From a6e0887f21bbab337ee32d9c0a84d7c0b6e9141b Mon Sep 17 00:00:00 2001 From: Len Brown Date: Sat, 8 Nov 2008 01:21:10 -0500 Subject: [PATCH] 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.
