ACPI: delete OSI(Linux) DMI dmesg spam 

Linux will continue to ignore OSI(Linux),
except for a white-list containing a few systems.

So delete the black-list,
and stop soliciting user-feedback on the console.

* osi_linux -- Control response to BIOS _OSI(Linux) query. * From pre-history through Linux-2.6.22,

* As Linux evolves, the features that it supports change. * Unfortunately, reference BIOS writers got wind of this

* Unfortunately, Linux-2.6.22 and earlier responded "yes" * For example, OSI(Linux) was used on resume to re-POST a
* to a BIOS _OSI(Linux) query. When * video card on one system, because Linux at that time
* a reference mobile BIOS started using it, its use * could not do a speedy restore in its native driver.
* started to spread to many vendor platforms. * But then upon gaining quick native restore capability,
* As it is not supportable, we need to halt that spread. * Linux has no way to tell the BIOS to skip the time-consuming
* POST -- putting Linux at a permanent performance disadvantage.
* On another system, the BIOS writer used OSI(Linux)
* to infer native OS support for IPMI! On other systems,
* OSI(Linux) simply got in the way of Linux claiming to
* be compatible with other operating systems, exposing
* BIOS issues such as skipped device initialization.
* *
* Today, most BIOS references to _OSI(Linux) are noise -- * So "Linux" turned out to be a really poor chose of
* they have no functional effect and are just dead code * OSI string, and from Linux-2.6.23 onward we respond FALSE.
* carried over from the reference BIOS.
*
* The next most common case is that _OSI(Linux) harms Linux,
* usually by causing the BIOS to follow paths that are
* not tested during Windows validation.
*
* Finally, there is a short list of platforms
* where OSI(Linux) benefits Linux.
*
* In Linux-2.6.23, OSI(Linux) is first disabled by default.
* DMI is used to disable the dmesg warning about OSI(Linux)
* on platforms where it is known to have no effect.
* But a dmesg warning remains for systems where
* we do not know if OSI(Linux) is good or bad for the system.
* DMI is also used to enable OSI(Linux) for the machines
