Subject: Re: [PATCH 1/3] ACPICA: expose OSI version

From: Aaron Lu <aaron.lu@...el.com>

Expose acpi_gbl_osi_data so that code outside of ACPICA can check
the value of the last successfull _OSI call.  The definitions for
OSI versions are moved to actypes.h so that other components can
access them too.

Based on a patch from Matthew Garrett which in turn was based on
an earlier patch from Seth Forshee.
