Looks like we were casting a value into a union and sparse doesn't like that. Why not just assign it directly to the appropriate field? Signed-off-by: Jesse Barnes <jbarnes@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

John Hawkes authored
Some have noticed that the overlapping sched domains code doesn't quite work as intended (it results in disjoint domains on some machines), and that a top level, machine spanning domain is needed. This patch from John Hawkes adds it to the ia64 code. This allows processes to run on all CPUs in large systems, though balancing is limited. It should go to Linus soon now otherwise large systems will only have ~16p (depending on topology) usable by the scheduler. I sanity checked it on a small system after rediffing John's original, and he's done some testing on very large systems. Nick, can you buy off on the sched.c change? Alternatively, do you want to send that fix separately John? Nick did indeed ACK this change, but it isn't dependent on this ia64 specific part ... so it's going to be submitted separately.

There is a rare deadlock condition during unwind script creation. If build_script() is interrupted in the middle of creating the script, it holds the script write lock. If the interrupt handler needs to call unwind for some failure condition, unwind will try to read the incomplete script and will deadlock on the script lock. The fix is to disable interrupts while building the script, so interrupt handlers never see partial scripts. Promoting spin_lock_irqsave() from script_new() to find_save_locs() changes the indentation, so the patch looks bigger than it really is.

During peak utilization periods, the first interface on a node has an inordinately large amount of contention. This is due to all cpus starting their scan for an interface at 0. This patch distributes that based upon the slice the requesting cpu is attached to. Signed-off-by: Robin Holt Signed-off-by: Tony Luck <tony.luck@intel.com>

The SN2 Block Transfer Engine occassionally fails to send a notification that it has completed a transfer to the kernel. This patch adds a timeout mechanism which will detect the failure, reset the interface, and then retry the transfer. Signed-off-by: Robin Holt Signed-off-by: Tony Luck <tony.luck@intel.com>

If all bte interfaces are in use, the current code will leave the bte pointer set when exiting from the loop trying to locate an interface to use. This results in two processes using the same interface and both trying to free the same one. With a premptible kernel, this results in the preempt count getting off.

This includes a fuller definition of the 8250 and compatible bits, and adding notes where the definition varies between different chips. This also fixes the following build error: drivers/serial/8250.c:185: error: `UART_FCR_R_TRIG_10'

Some serial drivers receive their serial port device information via the device model. This unfortunately means that the selected port may not be available when the console subsystem initialises, so we must keep trying to register the console after each port is added.

This allows 8250 PCI ports to register with their correct device structures.

Russell King authored
serial8250_register_port()/serial8250_unregister_port() has the capability of registering ports with their struct device nodes, which allows sysfs to indicate which tty devices belong to which hardware devices. We also add a serial8250 platform device driver in an initial attempt at PM for ISA ports. However, I'm leaving out the platform device for the time being since adding that would cause potential oops issues.

Convert port autoprobing to set up->capabilities as it discovers various capabilities of the port. Warn when the detected capabilities do not match those in the uart_config table.

It's pointless accessing the LSR value via a pointer all the time - it prevents the compiler optimising it. Also, ensure that we recognise a break sent during a kernel printk correctly.

Add UART_CAP_AFE, and use this to enable TI16C750 flow control, but only if we have 32 bytes or more of FIFO.

This allows us to adapt the FCR for each port type in a much more flexible way, and allows us to set the transmit trigger levels.

The patch below adds power management support to the i2c bus. It adds just two small functions which call down to the devices power management functions if they are present, so the i2c device drivers will receive the suspend and resume events.

This is my port of the lm87 driver to Linux 2.6. It is based on the preliminary work of Jeff Oliver. I then significantly improved the code, added functionality, tested the whole thing on a real motherboard, fixed a couple remaining bugs, and here we are. I'll port a number of improvements and fixes back to the 2.4 version of the driver after lm_sensors 2.8.8 is released (i.e. soon).

A number of messages in the i2c-amd756 and i2c-prosavage drivers have a leading ": " (especially the former). This is a legacy from lm_sensors' printks of the 2.4 times. This patch cleans them up.

This sets the proper name for busses supported by the i2c-amd756 driver. So far, all busses were named AMD756 regardless of the real hardware. Setting the real name is certainly less confusing for the user, and the sensors-detect script expects this too.

Use msleep_interruptible() instead of schedule_timeout() to guarantee the task delays as expected. Remove the unnecessary set_current_state() following the if, as schedule_timeout() [and thus, mlseep_interruptible()] is guaranteed to return in TASK_RUNNING.
