* ieee802154: move wpan-phy.h to cfg802154.hAlexander Aring2014-10-255-5/+5
| | | | | | | | | | | The wpan-phy header contains the wpan_phy struct information. Later this header will be have similar function like cfg80211 header. The cfg80211 header contains the wiphy struct which is identically the wpan_phy struct inside 802.15.4 subsystem.

* at86rf230: fix enable_irq handling on async spiAlexander Aring2014-10-251-80/+77
| | | | | | | | | | | Sometimes the async state function is call in an context where the spi irq is diabled. This patch fix the handling to enable the irq when spi_async failed in the async state change calling chain. We do this by a context parameter irq_enable and evaluate this parameter when spi_async failed instead of returning spi_async errno.

* at86rf230: fix race conditionAlexander Aring2014-10-251-1/+1
| | | | | | | | | | | | | When the driver waits for a tx completion currently the driver direct enables the irq. When we switching to RX_AACK_ON some steps afterwards the driver could receive a new frame and request resources which are already in use, for example irq state change resource. To be sure there are no new interrupts when we switching to RX_AACK_ON, we enable the irq when state change to RX_AACK_ON was completed.

In this case, we should first test I2C_I2SR[IAL], and clear this bit if it is set, and then I2C controller default to slave receive mode.

| * | | Input: xen-kbdfront - free grant table entry in xenkbd_disconnect_backendChang Huaixin2014-10-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xenkbd_disconnect_backend doesn't free grant table entry. This bug affects live migration. xenkbd_disconnect_backend uses gnttab_end_foreign_access_ref to handle grant table entry which doesn't really free an entry. Thus every time we do xenkbd_resume, grant table entry increses by one. As an grant table entry occupies 8 bytes, an grant table page has at most 512 entries. Every 512 times we do xenkdb_resume, grant table pages increses by one. After around 3500 times of live migration, grant table pages will increase by 7, causing too many pages to populate and hitting max_pages limit when assigning pages.Thus assign_pages will fail, so will live migration.

| * | | Input: i8042 - disable active multiplexing by defaultDmitry Torokhov2014-10-112-274/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Active multiplexing is a nice feature as it allows several pointing devices (such as touchpad and external mouse) use their native protocols at the same time. Unfortunately many manufacturers do not implement the feature properly even though they advertise it. The problematic implementations are never fixed, since Windows by default does not use this mode, and move from one BIOS/model of laptop to another. When active multiplexing is broken turning it on usually results in touchpad, keyboard, or both unresponsive. With PS/2 usage on decline (most of PS/2 devices in use nowadays are internal laptop touchpads), I expect number of users who have laptops with working MUX implementation, docking stations with external PS/2 ports, and who are still using external PS/2 mice, to be rather small. Let's flip the default to be OFF and allow activating it through i8042.nomux=0 kernel option. We'll also keep DMI table where we can record known good models.
