WMI

ANYWR - Another New Year WMI release

Len,

Can you please review at least the first two patches in this series, as I would still really like to try and get them into 2.6.25.

-Carlos

===

Patch #1: (WMI - driver and in kernel interface) - Fix ACPI debug issues

Fix the compile errors with ACPI debugging enabled.

Len: For you to review, and to go upstream.

====

Patch #2: (acer-wmi) - No change

Len: For you to review, and to go upstream.

====

Patch #3: (tc1100-wmi) - No Change

RFC only, needs actual testing on the hardware, and probably very broken. Waiting on Matthew Garrett to get some free time to test this.

====

Patch #4: (WMI sysfs interface) - Added new in-kernel function

RFC only (see patch #5 for reason and discussion). Adds interface under /sys/devices/virtual/wmi

Also adds a function to return the (virtual) device associated with a GUID for use by other parts of the kernel that want to set a parent device.

====

Patch #5: (WMI sysfs workaround) - No change

Temporary hack, needed to get patch #4 working, due to a limitation on bus_id length (Kay Sievers is apparently working on this, ref Greg KH[1]).

Apparently, the necessary fixes _might_ go into 2.6.25 as well, or worst case scenario is 2.6.26[2]. So we can either:

1) Hold off on patch #4 until the necessary fixes go in (this might be 2.6.25 if we're lucky, or we end up putting off WMI sysfs support until 2.6.26)

or

2) Apply patch #4, and #5 on top as a temporary hack, and then revert #5 as soon as the necessary changes go in. (For bisection purposes, #4 and #5 should be merged if we go ahead with this).

I don't know what would be the best solution here.
