2009-09-21trivial: doc: hpfall: accept disk device to unload as argumentFrans Pop
Allows users who use an IDE driver for their disk to use hpfall without having to modify the source. By default /dev/sda is used. Suggested by Christian Thaeter in http://lkml.org/lkml/2009/3/25/505. While we're add it, improve error message if opening /dev/freefall fails.

2009-09-21trivial: doc: hpfall: reduce risk that hpfall can do harmChristian Thaeter
Improve the example code to be at least useable, as in not causing harm (as shown below). Code can still be improved further, but this adds some basic safeguards. 1. hpfall *MUST* mlockall(MCL_CURRENT|MCL_FUTURE); itself! Since the Program sits and waits most of the time it becomes very likely swapped out. If it gets woken up when the laptop drops from the table while it is swapped out it actually triggers harddrive activity! 2. Daemonize hpfall using 'daemon(0,0)' (quick and dirty). 3. Give hpfall realtime priority. Should give a chance that it has less latency when woken up.

Monitoring is provided for the system voltages supported natively by the WM831x, the chip temperature, the battery temperature and the auxiliary inputs of the WM831x. Currently no alarms are supported, though digital comparators on the WM831x devices would allow these to be provided. Since the auxiliary and battery temperature input scaling depends on the system configuration the value is reported as a voltage to userspace.

2009-09-15sparc: Kill PROM console driver.David S. Miller
Many years ago when this driver was written, it had a use, but these days it's nothing but trouble and distributions should not enable it in any situation. Pretty much every console device a sparc machine could see has a bonafide real driver, making the PROM console hack unnecessary. If any new device shows up, we should write a driver instead of depending upon this crutch to save us. We've been able to take care of this even when no chip documentation exists (sunxvr500, sunxvr2500) so there are no excuses. Signed-off-by: David S. Miller <davem@davemloft.net>

2009-09-15uio: add generic driver for PCI 2.3 devicesMichael S. Tsirkin
This adds a generic uio driver that can bind to any PCI device. First user will be virtualization where a qemu userspace process needs to give guest OS access to the device. Interrupts are handled using the Interrupt Disable bit in the PCI command register and Interrupt Status bit in the PCI status register. All devices compliant to PCI 2.3 (circa 2002) and all compliant PCI Express devices should support these bits. Driver detects this support, and won't bind to devices which do not support the Interrupt Disable Bit in the command register. It's expected that more features of interest to virtualization will be added to this driver in the future. Possibilities are: mmap for device resources, MSI/MSI-X, eventfd (to interface with kvm), iommu. Signed-off-by: Michael S.

2009-09-14ftrace: document function and function graph implementationMike Frysinger

So after pounding out support for the Blackfin arch, start documenting the requirements/details.
