Hi Linus, please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release This request is larger than I'd prefer at -rc3, but as I wasn't available for an -rc2 merge, some things waited until now. The good news is that the larger text changes are low risk. The EC changes are tweaks to the -rc0 update -- as we've learned about new and creative ways that vendors can make their EC's violate spec... Thanks to Alexey for being extremely responsive in debugging these... Fixed a popular battery oops regression. Fixed a boot hang on some unusual AMD boxes seen with the new CPU_IDLE. Fixed a long-standing IRQ8 issue that some OEMs and Linux distros are eagerly awaiting. Fixed the processor throttling extensions that we first started supporting in 2.6.23. The reality is that it took until now to properly test the code, as only very new platforms have it. And a couple of small cleanups -- the larger ones are waiting for 2.6.25. thanks! -Len 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/2.6.24/acpi-release-20070126-2.6.24-rc3.diff.gz Documentation/thinkpad-acpi.txt | 73 +++--- arch/x86/kernel/acpi/processor.c | 3 arch/x86/kernel/acpi/sleep_64.c | 3 arch/x86/kernel/io_apic_32.c | 21 + arch/x86/kernel/io_apic_64.c | 24 +- arch/x86/pci/acpi.c | 2 drivers/acpi/Kconfig | 18 + drivers/acpi/Makefile | 2 drivers/acpi/ac.c | 20 - drivers/acpi/battery.c | 22 + drivers/acpi/ec.c | 43 ++- drivers/acpi/osl.c | 25 -- drivers/acpi/processor_core.c | 14 - drivers/acpi/processor_idle.c | 111 +++++---- drivers/acpi/processor_throttling.c | 286 ++++++++++++++++++------ drivers/acpi/sbs.c | 43 ++- drivers/acpi/tables/tbutils.c | 2 drivers/acpi/video.c | 155 ++++++------- drivers/misc/thinkpad_acpi.c | 231 ++++++++++++++----- drivers/misc/thinkpad_acpi.h | 4 drivers/pnp/pnpacpi/rsparser.c | 24 +- include/acpi/processor.h | 1 include/linux/acpi.h | 5 include/linux/cpuidle.h | 1 24 files changed, 769 insertions(+), 364 deletions(-) through these commits: Adrian Bunk (2): x86_64: remove acpi_pci_link_exit() x86: acpi_pciprobe_dmi_table[] must be __devinitdata Alexey Starikovskiy (3): ACPI: EC: Workaround for optimized controllers ACPI: Split out control for /proc/acpi entries from battery, ac, and sbs.

This will cause an oops in power_supply_show_property() when it reads off the end of the status_text array. This actually was causing a 100% reproducible crash on boot on my laptop with two batteries, when one battery was completely drained and the laptop was not plugged in. Fix this by making sure acpi_battery_get_property() returns POWER_SUPPLY_STATUS_UNKNOWN for any battery state it doesn't already handle explicitly. There doesn't seem to be any status enum value defined that makes more sense than 'unknown' for a battery at a critical charge level.

Fix it.

This still allows signals to be delivered ASAP, which is much nicer than just doing mutex_lock, and still shadows userspace from EINTR when SA_RESTART is active. Problem reported by Peter Jordan.

It should be used instead of the native thinkpad backlight brightness control interface when possible. This patch disables the native brightness support in the driver by default when we detect that the standard ACPI interface is available. The local admin can still enable it using the module parameter "brightness_enable". Note that we need to detect the standard ACPI backlight interface only in boxes for which we would load the native backlight interface in the first place, and that no ThinkPad BIOS has _BCL but misses the other methods, so the detection routines can be really simple.

It can also be used to force the backlight support to be enabled, but that is currently a no-op as the backlight support is enabled by default when available. This will be changed by a different patch.

They also have standard ACPI backlight brightness control. We detect the number of brightness levels by the presence of a BCLL package with 16 entries. If BCLL is not there, we assume eight levels (Z6*). If it is there, but it doesn't have 16 entries, we assume eight levels (T60). Otherwise we assume sixteen levels (T61, X61, etc). We don't use _BCL because it can have side-effects in thinkpads. Thanks to Thomas Renninger <trenn@xxxxxxx> for notifying me of this potential problem. Using the standard ACPI backlight brightness control *instead* of the native thinkpad backlight control is a better idea, though. A different patch will take care of this.

That commit made some modifications to the default keymaps that cause bad behaviour on all IBM ThinkPads if HAL doesn't know to change them into passive (on-screen-display only) events. The proper solution for IBM ThinkPads is to use the _NOTIFY version of the key codes for the IBM default map (which are not available in mainline yet), and for the Lenovo keymap, it will take some studying of the various DSDTs and testing to know the best path (which I will do shortly).
