2009-06-18ACPI: battery: use .notify method instead of installing handler directlyBjorn Helgaas
This patch adds a .notify() method. The presence of .notify() causes Linux/ACPI to manage event handlers and notify handlers on our behalf, so we don't have to install and remove them ourselves. This driver apparently relies on seeing ALL notify events, not just device-specific ones (because it used ACPI_ALL_NOTIFY). We use the ACPI_DRIVER_ALL_NOTIFY_EVENTS driver flag to request all events.

2009-06-18ACPI: allow drivers to request both device and system notify eventsBjorn Helgaas
System notify events (0x00-0x7f) are common across all device types and should be handled in Linux/ACPI, not in drivers. However, some BIOSes use system notify events in device-specific ways that require the driver to be involved. This patch adds a ACPI_DRIVER_ALL_NOTIFY_EVENTS driver flag. When a driver sets this flag and supplies a .notify method, Linux/ACPI calls the .notify method for ALL notify events on the device, not just the device-specific (0x80-0xff) events.

There is no need to pass a segment/bus tuple to this API, as the callsite always has a struct pci_bus.

2009-06-17ACPI: simplify acpi_pci_irq_add_prt() APIAlexander Chiang
A PCI domain cannot change as you descend down subordinate buses, which makes the 'segment' argument to acpi_pci_irq_add_prt() useless. Change the interface to take a struct pci_bus *, from whence we can derive the bus number and segment. Reducing the number of arguments makes life simpler for callers.

2009-06-17ACPI: eviscerate pci_bind.cAlexander Chiang
Now that we can dynamically convert an ACPI CA handle to a struct pci_dev at runtime, there's no need to statically bind them during boot. acpi_pci_bind/unbind are vastly simplified, and are only used to evaluate _PRT methods on P2P bridges and non-bridge children. This patch also changes the time-space tradeoff ever so slightly. Looking up the ACPI-PCI binding is never in the performance path, and by eliminating this caching, we save 24 bytes for each _ADR device in the ACPI namespace. This patch lays further groundwork to eventually eliminate the acpi_driver_ops.bind callback.

2009-06-17ACPI: Introduce acpi_get_pci_dev()Alexander Chiang
Convert an ACPI CA handle to a struct pci_dev. Performing this lookup dynamically allows us to get rid of the ACPI-PCI binding code, which: - eliminates struct acpi_device vs struct pci_dev lifetime issues - lays more groundwork for eliminating .start from acpi_device_ops and thus simplifying ACPI drivers - whacks out a lot of code This change lays the groundwork for eliminating much of pci_bind.c. Although pci_root.c may not be the most logical place for this change, putting it here saves us from having to export acpi_pci_find_root.

2009-06-17ACPI: make acpi_pci_bind() staticAlexander Chiang

2009-05-29ACPI: sanity check _PSS frequency to prevent cpufreq crashLen Brown
When BIOS SETUP is changed to disable EIST, some BIOS hand the OS an un-initialized _PSS: Name (_PSS, Package (0x06) { Package (0x06) { 0x80000000, // frequency [MHz] 0x80000000, // power [mW] 0x80000000, // latency [us] 0x80000000, // BM latency [us] 0x80000000, // control 0x80000000 // status }, ... These are outrageous values for frequency, power and latency, raising the question where to draw the line between legal and illegal. We tend to survive garbage in the power and latency fields, but we can BUG_ON when garbage is in the frequency field. Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz. So disregard a _PSS with a frequency so large that it can't be represented by cpufreq. https://bugzilla.redhat.com/show_bug.cgi?id=500311 Signed-off-by: Len Brown <len.brown@intel.com>

2009-05-27ACPI: don't check power state after _ON/_OFFBjorn Helgaas
We used to evaluate _STA to check the power state of a device after running _ON or _OFF. But as far as I can tell, there's no benefit to evaluating _STA, and sometimes we trip over bugs when BIOSes don't implement _STA correctly. Yakui says Windows XP doesn't evaluate _STA during power transition. So let's skip it in Linux, too. It's conceivable that we'll need to check _STA in the future for some reason, but until we do, I don't see a reason to clutter this code path.

This patch inverts the logic that distinguishes "Processor" statements from "Device" statements, so we now check explicitly for "Processor" and default to "Device". This removes the only real use of ACPI_PROCESSOR_HID, so we can then remove the #define. It also has the theoretical advantage that if a new processor _HID were ever added, we wouldn't have to change the code here.

2009-05-27PCI/ACPI: fix wrong ref count handling in acpi_pci_bind()Kenji Kaneshige

Because of this, I got the following kernel oops when I was doing some pci hotplug operations.
