2007-03-12ACPI: resolve HP nx6125 S3 immediate wakeup regressionAlexey Starikovskiy
Moving disable GPEs from enter_sleep up into sleep_prepare fixed the disabled SCI on S4 on Acer laptops. However, it caused an immediate S3 resume on the HP nx6125. Apparently, on the HP, a GPE was getting re-enabled after the prepare, but before the enter. Close that window by restoring the GPE disable on enter. This is redundant in most cases, but closes this window, where S3 and S4 paths differ.

2007-03-11ACPI: Add support to parse 2nd MADTLen Brown
When a BIOS bug presents multiple APIC/MADTs, Linux currently uses the 1st and ignores the 2nd. But some machines work better if we use the 2nd. http://bugzilla.kernel.org/show_bug.cgi?id=7465 Add a warning and boot parameter "acpi_apic_instance=2" to allow parsing the 2nd. No change to default behaviour in this patch. Signed-off-by: Len Brown <len.brown@intel.com>

2007-03-09ACPI: ec: fix race in status register accessAlexey Starikovskiy
Delay the read of the EC status register until after the event that caused it occurs -- otherwise it is possible to read and act on stale status that was associated with the previous event. Do this with a perpetually incrementing "event_count" to detect when a new event occurs and it is safe to read status. There is no workaround for polling mode -- it is inherently exposed to reading and acting on stale status, since it doesn't have an interrupt to tell it the event completed. http://bugzilla.kernel.org/show_bug.cgi?id=8110 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

It is useful to know whether your laptop is docked or not, but it is even more useful to know which docking station it's docked to. Attached patch adds "uid" file to sysfs.

2007-03-09ACPI: make blacklist more verboseAnthony Godshall, Ampro Computers, Inc
IMHO, ACPI disabled due to DMI failure or blacklisted year should be noted, as is done with other ACPI blacklisting. This will help people troubleshoot when ACPI isn't working. Status quo is a mysterious "ACPI Disabled" message without explanation on BIOS that implements ACPI but not DMI. This is actually fairly common on embedded x86 boards.

2007-02-16[PATCH] clockevents: i386 driversThomas Gleixner
Add clockevent drivers for i386: lapic (local) and PIT/HPET (global). Update the timer IRQ to call into the PIT/HPET driver's event handler and the lapic-timer IRQ to call into the lapic clockevent driver. The assignement of timer functionality is delegated to the core framework code and replaces the compile and runtime evalution in do_timer_interrupt_hook() Use the clockevents broadcast support and implement the lapic_broadcast function for ACPI. No changes to existing functionality.
