* hwmon: (k10temp) Blacklist more family 10h processorsClemens Ladisch2010-01-10
| | | | | | | | | | | The latest version of the Revision Guide for AMD Family 10h Processors lists two more processor revisions which may be affected by erratum 319. Change the blacklisting code to correctly detect those processors, by implementing AMD's recommended algorithm.

* hwmon: (asus_atk0110) Add debugfs interfaceLuca Tettamanti2010-01-10
| | | | | | | | | | | Expose the raw GGRP/GITM interface via debugfs. The hwmon interface is reverse engineered and the driver tends to break on newer boards... Using this interface it's possible to poke directly at the ACPI methods without the need to recompile, reducing the guesswork and the round trips needed to support a new revision of the interface.

* hwmon: (asus_atk0110) Refactor interface probe codeLuca Tettamanti2010-01-10

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Blackfin needs it own arch specific probe_kernel_read() and probe_kernel_write(). This was moved out of the kgdb code and into the arch/blackfin/maccess.c, because it is a generic kernel api. The arch specific kgdb.c for blackfin was cleaned of all functions which exist in the kgdb core that do the same thing after resolving the probe_kernel_read() and probe_kernel_write(). This also eliminated the need for most of the #include's.

Hence, the reiserfs lock may be acquired twice which is not wanted as reiserfs_setattr() calls journal_begin() that is going to try to relax the lock in order to safely acquire the journal mutex. Using reiserfs_write_lock_once() from reiserfs_setattr() solves the problem. This fixes the following warning, that precedes a lockdep report.

Anything using clk_mpll directly really should not be relying on this being the clock that is eventually routed to a peripheral, so remove the loop and ensure that the clocks accurately represent the clock chain in the device. The clk_mpll is not being used outside of the s3c6400-clock.c code, so this change should not break anything else. Do the same for the EPLL. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

With this change, we can run into a situation where an irq cleanup interrupt on a cpu can cleanup the vector mappings associated with multiple irqs, of which one of the irq's migration might be still in progress. As such when that irq hits the old cpu, we get the "No IRQ handler" messages. Fix this by checking for the irq_cfg's move_in_progress and if the move is still in progress delay the vector cleanup to another irq cleanup interrupt request (which will happen when the irq starts arriving at the new cpu destination).

Although this is against the PCI specification, we can handle it quite easily by allowing drivers to define arbitrary D3 delays for devices known to require extra time for switching power states. Introduce additional field d3_delay in struct pci_dev and use it to store the value of the device's D0->D3 delay, in miliseconds. Make the PCI PM core code use the per-device d3_delay unless pci_pm_d3_delay is greater (in which case the latter is used). [This also allows the driver to specify d3_delay shorter than the 10 ms required by the PCI standard if the device is known to be able to handle that.] Make the sky2 driver set d3_delay to 150 for devices handled by it.
