-Subject: [PATCH] acpi: Update battery information on notification 0x81
-Date: Mon, 16 Aug 2010 16:32:19 -0400
-
-A notification event 0x81 from an ACPI battery device requires us to
-re-read the battery information structure. Do so, and if the battery's
-reporting units have changed (as is the case on some Thinkpads) destroy
-and recreate the battery in order to populate the fields correctly.

-Subject: [PATCH 1/2] mm: page allocator: Adjust the per-cpu counter threshold when memory is low
-
-Commit aa45484 ("calculate a better estimate of NR_FREE_PAGES when memory
-is low") noted that watermarks were based on the vmstat NR_FREE_PAGES. To
-avoid synchronization overhead, these counters are maintained on a per-cpu
-basis and drained both periodically and when a threshold is above a
-threshold. On large CPU systems, the difference between the estimate and
-real value of NR_FREE_PAGES can be very high. The system can get into a
-case where pages are allocated far below the min watermark potentially
-causing livelock issues. The commit solved the problem by taking a better
-reading of NR_FREE_PAGES when memory was low.
-
-Unfortately, as reported by Shaohua Li this accurate reading can consume a
-large amount of CPU time on systems with many sockets due to cache line
-bouncing. This patch takes a different approach. For large machines
-where counter drift might be unsafe and while kswapd is awake, the per-cpu
-thresholds for the target pgdat are reduced to limit the level of drift to
-what should be a safe level. This incurs a performance penalty in heavy
-memory pressure by a factor that depends on the workload and the machine
-but the machine should function correctly without accidentally exhausting
-all memory on a node. There is an additional cost when kswapd wakes and
-sleeps but the event is not expected to be frequent - in Shaohua's test
-case, there was one recorded sleep and wake event at least.
-
-To ensure that kswapd wakes up, a safe version of zone_watermark_ok() is
-introduced that takes a more accurate reading of NR_FREE_PAGES when called
-from wakeup_kswapd, when deciding whether it is really safe to go back to
-sleep in sleeping_prematurely() and when deciding if a zone is really
-balanced or not in balance_pgdat(). We are still using an expensive
-function but limiting how often it is called.
-
-When the test case is reproduced, the time spent in the watermark
-functions is reduced. The following report is on the percentage of time
-spent cumulatively spent in the functions zone_nr_free_pages(),
-zone_watermark_ok(), __zone_watermark_ok(), zone_watermark_ok_safe(),
-zone_page_state_snapshot(), zone_page_state().
-
-vanilla 11.6615%
-disable-threshold 0.2584%

-Subject: [PATCH 2/2] mm: vmstat: Use a single setter function and callback for adjusting percpu thresholds
-
-reduce_pgdat_percpu_threshold() and restore_pgdat_percpu_threshold() exist
-to adjust the per-cpu vmstat thresholds while kswapd is awake to avoid
-errors due to counter drift. The functions duplicate some code so this
-patch replaces them with a single set_pgdat_percpu_threshold() that takes
-a callback function to calculate the desired threshold as a parameter.

-Subject: [PATCH v2] PCI: Disable ASPM if BIOS asks us to
-Date: Mon, 6 Dec 2010 14:00:56 -0500
-Message-Id: <1291662056-6055-1-git-send-email-mjg@redhat.com>
-
-We currently refuse to touch the ASPM registers if the BIOS tells us that
-ASPM isn't supported. This can cause problems if the BIOS has (for any
-reason) enabled ASPM on some devices anyway. Change the code such that we
-explicitly clear ASPM if the FADT indicates that ASPM isn't supported,
-and make sure we tidy up appropriately on device removal in order to deal
-with the hotplug case. If ASPM is disabled because the BIOS doesn't hand
-over control then we won't touch the registers.
-
-Signed-off-by: Matthew Garrett <mjg@redhat.com>
----
-
-Implement Rafael's suggestion to use two separate functions, and also
-ensure that we clear the clkpm bit as well as the ASPM bits.
