* hwmon/f71805f: Add support for the Fintek F71872F/FG chipJean Delvare2006-12-12
| | | | | | | | | | | | | | | | | Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the same as the Fintek F71805F/FG as far as hardware monitoring is concerned, with two additional internal voltages monitored (VSB and battery), and 6 VID inputs (not yet supported.) To make things a bit more confusing, two of the voltage input pins (in4 and in8) can be used for other functions. The driver reads the pin configuration from the Super-I/O configuration space to decide whether it must create interface files for these inputs or not. Many thanks to Nikolay Derkach for testing the early iterations of this code and reporting bugs. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: New PC87427 hardware monitoring driverJean Delvare2006-12-12
| | | | | | | | | | | This is a new hardware monitoring driver for the National Semiconductor PC87427 Super-I/O chip. It only supports fan speed monitoring for now, while the chip can do much more. Thanks to Amir Habibi at Candelis for setting up a test system, and to Michael Kress for testing several iterations of this driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon/it87: Remove the SMBus interface supportJean Delvare2006-12-12
| | | | | | | | | | | This interface was useless as the LPC ISA-like interface is always available, is faster, and is more reliable. This cuts the driver size by some 20%. This change is also required to later convert the it87 driver to a platform driver, so that we can get rid of i2c-isa in a near future. Signed-off-by: Jean Delvare <khali@linux-fr.org>

| * [PATCH] x86: Fix boot hang due to nmi watchdog init codeRavikiran G Thirumalai2006-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.19 stopped booting (or booted based on build/config) on our x86_64 systems due to a bug introduced in 2.6.19. check_nmi_watchdog schedules an IPI on all cpus to busy wait on a flag, but fails to set the busywait flag if NMI functionality is disabled. This causes the secondary cpus to spin in an endless loop, causing the kernel bootup to hang. Depending upon the build, the busywait flag got overwritten (stack variable) and caused the kernel to bootup on certain builds. Following patch fixes the bug by setting the busywait flag before returning from check_nmi_watchdog. I guess using a stack variable is not good here as the calling function could potentially return while the busy wait loop is still spinning on the flag.

* | | [PATCH] WorkStruct: Use direct assignment rather than cmpxchg()David Howells2006-12-09
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use direct assignment rather than cmpxchg() as the latter is unavailable and unimplementable on some platforms and is actually unnecessary. The use of cmpxchg() was to guard against two possibilities, neither of which can actually occur: (1) The pending flag may have been unset or may be cleared. However, given where it's called, the pending flag is _always_ set. I don't think it can be unset whilst we're in set_wq_data(). Once the work is enqueued to be actually run, the only way off the queue is for it to be actually run. If it's a delayed work item, then the bit can't be cleared by the timer because we haven't started the timer yet. Also, the pending bit can't be cleared by cancelling the delayed work _until_ the work item has had its timer started. (2) The workqueue pointer might change. This can only happen in two cases: (a) The work item has just been queued to actually run, and so we're protected by the appropriate workqueue spinlock. (b) A delayed work item is being queued, and so the timer hasn't been started yet, and so no one else knows about the work item or can access it (the pending bit protects us). Besides, set_wq_data() _sets_ the workqueue pointer unconditionally, so it can be assigned instead. So, replacing the set_wq_data() with a straight assignment would be okay in most cases. The problem is where we end up tangling with test_and_set_bit() emulated using spinlocks, and even then it's not a problem _provided_ test_and_set_bit() doesn't attempt to modify the word if the bit was set. If that's a problem, then a bitops-proofed assignment will be required - equivalent to atomic_set() vs other atomic_xxx() ops.
