The patch titled
cpufreq: powernow-k8 cleanup msg if BIOS does not export ACPI _PSS cpufreq data
has been removed from the -mm tree. Its filename was
cpufreq-powernow-k8-cleanup-msg-if-bios-does-not-export-acpi-_pss-cpufreq-data.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: cpufreq: powernow-k8 cleanup msg if BIOS does not export ACPI _PSS cpufreq data
From: Thomas Renninger <trenn@xxxxxxx>
- Make the message shorter and easier to grep for
- Use printk_once instead of WARN_ONCE (functionality of these was mixed up)
Also see bug: http://bugzilla.kernel.org/show_bug.cgi?id=13146 for
reference.
(akpm: the kernel warning is misleading - change it to blame sthe BIOS
vendor and not us ;)
