ACPI: Be in TS_POLLING state during mwait based C-state entry ACPI deep C-state entry had a long standing bug/missing feature, wherein we were sending resched IPIs when an idle CPU is in mwait based deep C-state. Only mwait based C1 was using the write to the monitored address to wake up mwait'ing CPU. This patch changes the code to retain TS_POLLING bit if we are entering an mwait based deep C-state. The patch has been verified to reduce the number of resched IPIs in general and also improves the performance/power on workloads with low system utilization (i.e., when mwait based deep C-states are being used).

commit 455c0d71d46e86b0b7ff2c9dcfc19bc162302ee9 Author: Darrick J. Wong <djwong@us.ibm.com> Date: Thu Feb 18 10:28:20 2010 -0800
ACPI: Fix regression where _PPC is not read at boot even when ignore_ppc=0 Earlier, Ingo Molnar posted a patch to make it so that the kernel would avoid reading _PPC on his broken T60. Unfortunately, it seems that with Thomas Renninger's patch last July to eliminate _PPC evaluations when the processor driver loads, the kernel never actually reads _PPC at all! This is problematic if you happen to boot your non-T60 computer in a state where the BIOS _wants_ _PPC to be something other than zero. So, put the _PPC evaluation back into acpi_processor_get_performance_info if ignore_ppc isn't 1. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Len Brown <len.brown@intel.com>

acer-wmi: Respect current backlight level when loading Set the backlight to use the current brightness when loaded, rather than always resetting the backlight to maximum brightness.
