| * | hwmon: (w83781d) Make ISA interface depend on CONFIG_ISAWolfgang Grandegger2008-10-171-280/+393
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Probing the ISA bus on systems without ISA bus may hang the system. This patch makes the ISA bus related code depend on the kernel configuration parameter CONFIG_ISA. It moves ISA bus related code into one #ifdef CONFIG_ISA ... #endif block and adds some helper function.

| * | hwmon: (w83781d) Detect alias chipsJean Delvare2008-10-171-13/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The W83781D and W83782D can be accessed either on the I2C bus or the ISA bus. We must not access the same chip through both interfaces. So far we were relying on the user passing the correct ignore parameter to skip the registration of the I2C interface as suggested by sensors-detect, but this is fragile: the user may load the w83781d driver without running sensors-detect, and the i2c bus numbers are not stable across reboots and hardware changes. So, better detect alias chips in the driver directly, and skip any I2C chip which is obviously an alias of the ISA chip. This is done by comparing the value of 26 selected registers.

| * | hwmon: (it87) Fix thermal sensor type valuesJean Delvare2008-10-171-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The it87 driver doesn't follow the standard sensor type values as documented in Documentation/hwmon/sysfs-interface. It uses value 2 for thermistors instead of value 4. This causes "sensors" to tell the user that the chip is setup for a transistor while it is actually setup for a thermistor. Using value 4 for thermistors solves the problem. For compatibility reasons, we still accept value 2 but emit a warning message so that users update their configuration files.

| * | hwmon: (lm78) Fix I/O resource conflict with PNPJean Delvare2008-10-171-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only request I/O ports 0x295-0x296 instead of the full I/O address range. This solves a conflict with PNP resources on a few motherboards. Also request the I/O ports in two parts (4 low ports, 4 high ports) during device detection, otherwise the PNP resource make the request (and thus the detection) fail. This is the exact same fix that was applied to driver w83781d in March 2008 to address the same problem: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2961cb22ef02850d90e7a12c28a14d74e327df8d Signed-off-by: Jean Delvare <khali@linux-fr.org>

| * | hwmon: (ams) Convert to a new-style i2c driverJean Delvare2008-10-173-41/+48

Here is a naive approach of this conversion. Basically it is moving the i2c device creation from the ams driver to the i2c-powermac driver. This should work, but I suspect we could come up with something cleaner by declaring the i2c device as part of the platform setup. This could be done later by someone more familiar with openfirmware-based platforms than I am myself. One nice thing brought by this conversion is that the ams driver should be loaded automatically on systems where is is needed (at least when the I2C interface to the chip is used) providing coldplug-aware user-space environment.

| * | | [SCSI] libiscsi: rename host reset to target resetMike Christie2008-10-133-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had this in my patchset to add target reset support, but it got dropped due to patching conflicts. This initial patch just renames the function and users. We are actually just dropping the session, and so this does not have anything to do with the host exactly. It does for software iscsi because we allocate a host per session, but for cxgb3i this makes no sense.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some endpoint code was using unsigned int and some was using uint64_t. This converts it all to uint64_t. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * | | [SCSI] libiscsi: Support drivers initiating session removalMike Christie2008-10-135-12/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the driver knows when hardware is removed like with cxgb3i, bnx2i, qla4xxx and iser then we will want to remove the sessions/devices that are bound to that device before removing the host. cxgb3i and in the future bnx2i will remove the host and that will remove all the sessions on the hba. iser can call iscsi_kill_session when it gets an event that indicates that a hca is removed. And when qla4xxx is hooked in to the lib (it is only hooked into the class right now) it can call iscsi remove host like the partial offload card drivers.

| * | | [SCSI] libiscsi: fix data corruption when target has to resend data-in packetsMike Christie2008-10-132-30/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iscsi_tcp was updating the exp_statsn (exp_statsn acknowledges status and tells the target it is ok to let the resources for a iscsi pdu to be reused) before it got all the data for pdu read into OS buffers. Data corruption was occuring if something happens to a packet and the network layer requests a retransmit, and the initiator has told the target about the udpated exp_statsn ack, then the target may be sending data from a buffer it has reused for a new iscsi pdu. This fixes the problem by having the LLD (iscsi_tcp in this case) just handle the transferring of data, and has libiscsi handle the processing of status (libiscsi completion processing is done after LLD data transfers are complete).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason these messages ended up being printed with KERN_INFO rendering them invisible to pretty much everyone.
