Set the max packet size for the default control endpoint on high speed devices to be 64 bytes. High speed devices always have a max packet size of 64 bytes. There's no use setting it to eight for the initial 8 byte descriptor fetch and then issuing (and waiting for) an evaluate context command to update it to 64 bytes for the subsequent control transfers. The USB core guesses that the max packet size on a full speed control endpoint is 64 bytes, and then updates it after the first 8-byte descriptor fetch. Change the initial setup for the xHCI internal representation of the full speed device to have a 64 byte max packet size. Signed-off-by:

Refactor out the code issue, wait for, and parse the event completion code for a configure endpoint command. Modify it to support the evaluate context command, which has a very similar submission process. Add functions to copy parts of the output context into the input context (which will be used in the evaluate context command). Signed-off-by:

Different sections of the xHCI 0.95 specification had opposing requirements for the chain bit in a link transaction request buffer (TRB). The chain bit is used to designate that adjacent TRBs are all part of the same scatter gather list that should be sent to the device. Link TRBs can be in the middle, or at the beginning or end of these chained TRBs. Sections 4.11.5.1 and 6.4.4.1 both stated the link TRB "shall have the chain bit set to 1", meaning it is always chained to the next TRB. However, section 4.6.9 on the stop endpoint command has specific cases for what the hardware must do for a link TRB with the chain bit set to 0. The 0.96 specification errata later cleared up this issue by fixing the 4.11.5.1 and 6.4.4.1 sections to state that a link TRB can have the chain bit set to 1 or 0. The problem is that the xHCI cancellation code depends on the chain bit of the link TRB being cleared when it's at the end of a TD, and some 0.95 xHCI hardware simply stops processing the ring when it encounters a link TRB with the chain bit cleared. Allow users who are testing 0.95 xHCI prototypes to set a module parameter (link_quirk) to turn on this link TRB work around. Cancellation may not work if the ring is stopped exactly on a link TRB with chain bit set, but cancellation should be a relatively uncommon case. Signed-off-by:

SL811 Device detected after removal used to be working in linux-2.6.22 but then broke somewhere between 2.6.22 and 2.6.28. Current hub_port_connect_change() in drivers/usb/core/hub.c won't call usb_disconnect() in case the SL811 driver sets portstatus USB_PORT_FEAT_CONNECTION upon removal. AFAIK the SL811 has only a combined Device Insert/Remove detection bit, therefore use a count to distinguish insert or remove. Signed-Off-By:

On resume from suspend, the driver currently resets the logical state as if it was brought up from halt. This patch uses the dev_pm_ops.resume/restore methods to synchronize the hardware with the memorized logical state, in effect bringing back the accelerometer and backlight to the state prior to suspend. Works for both suspend to ram and hibernation. The patch has zero effect on the running state. Signed-off-by:

The ADM1023 temperature sensor supports higher resolution for its external sensor (sensitivity of 1/8 deg C). This patch makes this higher resolution available through the appropriate temperature sysfs nodes. Curiously, this functionality was available in the 2.4 kernel driver (but formatted in a less helpful manner). Cc: Jean Delvare <khali@linux-fr.org> Signed-off-by:

Enable the coretemp driver on an Intel Atom. I'm not sure if the readings are correct, however - on my 330, the driver reports values between 27 and 41 °C (with core1 being about 8°C hotter than core0, given the same load). Maybe the maximum temperature of 100 °C is wrong for Atom CPUs. Cc: Arjan van de Ven <arjan@infradead.org> Cc: Rudolf Marek <r.marek@assembler.cz> Signed-off-by:

FLEX_ARRAY_INIT(element_size, total_nr_elements) cannot determine if either parameter is valid, so flex arrays which are statically allocated with this interface can easily become corrupted or reference beyond its allocated memory. This removes FLEX_ARRAY_INIT() as a struct flex_array initializer since no initializer may perform the required checking. Instead, the array is now defined with a new interface: DEFINE_FLEX_ARRAY(name, element_size, total_nr_elements) This may be prefixed with `static' for file scope. This interface includes compile-time checking of the parameters to ensure they are valid. Since the validity of both element_size and total_nr_elements depend on FLEX_ARRAY_BASE_SIZE and FLEX_ARRAY_PART_SIZE, the kernel build will fail if either of these predefined values changes such that the array parameters are no longer valid. Since BUILD_BUG_ON() requires compile time constants, several of the static inline functions that were once local to lib/flex_array.c had to be moved to include/linux/flex_array.h. Signed-off-by:
