the ocfs2 cluster maybe hung. To fix this, we can leave the connection there and do the fence decision when idle timeout, if network recover before fence dicision is made, the connection survive without lost any messages. This bug can be saw when network state go bad. It may cause ocfs2 hung forever if some packets lost. With this fix, ocfs2 will recover from hung if network becomes good again.

If we failed to copy from the structure, writing back the flags leaks 31 bits of kernel memory (the rest of the ir_flags field). In any case, if we cannot copy from/to the structure, why should we expect putting just the flags to work? Also make sure ocfs2_info_handle_freeinode() returns the right error code if the copy_to_user() fails. Fixes: ddee5cdb ('Ocfs2: Add new OCFS2_IOC_INFO ioctl for ocfs2 v8.')

Thomas reported that build of x86_64 kernel was failing for him. He is using 32bit tool chain. Problem is that while compiling purgatory, I have not specified -m64 flag. And 32bit tool chain must be assuming -m32 by default. Following is error message. (mini) [~/work/linux-2.6] make scripts/kconfig/conf --silentoldconfig Kconfig CHK include/config/kernel.release UPD include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h UPD include/generated/utsrelease.h CC arch/x86/purgatory/purgatory.o arch/x86/purgatory/purgatory.c:1:0: error: code model 'large' not supported in the 32 bit mode Fix it by explicitly passing appropriate -m64/-m32 build flag for purgatory.
