Hi Linus, please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release Two regression fixes (battery driver oops on load, ACPI warnings on sony laptops), a couple of merge-window stragglers, and some cleanups. This will update the files shown below. thanks! -- Len Brown Intel Open Source Technology Center ps. individual patches are available on linux-acpi@xxxxxxxxxxxxxxx and a consolidated plain patch is available here: ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.30/acpi-release-20090320-2.6.30-rc1.diff.gz arch/x86/include/asm/cpufeature.h | 1 + arch/x86/kernel/apic/apic.c | 6 +++ arch/x86/kernel/cpu/addon_cpuid_features.c | 1 + arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.c | 55 ++++++++++++----------- arch/x86/kernel/cpu/cpufreq/longhaul.c | 1 - drivers/acpi/acpica/hwvalid.c | 1 - drivers/acpi/battery.c | 2 +- drivers/acpi/proc.c | 13 ++---- drivers/acpi/processor_idle.c | 3 + drivers/acpi/scan.c | 31 +++++-------- drivers/acpi/sleep.h | 3 + drivers/acpi/thermal.c | 68 +++++++++++++++------------ drivers/acpi/video.c | 30 ++---------- drivers/acpi/wakeup.c | 30 +++--------- drivers/platform/x86/fujitsu-laptop.c | 60 ++++--------------------- drivers/platform/x86/panasonic-laptop.c | 28 +++--------- drivers/platform/x86/sony-laptop.c | 30 ++----------- drivers/platform/x86/wmi.c | 15 +----- include/acpi/acpi_bus.h | 1 - 19 files changed, 131 insertions(+), 248 deletions(-) through these commits: Bjorn Helgaas (7): ACPI: thermal: use .notify method instead of installing handler directly ACPI: video: use .notify method instead of installing handler directly fujitsu-laptop: use .notify method instead of installing handler directly fujitsu-laptop: use .notify method instead of installing hotkey handler directly panasonic-laptop: use .notify method instead of installing handler directly sony-laptop: use .notify method instead of installing handler directly ACPI: WMI: use .notify method instead of installing handler directly Hannes Eder (1): NULL noise: drivers/platform/x86/panasonic-laptop.c Huang Weiyi (1): ACPI: cpufreq: remove dupilcated #include Jean Delvare (1): ACPI: Adjust Kelvin offset to match local implementation Len Brown (2): ACPI: delete acpi_device.g_list ACPICA: delete check for AML access to port 0x81-83 Shaohua Li (1): ACPI: convert acpi_device_lock spinlock to mutex Vegard Nossum (1): ACPI battery: fix async boot oops Venkatesh Pallipadi (3): ACPI x86: Cleanup acpi_cpufreq structures related to aperf/mperf ACPI x86: Make aperf/mperf MSR access in acpi_cpufreq read_only x86 ACPI: Add support for Always Running APIC timer with this log: commit 8897c1859521cf33077256725b2377164b130c75 Merge: 18b2646 db954b5 fdbdc7f 13614e3 33b5715 f61bb93 Author: Len Brown <len.brown@xxxxxxxxx> Date: Tue Apr 7 18:18:42 2009 -0400 Merge branches 'release', 'APERF', 'ARAT', 'misc', 'kelvin', 'device-lock' and 'bjorn.notify' into release commit db954b5898dd3ef3ef93f4144158ea8f97deb058 Author: Venkatesh Pallipadi <venkatesh.pallipadi@xxxxxxxxx> Date: Mon Apr 6 18:51:29 2009 -0700 x86 ACPI: Add support for Always Running APIC timer Add support for Always Running APIC timer, CPUID_0x6_EAX_Bit2. This bit means the APIC timer continues to run even when CPU is in deep C-states. The advantage is that we can use LAPIC timer on these CPUs always, and there is no need for "slow to read and program" external timers (HPET/PIT) and the timer broadcast logic and related code in C-state entry and exit.

This theory is supported by the fact that the bad RIP value is a vmalloc address. The immediate fix is to make this a non-init call. (A better long-term fix is of course to wait with init-section unloading until a module's async initcalls have been run, which would allow us to discard this function which is still only run once, after all. Perhaps a new async_initcall() function for the async/module API, if this is needed for other modules in the future?)

However ACPI handles temperature values with a single decimal place. As a consequence, some implementations use an offset of 273.1 and others use an offset of 273.2. Try to find out which one is being used, to present the most accurate and visually appealing number. Tested on a Sony Vaio PGC-GR214EP (which uses 273.1) and a Lenovo Thinkpad T60p (which uses 273.2).
