The LIS302DL accelerometer chip has a 'click' feature which can be used to detect sudden motion on any of the three axis. Configuration data is passed via spi platform_data and no action is taken if that's not specified, so it won't harm any existing platform. To make the configuration effective, the IRQ lines need to be set up appropriately. This patch also adds a way to do that from board support code. The DD_* definitions were factored out to an own enum because they are specific to LIS3LV02D devices. Signed-off-by:

Now that there is no need to hookup on the open/close of the joystick, it's possible to use the simplified interface input_polled_device, instead of creating our own kthread. [randy.dunlap@oracle.com: fix Kconfig] [randy.dunlap@oracle.com: fix Kconfig some more] Signed-off-by:

After measurement on my laptop, it seems that turning off the device does not bring any energy saving (within 0.1W precision). So let's keep the device always on. It simplifies the code, and it avoids the problem of reading a wrong value sometimes just after turning the device on. Moreover, since commit ef2cfc79 had been too zealous, the device was actually never turned off anyway. This patch also restores the damages done by this commit concerning the initialisation/poweroff. Also do more clean up with the usage of the lis3_dev global variable. Signed-off-by:

Furthermore, notice that the initial checks: if (!node->rb_left) child = node->rb_right; else if (!node->rb_right) child = node->rb_left; else { ... } guarantee that old->rb_right is set in the final else branch, therefore we can omit checking that again.

There are two cases when a node, having 2 childs, is erased: 'normal case': the successor is not the right-hand-child of the node to be erased 'special case': the successor is the right-hand child of the node to be erased Here some ascii-art, with following symbols (referring to the code): O: node to be deleted N: the successor of O P: parent of N C: child of N L: some other node normal case: O N / \ / \ / \ / \ L \ L \ / \ P ----> / \ P / \ / \ / / N C \ / \ \ C / \ special case: O|P N / \ / \ / \ / \ L \ L \ / \ N ----> / C \ / \ \ C / \ Notice that for the special case we don't have to reconnect C to N.

There is a call to write_lock() in gen_pool_destroy which is not balanced by any corresponding write_unlock(). This causes problems with preemption because the preemption-disable counter is incremented in the write_lock() call, but never decremented by any call to write_unlock(). This bug is gen_pool_destroy, and one of them is non-x86 arch-specific code. Signed-off-by:

The console blank timer is currently hardcoded to 10*60 seconds which might be annoying on systems with no input devices attached to wake up the console again. Especially during development, disabling the screen saver can be handy - for example when debugging the root fs mount mechanism or other scenarios where no userspace program could be started to do that at runtime from userspace. This patch defines a core_param for the variable in charge which allows users to entirely disable the blank feature at boot time by setting it 0. The value can still be overwritten at runtime using the standard ioctl call - this just allows to conditionally change the default. Signed-off-by:

Add EISA IDs for Network Peripherals FDDI boards. Descriptions taken from the respective EISA configuration files. It's unlikely we'll ever support these cards, the problem being the lack of documentation. Assuming the policy for the EISA ID database is the same as for PCI I'm sending these entries for the sake of completeness. Signed-off-by:

Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval. Signed-off-by:

For example: hex_dump_to_buffer("AB", 2, 16, 1, buf, 100, 0); pr_info("[%s]\n", buf); I'd expect the output to be "[41 42]", but actually it's "[41 42 ]" This patch also makes the required buf to be minimum. To print the hex format of "AB", a buf with size 6 should be sufficient, but hex_dump_to_buffer() required at least 8. Signed-off-by:Li Zefan <lizf@cn.fujitsu.com> Acked-by:

Round the slow work queue's cull and OOM timeouts to whole second boundary with round_jiffies(). The slow work queue uses a pair of timers to cull idle threads and, after OOM, to delay new thread creation. This patch also extracts the mod_timer() logic for the cull timer into a separate helper function. By rounding non-time-critical timers such as these to whole seconds, they will be batched up to fire at the same time rather than being spread out. This allows the CPU wake up less, which saves power. Signed-off-by:
