ACPI: ec: fix race in status register access
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.

ACPI: make blacklist more verbose
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.

asus-laptop: make code static
This patch makes some needlessly global code static.

libata-acpi: allow _GTF on SATA, but disable on PATA for now
The ACPI specification states, and BIOS implementations depend on, _STM being called before _GTF.
SATA does this, but PATA does not. So for now, simply prevent execution of _GTF on PATA devices. Longer term we should implement ACPI support for PATA devices in libata.

ACPI: repair nvidia early quirk breakage on x86_64
x86_64 nvidia_bugs() broke when we bailed out on not finding the HPET. However, the quirk works by checking for not finding the HPET...
Delete the nvidia_hpet_detected flag and simply test for not finding the HPET, which is simple to do now that acpi_table_parse returns 1 on failure.

ACPI: fix parallel port IRQ after resume from S3
The PNPACPI resource flags were broken.
This would apply to re-enabling a device any-time after boot, not just after resume from S3.

ACPI: ibm-acpi: improve backlight power handling
Improve the backlight code to emulate as much as possible the power management events, as we are unable to really power on or power off the backlight.

ACPI: fix boot hang w/o "noapic" on MSI MS-6390-L
This is a workaround to handle a BIOS bug where the programmer exchanged the name and index fields of a _PRT entry. Apparently this BIOS error does not confuse Windows and thus it lurks in the field on various machines.
boot with "acpi=strict" to disable this workaround

ACPI: fix Thinkpad 600/600E/600X interrupts

sony-laptop: fix uninitialised variable

ACPICA: Fix ACPI Global Lock re-entrancy
patch "Delete recursive feature of ACPI Global Lock" broke re-entrancy of the Global Lock.
The common routine to acquire GL is acpi_ev_acquire_global_lock, so check for re-entrancy _must_ be there, and not anywhere else.

ACPI: Altix: reinitialize acpi tables
To provide compatibilty with SN kernels that do and do not have ACPI IO support, the SN PROM must build different versions of some ACPI tables based on which kernel is booting. As such, the tables may have to change at kernel boot time. By default, prior to kernel boot, the PROM builds an empty DSDT (header only) and no SSDTs. If an ACPI capable kernel boots, the kernel will notify the PROM, at platform setup time, and the PROM will build full DSDT and SSDT tables.
With the latest changes to acpi_table_init(), the table lengths are saved, and when our PROM changes them, the changes are not seen, and the kernel will crash on boot. Because of issues with kexec support, we are not able to create the tables prior to acpi_table_init(). As a result, we are making a second call to acpi_table_init() to process the rebuilt DSDT and SSDTs.

ACPI: Altix: cannot register acpi bus driver before bus scan
SN code to initialize the Hub/TIO infrastructure needs to execute before bus scanning. This was previously done with an early call to acpi_bus_register_driver(). But now that ACPI is using the Linux driver model, a driver cannot be registered that early. Make changes to have the init routines invoked via calls to acpi_get_devices().
