Add support for the automatic fan speed control interface as implemented by IT8705F chips up to revision F and IT8712F chips up to revision G. This implementation fits very well in our standard sysfs interface. I implemented the old and not the new interface because the only chip I have at hand is an old one, and the new interface is more difficult to map to the standard sysfs interface. Adding support later should be possible though, if someone with a supported chip is interested. Signed-off-by: Jean Delvare <khali@linux-fr.org>

The IT87xxF chips support beeping on alarm, if properly wired and configured. There is one control bit for each input type (temperature, fan, voltage.) Let the user see and change them. Signed-off-by: Jean Delvare <khali@linux-fr.org>

Only VID-related attributes are left in it87_attributes_opt, so we might as well rename it to it87_attributes_vid and use this group to create all attributes at once. Signed-off-by: Jean Delvare <khali@linux-fr.org>

Jean Delvare authored
There is a lot of code redundancy in the creation of the fan and pwm attributes. Move these attributes to arrays so that the code can be simplified. This in turns makes the attributes removal code larger, so move it to a separate function that can be called in both the standard removal case and the error path during probing.

Let the user read the PWM-to-temperature mappings. Until the trip points are also exposed, this is essentially a way to know how the BIOS has set things up. The ability to change the settings will be added later, together with the trip points. Signed-off-by: Jean Delvare <khali@linux-fr.org>

The it87 driver doesn't yet support automatic fan control. Let it at least tell the user when a fan output is in automatic mode. Also let the user switch from automatic mode (possibly set by the BIOS) to manual mode and back without losing the settings. Signed-off-by: Jean Delvare <khali@linux-fr.org>

Tested successfully with an ADM1032 chip on its evaluation board. It should work fine with all other chips as well. At this point this is more of a proof-of-concept, we don't do anything terribly useful on SMBus alert: we simply log the event. But this could later evolve into libsensors signaling so that user-space applications can take an appropriate action.

If the calling convention of ->timer_fn() and ->cleanup_fn() are unified across hardware versions we can drop parameters to ioat_init_channel() and unify ioat_is_dma_complete() implementations. Both ->timer_fn() and ->cleanup_fn() are modified to expect a struct dma_chan pointer. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

The hardware automatically disables further interrupts after each event until rearmed. This allows a delay to be injected between the occurence of the interrupt and the running of the cleanup routine. The delay is scaled by the descriptor backlog and then written to the INTRDELAY register which specifies the number of microseconds to hold off interrupt delivery after an interrupt event occurs. According to powertop this reduces the interrupt rate from ~5000 intr/s to ~150 intr/s per without affecting throughput (simple dd to a raid6 array).

Since ioat_cleanup_preamble() and the update of the last completed descriptor are not synchronized there is a chance that two cleanup threads can see descriptors to clean. If the first cleans up all pending descriptors then the second will trigger the BUG_ON. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

This makes sure that we pick the synchronous signals caused by a processor fault over any pending regular asynchronous signals sent to use by [t]kill(). This is not strictly required semantics, but it makes it _much_ easier for programs like Wine that expect to find the fault information in the signal stack. Without this, if a non-synchronous signal gets picked first, the delayed asynchronous signal will have its signal context pointing to the new signal invocation, rather than the instruction that caused the SIGSEGV or SIGBUS in the first place. This is not all that pretty, and we're discussing making the synchronous signals more explicit rather than have these kinds of implicit preferences of SIGSEGV and friends. See for example http://bugzilla.kernel.org/show_bug.cgi?id=15395 for some of the discussion. But in the meantime this is a simple and fairly straightforward work-around, and the whole if (x & Y) x &= Y; thing can be compiled into (and gcc does do it) just three instructions: movq %rdx, %rax andl $Y, %eax cmovne %rax, %rdx so it is at least a simple solution to a subtle issue.

To avoid potential problems with an empty /dev open /dev/console from rootfs instead of waiting to mount our root filesystem and mounting it there. This effectively guarantees that there will be a device node, and it won't be on a filesystem that we will ever unmount, so there are no issues with leaving /dev/console open and pinning the filesystem. This is actually more effective than automatically mounting devtmpfs on /dev because it removes removes the occasionally problematic assumption that /dev/console exists from the boot code. With this patch I was able to throw busybox on my /boot partition (which has no /dev directory) and boot into userspace without problems. The only possible negative consequence I can think of is that someone out there deliberately used did not use a character device that is major 5 minor 2 for /dev/console. Does anyone know of a situation in which that could make sense? Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Add a new UMOUNT_NOFOLLOW flag to umount(2). This is needed to prevent symlink attacks in unprivileged unmounts (fuse, samba, ncpfs). Additionally, return -EINVAL if an unknown flag is used (and specify an explicitly unused flag: UMOUNT_UNUSED). This makes it possible for the caller to determine if a flag is supported or not.
